This adds a full eMMC image including U-Boot, which means that the
kernel can inherit the true RAM size detected by the preloader.
As implemented in previous commits, sysupgrade to this image from
the legacy layout (and via that, from the vendor-installed image)
is supported.
Rename the legacy image for the 512MiB board, for clarity.

As I buy more hardware and continue to work on consolidation, This will
apply to a lot of MediaTek platforms; rename it accordingly.

This actually covers fairly much all the MediaTek platforms; they
only have different images because they don't include the preloader
and U-Boot, and rely on preinstalled stuff from the vendor.
So this script can slowly take over the world as we complete the
support for various other platforms, starting with UniElec U7623…

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.

bpi-r2 images are shipped with mainline u-boot which can extract lzma
with no problem.
remove custom kernel recipe to build lzma fit image instead of
uncompressed fit with zboot.

The current condition with part of the variables set dependent on
the subtarget in Device/Default isn't really nice to read and also
defeats the purpose of having a default node.
This removes the special settings for mt7623 and moves them to the
individual devices, which is not much of a problem as there are
actually just two of them and they partly use different settings
anyway.
While at it, slightly adjust the order of variables and wrap some
long lines.

The MT7623 SoC has the same SATA block as the MT7622, so enable it in
MT7623 builds too and add it to the DEVICE_PACKAGES for those boards.

The supported MT7623 boards are mostly identical (what with being a
System-on-Chip and all), so unify the DEVICE_PACKAGES for them, and add
ext4 and usb support for them.

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
to all-lower-case.

This commit adds support for the MT7623A-based UniElec U7623-02 router,
with eMMC storage and 512MB RAM. The router can be delivered with NAND
Flash and more memory, but I only have access to the one configuration.
The DTS is structured in such a way that adding support for
more/different storage/memory should be straight forward.
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.
