**What's new**
* Bring support for the Bananapi BPi-R64 to the level desirable for
a nice hackable routerboard.
* Use ARM Trusted Firmware A from source. (goodbye binary preloader)
* Use Das U-Boot from source. (see previous commit)
* Assemble SD-card image using OpenWrt image-commands.
(no gen_sd_cruz_foo.sh added, this is not Raspbian)
* Updated kernel options to support root filesystem.
* Updated DTS to match OpenWrt LAN ports, known LEDs, buttons, ...
* Detect root device, handle sysupgrade, config restore, ...
* Wire up (known) LEDs and buttons in OpenWrt-fashion.
* Build one set of images from SD-card and eMMC.
* Hopefully provide a good example of how things can be done right
from scratch.
**Installation and images**
* Have an empty SD-card at hand
* Write stuff to the card, as root (card device is /dev/mmcblkX)
- write header, gpt, bl2, atf, u-boot and recovery kernel:
`cat *bpi-r64-boot-sdcard.img *bpi-r64-initramfs-recovery.fit > /dev/mmcblkX`
- rescan partitions:
`blockdev --rereadpt /dev/mmcblkX`
- write main system to production partition:
`cat *bpi-r64-squashfs-sysupgrade.fit > /dev/mmcblkXp5`
* Installation to eMMC works using SD-card bootloader via TFTP
When running OpenWrt of SD-card, issue this to trigger installation
to eMMC:
`fw_setenv bootcmd run emmc_init`
Be prepared to serve the content of bin/targets/mediatek/mt7622 on
TFTP server address 192.168.1.254.
**What's missing**
* The red LED is always on, probably a hardware bug.
* AHCI (probably needs DTS changes)
* Ship SD-card image ready with every needed for eMMC install.
* The eMMC has a second, currently unused boot partition. This would
be ideal to store the WiFi EEPROM and Ethernet MAC address(es).

