Convert the Enterasys WS-AP3710i access point to use the simpleImage
wrapper.
This is necessary, as the bootlaoder does not align the DTB correctly
(and does not support altering the FDT loadaddress). Booting images with
kernels 5.15 and later can break depending on the alignment on the DTB
within the FIT image.

with 6.1, the kernel no longer fitted into the 16 MiB and
kicking down the can and increasing KERNEL_SIZE to 20 MiB
didn't help as the device failed to boot.
Using 'kernel-bin | gzip | uimage gzip' didn't work since the
uboot does not have enough heap to decompress these big kernels.
And finally playing around with uboot was more a hassle than
converting this device to take the simpleImage-boot-route in
the future.
Note: The device now takes even longer on the first boot-up after
the flash due to JFFS2 initializing all the remaining flash.
Be prepared to wait up to 10 minutes before the green status LED
stops blinking and will shine a solid green!
(On the plus site: the device now has ~10 MiB of additional
space for rootfs+rootfs_data).
Note2: This patch includes a kernel patch refresh.

The boot-procedure for the Extreme WS-AP3825I is vfragile to put it
mildly. It does not relocate the FDT properly. It currently exercises
every step manually as well as coming with a pre-padded dtb.
Use the PowerPC bootwrapper code for legacy platforms with a pre-filles
DTS instead. We still need to ship a fit image to not break the fdt
resize / relocate instructions on existing boards. This does not require
adapting the U-Boot bootcommand.

In subtarget p2020, there wasn't enabled nand support, and because of
that there weren't available tools from mtd-utils package, which has
utilities for NAND flash memory even though reference board, which
is the only currently supported device in p2020 subtarget has NAND [1].
All subtargets in mpc85xx has already enabled nand support, let's do it
globally.

CPU: FSL P1020 (2x 800MHz E500 PPC)
RAM: 1GB DDR3
FLASH: 256MiB NAND
WiFi: 2x Atheros AR9382 2x2:2 abgn
ETH: 2x BCM54616S - 1x BCM53128 8-port switch
LED: 5x LEDs (Power, WiFi1, WiFi2, N/D, SYS)
BTN: 1x RESET
Installation
------------
1. Download initrams kernel image, dtb binary and sysupgrade image.
2. Place initramfs kernel into tftp root directory. Rename to
"panda-uimage-factory".
3. Place dtb binary into tftp root directory. Rename to "panda.fdt".
4. Start tftp server on 192.168.100.8/24.
5. Power up the device with the reset button pressed. It will download
the initrams and dtb via tftp and boot into OpenWRT in RAM.
6. SSH into the device and remove the factory partitions.
> ubirmvol /dev/ubi0 --name=kernel1
> ubirmvol /dev/ubi0 --name=rootfs1
> ubirmvol /dev/ubi0 --name=devicetree1
You will have around 60 MiB of free space with that.
You can also delete "kernel2", "devicetree2", "rootfs2" and "storage"
respectively in case you do not want to go back to the vendor firmware.
7. Modify the U-Boot bootcmd to allow for booting OpenWRT
> fw_setenv bootcmd_owrt "ubi part ubi && ubi read 0x1000000 kernel
&& bootm 0x1000000"
> fw_setenv bootargs_owrt "setenv bootargs console=ttyS0,115200
ubi.mtd=3,2048"
> fw_setenv bootcmd "run bootargs_owrt; run bootcmd_owrt"
8. Transfer the sysupgrade image via scp into the /tmp directory.
9. Upgrade the device
> sysupgrade -n /tmp/<imagename>

BTN: None
Installation
============
1. Power on the device while attached to the Console port.
2. Halt the U-Boot by pressing Enter when prompted.
3. Set the correct bootcmd for booting OpenWRT:
> setenv bootargs_owrt "setenv bootargs console=ttyS0,115200"
> setenv bootcmd "run bootargs_owrt;
nand read 0x1000000 0x300000 0x800000;
bootm 0x1000000;"
> saveenv
5. Rename OpenWRT initramfs image to 'kernel.bin' and place it in a
TFTP server root-directory served on 192.168.1.2/24. Connect your
computer to one of the LAN-ports.
4. Boot OpenWRT initramfs image with
> run bootargs_owrt; tftpboot 0x1000000 192.168.1.2:kernel.bin;
bootm 0x1000000;
6. (Optional)
Make a Backup of 'sophos-os1', 'sophos-os2' and 'sophos-data' in case
you ever want to go back to the vendor firmware.
7. Create Ubi Volume on mtd4 by executing
> ubiformat /dev/mtd4 -y
8. Transfer OpenWRT sysupgrade image to the device via SCP and install it
with
> sysupgrade -n <openwrt-image-file>
Back to Stock
=============
If you want to go back to the stock firmware, here is the bootcmd of the
vendor firmware:
> setenv bootargs console=ttyS0,115200 root=/dev/mtdblock5;
nand read 0xc00000 0x00300000 0x100000;
nand read 0x1000000 0x00400000 0x00800000;
bootm 0x1000000 - 0xc00000
Set it via 'setenv' from the U-Boot shell and don't forget to save it
using 'saveenv'!
After this, boot the OpenWRT initramfs image just like you would for
installation. Write back the three vendor partitions using mtd. Reboot
the device afterwards.
