ath79/tiny kernel config has
CONFIG_MTD_SPI_NOR_USE_4K_SECTORS=y
from commit
05d35403b2
Because of this, these changes are required for 2 reasons:
1.
Senao devices in ath79/tiny
with a 'failsafe' partition and the tar.gz sysupgrade platform
and a flash chip that supports 4k sectors
will fail to reboot to openwrt after a sysupgrade.
the stored checksum is made with the 64k blocksize length
of the image to be flashed,
and the actual checksum changes after flashing due to JFFS2 space
being formatted within the length of the rootfs from the image
example:
0x440000 length of kernel + rootfs (from sysupgrade.bin)
0x439000 offset of rootfs_data (from kernel log)
2.
for boards with flash chips that support 4k sectors:
saving configuration over sysupgrade is not possible
because sysupgrade.tgz is appended at a 64k boundary
and the mtd parser starts JFFS2 at a 4k boundary.
for boards with flash chips that do not support 4k sectors:
partitioning with 4k boundaries causes a boot loop
from the mtd parser not finding kernel and rootfs.
Also:
Some of the Senao boards that belong in ath79/tiny,
for example ENH202,
have a flash chip that does not support 4k sectors
(no SECT_4K symbol in upstream source).
Because of this, partitioning must be different for these devices
depending on the flash chip model detected by the kernel.
Therefore:
this creates 2 DTSI files
to replace the single one with 64k partitioning
for 4k and 64k partitioning respectively.

This creates a shared DTSI for ar724x Senao/Engenius APs:
- ENH202 v1
- EAP350 v1
- ECB350 v1
Since ar7240/ar7242 have different configuration, this new file
mostly contains the partitioning.

The uart node is enabled on all devices except one (GL-USB150 *).
Thus, let's not have a few hundred nodes to enable it, but do not
disable it in the first place.
Where the majority of devices is using it, also move the serial0
alias to the DTSI.
*) Since GL-USB150 even defines serial0 alias, the missing uart
is probably just a mistake. Anyway, disable it for now so this
patch stays cosmetic.

The only difference between the "openwrt,okli" and the generic
parser is the magic. Set this in device tree for all affected
devices and remove the "openwrt,okli" parser.

A few devices in ath79 and ramips use mtd-concat to concatenate
individual partitions into a bigger "firmware" or "ubi" partition.
However, the original partitions are still present and visible,
and one can write to them directly although this might break the
actual virtual, concatenated partition.
As we cannot do much about the former, let's at least choose more
descriptive names than just "firmwareX" in order to indicate the
concatenation to the user. He might be less tempted into overwriting
a "fwconcat1" than a "firmware1", which might be perceived as an
alternate firmware for dual boot etc.
This applies the new naming consistently for all relevant devices,
i.e. fwconcatX for virtual "firmware" members and ubiconcatX for
"ubi" members.
While at it, use DT labels and label property consistently, and
also use consistent zero-based indexing.

FCC ID: U2M-EAP350
Engenius EAP350 is a wireless access point with 1 gigabit PoE ethernet port,
2.4 GHz wireless, external ethernet switch, and 2 internal antennas.
Specification:
- AR7242 SOC
- AR9283 WLAN (2.4 GHz, 2x2, PCIe on-board)
- AR8035-A switch (GbE with 802.3af PoE)
- 40 MHz reference clock
- 8 MB FLASH MX25L6406E
- 32 MB RAM EM6AA160TSA-5G
- UART at J2 (populated)
- 3 LEDs, 1 button (power, eth, 2.4 GHz) (reset)
- 2 internal antennas
MAC addresses:
MAC address is labeled as "MAC"
Only 1 address on label and in flash
The OEM software reports these MACs for the ifconfig
eth0 MAC *:0c art 0x0
phy0 --- *:0d ---
Installation:
2 ways to flash factory.bin from OEM:
- if you get Failsafe Mode from failed flash:
only use it to flash Original firmware from Engenius
or risk kernel loop or halt which requires serial cable
Method 1: Firmware upgrade page:
OEM webpage at 192.168.10.1
username and password "admin"
Navigate to "Upgrade Firmware" page from left pane
Click Browse and select the factory.bin image
Upload and verify checksum
Click Continue to confirm and wait 3 minutes
Method 2: Serial to load Failsafe webpage:
After connecting to serial console and rebooting...
Interrupt uboot with any key pressed rapidly
execute `run failsafe_boot` OR `bootm 0x9f670000`
wait a minute
connect to ethernet and navigate to
"192.168.1.1/index.htm"
Select the factory.bin image and upload
wait about 3 minutes
Return to OEM:
If you have a serial cable, see Serial Failsafe instructions
otherwise, uboot-env can be used to make uboot load the failsafe image
*DISCLAIMER*
The Failsafe image is unique to Engenius boards.
If the failsafe image is missing or damaged this will not work
DO NOT downgrade to ar71xx this way, it can cause kernel loop or halt
ssh into openwrt and run
`fw_setenv rootfs_checksum 0`
reboot, wait 3 minutes
connect to ethernet and navigate to 192.168.1.1/index.htm
select OEM firmware image from Engenius and click upgrade
Format of OEM firmware image:
The OEM software of EAP350 is a heavily modified version
of Openwrt Kamikaze. One of the many modifications
is to the sysupgrade program. Image verification is performed
simply by the successful ungzip and untar of the supplied file
and name check and header verification of the resulting contents.
To form a factory.bin that is accepted by OEM Openwrt build,
the kernel and rootfs must have specific names...
openwrt-senao-eap350-uImage-lzma.bin
openwrt-senao-eap350-root.squashfs
and begin with the respective headers (uImage, squashfs).
Then the files must be tarballed and gzipped.
The resulting binary is actually a tar.gz file in disguise.
This can be verified by using binwalk on the OEM firmware images,
ungzipping then untaring.
The OEM upgrade script is at /etc/fwupgrade.sh
Later models in the EAP series likely have a different platform
and the upgrade and image verification process differs.
OKLI kernel loader is required because the OEM software
expects the kernel to be no greater than 1024k
and the factory.bin upgrade procedure would
overwrite part of the kernel when writing rootfs.
Note on PLL-data cells:
The default PLL register values will not work
because of the external AR8035-A switch between
the SOC and the ethernet PHY chips.
For AR724x series, the PLL register for GMAC0
can be seen in the DTSI as 0x2c.
Therefore the PLL register can be read from uboot
for each link speed after attempting tftpboot
or another network action using that link speed
with `md 0x1805002c 1`.
uboot did not have a good value for 1 GBps
so it was taken from other similar DTS file.
Tested from master, all link speeds functional