The vendor flash layout of the Linksys E8450 is problematic as it uses
the SPI-NAND chip without any wear-leveling while at the same time
wasting a lot of space for padding.
Use an all-UBI layout instead, storing the kernel+dtb+squashfs in
uImage.FIT standard format in UBI volume 'fit', the read-write
overlay in UBI volume 'rootfs_data' as well as reduntant U-Boot
environments 'ubootenv' and 'ubootenv2', and a 'recovery'
kernel+dtb+initramfs uImage.FIT for dual-boot.
** WARNING **
THIS PROCEDURE CAN EASILY BRICK YOUR DEVICE PERMANENTLY IF NOT CARRIED
OUT VERY CAREFULLY AND EXACTLY AS DESCRIBED!
Step 0
* Configure your PC to have the static IPv4 address 192.168.1.254/24
* Provide bin/targets/mediatek/mt7622 via TFTP
Now continue EITHER with step 1A or 1B, depending on your preference
(and on having serial console wired up or not).
Step 1A (Using the vendor web interface (or non-UBI OpenWrt install))
In order to update to the new bootloader and UBI-based firmware,
use the web browser of your choice to open the routers web-interface
accessible on http://192.168.1.1
* Navigate to
'Configuration' -> 'Administration' -> 'Firmware Upgrade'
* Upload the file
openwrt-mediatek-mt7622-linksys_e8450-ubi-initramfs-recovery.itb
and proceed with the upgrade.
* Once OpenWrt comes up, use SCP to upload the new bootloader files to
/tmp on the router:
*-mt7622-linksys_e8450-ubi-preloader.bin
*-mt7622-linksys_e8450-ubi-bl31-uboot.fip
* Connect via SSH as you will now need to replace the bootloader in
the Flash.
ssh root@192.168.1.1
(the usual warnings)
* First of all, backup all the flash now:
for mtd in /dev/mtdblock*; do
dd if=$mtd of=/tmp/$(basename $mtd);
done
* Then use SCP to copy /tmp/mtdblock* from the router and keep them
safe. You will need them should you ever want to return to the
factory firmware!
* Now flow the uploaded files:
mtd -e /dev/mtd0 write /tmp/*linksys_e8450-ubi-preloader.bin /dev/mtd0
mtd -e /dev/mtd1 write /tmp/*linksys_e8450-ubi-bl31-uboot.fip /dev/mtd1
If and only if both writes look like the completed successfully
reboot the router. Now continue with step 2.
Step 1B (Using the vendor bootloader serial console)
* Use the serial to backup all /dev/mtd* devices before using the
stock firmware (you got root shell when connected to serial).
* Then reboot and select 'U-Boot Console' in the boot menu.
* Copy the following lines, one by one:
tftpboot 0x40080000 openwrt-mediatek-mt7622-linksys_e8450-ubi-preloader.bin
tftpboot 0x40100000 openwrt-mediatek-mt7622-linksys_e8450-ubi-bl31-uboot.fip
nand erase 0x0 0x180000
nand write 0x40080000 0x0 0x180000
reset
Now continue with step 2
Step 2
Once the new bootchain comes up, the loader will initialize UBI and the
ubootenv volumes. It will then of course fail to find any bootable
volume and hence resort to load kernel via TFTP from server
192.168.1.254 while giving itself the address 192.168.1.1
The requested file is called
openwrt-mediatek-mt7622-linksys_e8450-ubi-initramfs-recovery.itb
and your TFTP server should provide exactly that :)
It will be written to UBI as recovery image and booted.
You can then continue and flash the production OS image, either
by using sysupgrade in the booted initramfs recovery OS, or by using
the bootloader menu and TFTP.
That's it. Go ahead and mess around with a bootchain built almost
completely from source (only DRAM calibration blobs are fitted in bl2,
and the irreplacable on-chip ROM loader remains, of course).
And enjoy U-Boot built with many great features out-of-the-box.
You can access the bootloader environment from within OpenWrt using the
'fw_printenv' and 'fw_setenv' commands. Don't be afraid, once you got
the new bootchain installed the device should be fairly unbrickable
(holding reset button before and during power-on resets things and
allows reflashing recovery image via TFTP)
Special thanks to @dvn0 (Devan Carpenter) for providing amazingly fast
infra for test-builds, allowing for `make clean ; make -j$(nproc)` in
less than two minutes :)

MediaTek targets always use U-Boot's modern uImage.FIT format which
allows bundling several blobs into a single file including hashes,
descriptions and more. In fact, we are already using that to bundle
the Flattened Device Tree blob with the kernel on this and many
other targets.
In the same fashion, we can now make use of the newly introduced
support for building seperate ramdisk to uImage.FIT with a dedicated
initrd blob checked and loaded by U-Boot instead of embedding the
cpio archive into the kernel itself.
This allows for having larger ramdisks, choosing ramdisk compression
independently of kernel compression (while only kernel is decompressed
by the bootloader) and for more easily replacing or modifying the
filesystem contained in an initramfs image.

Opening the case
----------------
Opening the case is not a nice task, as itis glued together. Insert a
flat knife between the front and back casing below the ethernet port.
Open up a gap this way and insert a flat scredriver, remove the knife.
Work your way around the casing by applying force to seperate the front
and back casing. This losens the glue and opens the plastic clips. Be
gentle, as these clips are very cheap and break quickly.
Installation
------------
1. Connect to the booted device at 192.168.1.20 using username/password
"ubnt".
2. Transfer the OpenWrt sysupgrade image to the device using SCP.
3. Check the mtd partition number for bs / kernel0 / kernel1
$ cat /proc/mtd
4. Set the bootselect flag to boot from kernel0
$ dd if=/dev/zero bs=1 count=1 of=/dev/mtdblock6
5. Write the OpenWrt sysupgrade image to both kernel0 as well as kernel1
$ dd if=openwrt.bin of=/dev/mtdblock8
$ dd if=openwrt.bin of=/dev/mtdblock9
6. Reboot the device. It should boot into OpenWrt.

The majority of our targets provide a default value for the variable
SUPPORTED_DEVICES, which is used in images to check against the
compatible on a running device:
SUPPORTED_DEVICES := $(subst _,$(comma),$(1))
At the moment, this is implemented in the Device/Default block of
the individual targets or even subtargets. However, since we
standardized device names and compatible in the recent past, almost
all targets are following the same scheme now:
device/image name: vendor_model
compatible: vendor,model
The equal redundant definitions are a symptom of this process.
Consequently, this patch moves the definition to image.mk making it
a global default. For the few targets not using the scheme above,
SUPPORTED_DEVICES will be defined to a different value in
Device/Default anyway, overwriting the default. In other words:
This change is supposed to be cosmetic.
This can be used as a global measure to get the current compatible
with: $(firstword $(SUPPORTED_DEVICES))

It turns out that 'echo -e' isn't portable; it doesn't work in the dash
builtin echo and Ubuntu users are complaining.
I can't even get octal (specified by POSIX) to work consistently because
those variants of 'echo' which *do* support -e don't seem to interpret
octalwithout it.
I could switch to /bin/echo but using -e with that isn't actually
portable *either* even though it works today.
For now just stick with bash, and use its builtin. We may end up using

Many MediaTek SoCs can be unbricked by using the SP Flash Tool from
http://spflashtool.com/ along with a "scatter list" file, which is
just a text file listing which image gets loaded where.
We use a trivial partition layout for the tool, with the whole eMMC
image as a single "partition", which means users just need to unzip
the sysupgrade image. Doing the real partition layout would be overly
complex and would require the individual partitions to be shipped
as artifacts — or users to extract them out of the sysupgrade image
just for the tool to put them adjacent to each other on the eMMC
anyway.
The tool does require a copy of the preloader in order to operate,
even when it isn't flashing the preloader to the eMMC boot region.
So drop that into the bin directory as an artifact too.

This board ships with an ancient 14.07-based OpenWrt using block2mtd, and
the MBR partition table contains nonsense.
It is possible to sysupgrade to an upstream OpenWrt image, but the
legacy layout of the OpenWrt images start at 0xA00 in the eMMC, with
a raw uImage. The legacy OpenWrt image doesn't "own" the beginning
of the device, including the MBR and U-Boot.
This means that when a user upgrades to upstream OpenWrt, it doesn't
boot because it can't find the right partitions. So hard-code them on
the kernel's command line using CONFIG_CMDLINE_PARTITION (for block).
Additionally, the vendor firmware doesn't cope with images larger than
about 36MiB, because it only overwrites the contents of its "firmware"
MTD partition. The current layout of the legacy image wastes a lot of
space, allowing over 32MiB for the kernel and another 10MiB for the FAT
recovery file system which is only created as 3MiB. So pull those in
to allow 4¾ MiB for the kernel, 3MiB for recovery, and then we have over
20MiB for the root file system.
This doesn't affect the new images which ship with a full eMMC image
including a different MBR layout and a partition for U-Boot, because
our modern U-Boot can actually pass the command line to the kernel, and
the built-in one doesn't get used anyway.
Tested by upgrading from vendor OpenWrt to the current legacy image,
from legacy to itself, to the previous legacy layout, and then to
finally the full-system image.
This commit probably wants backporting to 19.07, which also doesn't
install over the vendor OpenWrt and doesn't even have a full-system
installation option.

This harmonizes the device node names (and thus the image names, too)
between subtargets of the mediatek target. So far, each subtarget
has somewhat used its own naming scheme. Now, we use the vendor_device
syntax there, too.
Since DTS names have different patterns and the target only contains
a few devices, this does not replace DEVICE_DTS by a calculated
default value (like for other targets).
SUPPORTED_DEVICES is adjusted based on the node rename where necessary,
though it looks like for several older devices it was not set up
correctly so far.
While at it, this also changes the DTS name for u7623-02-emmc-512m

This commit adds support for the MT7623A-based UniElec U7623-02 router,

The device has the following specifications:
* MT7623A (quad-core, 1.3 GHz)
* 512MB RAM (DDR3)
* 8GB storage (eMMC 4.5)
* 2x normal miniPCIe slots
* 1x miniPCIe slot that is connected via an internal USB OTG port
* 5x 1Gbps Ethernet (MT7530 switch)
* 1x UART header
* 1x USB 3.0 port
* 1x SATA 3.0
* 1x 40P*0.5mm FPC for MIPI LCD
* 1x SIM slot
* 12x LEDs (2 GPIO controlled)
* 1x reset button
* 1x DC jack for main power (12V)
The following has been tested and is working:
* Ethernet switch
* miniPCIe slots (tested with Wi-Fi cards)
* USB 3.0 port
* sysupgrade
* reset button
Not working:
* The miniPCIe connected via USB OTG. For the port to work, some MUSB
glue must be added. I am currently in the process of porting the glue
from the vendor SDK.
Not tested:
* SATA 3.0
* MIPI LCD
Installation:
The board ships with u-boot, and the first installation needs to be done
via the bootloader using tftp. Step number one is to update the MBR of
the eMMC, as the one that ships with the device is broken. Since the
device can ship with different storage sizes, I will not provide the
exact steps for creating a valid MBR. However, I have made some
assumptions about the disk layout - there must be one 8MB recovery
partition (FAT32) and a partition for the rootfs (Linux).
The board loads the kernel from block 0xA00 (2560) and I have reserved
32MB for the kernel (65536 blocks). I have aligned the partitions on the
erase block size (4096 byte), so the recovery partition must start on
block 69632 and end on 86016 (16385 sectors). The rootfs is assumed to
start on sector 90112.
In order to install the mbr, you run the following commands from the
u-boot command line:
* tftpboot ${loadaddr} <name of mbr file>
* mmc device 0
* mmc write ${loadaddr} 0x00 1
Run the following commands to install + boot OpenWRT:
* tftpboot ${loadaddr} openwrt-mediatek-mt7623-7623a-unielec-u7623-02-emmc-512m-squashfs-sysupgrade-emmc.bin.gz
* run boot_wr_img
* run boot_rd_img
* bootm
Recovery:
In order to recover the router, you need to follow the installation
steps above (no need to replace MBR).
Notes:
* F2FS is used as the overlay filesystem.
* The device does not ship with any valid MAC address, so a random
address has to be generated. As a work-around, I write the initial
random MAC to a file on the recovery partition. The MAC of the WAN
interface is set to the MAC-address contained in this file on each boot,
and the address of the LAN-interfaces are WAN + 1. The MAC file is kept
across sysupgrade/firstboot.
My approach is slightly different than what the stock image does. The
first fives bytes of the MAC addresses in the stock image are static,
and then the last byte is random. I believe it is better to create fully
random MAC addresses.
* In order to support the miniPCIe-slots, I needed to add missing
pcie-nodes to mt7623.dtsi. The nodes are just c&p from the upstream
dtsi.
* One of the USB3.0 phys (u3phy2) on the board can be used as either USB
or PCI, and one of the wifi-cards is connected to this phy. In order to
support switching the phy from USB to PCI, I needed to patch the
phy-driver. The patch is based on a rejected (at least last time I
checked) PCI-driver submitted to the linux-mediatek mailing list.
* The eMMC is configured to boot from the user area, and according to
the data sheet of the eMMC this value can't be changed.
* I tried to structure the MBR more nicely and use for example a
FAT32-parition for the kernel, so that we don't need to write/read from
some offset. The bootloader does not support reading from
FAT32-paritions. While the command (fatload) is there, it just throws an
error when I try to use it.
* I will submit and hope to get the DTS for the device accepted
upstream. If and when that happens, I will update the patches
accordingly.
