sysupgrade-nand: allow limiting rootfs_data by setting env variable
Check if firmware environment variable 'rootfs_data_max' exists and is
set to a numerical value greater than 0. If so, limit rootfs_data
volume to that size instead of using the maximum available size.
This is useful on devices with lots of flash where users may want to
have eg. a volume for persistent logs and statistics or for external
applications/containers. Persistence on rootfs overlay is limited by
the size of memory available during the sysugprade process as that
data needs to be copied to RAM while the volume is being recreated
during sysupgrade. Hence it is unsuitable for keeping larger amounts
of data accross upgrade which makes additional volume(s) for
application data desirable.

image: allow building FIT and uImage with ramdisk
Instead of embedding the initrd cpio archive into the kernel, allow
for having an external ramdisk added to the FIT or uImage.
This is useful to overcome kernel size limitations present in many
stock bootloaders, as the ramdisk is then loaded seperately and doesn't
add to the kernel size. Hence we can have larger ramdisks to host ie.
installers with all binaries to flash included (or a web-based

image: add support for building FIT image with filesystem
Allow for single (external-data) FIT image to hold kernel, dtb and
squashfs. In that way, the bootloader verifies the system integrity
including the rootfs, because what's the point of checking that the
hash of the kernel is correct if it won't boot in case of squashfs
being corrupted? Better allow bootloader to check everything needed
to make it at least up to failsafe mode. As a positive side effect
this change also makes the sysupgrade process on nand potentially
much easier as it is now.
In short: mkimage has a parameter '-E' which allows generating FIT
images with 'external' data rather than embedding the data into the
device-tree blob itself. In this way, the FIT structure itself remains
small and can be parsed easily (rather than having to page around
megabytes of image content). This patch makes use of that and adds
support for adding sub-images of type 'filesystem' which are used to
store the squashfs. Now U-Boot can verify the whole OS and the new
partition parsers added in the Linux kernel can detect the filesystem
sub-images, create partitions for them, and select the active rootfs
volume based on the configuration in FIT (passing configuration via
device tree could be implemented easily at a later stage).
This new FIT partition parser works for NOR flash (on top of mtdblock),
NAND flash (on top of ubiblock) as well as classic block devices
(ie. eMMC, SDcard, SATA, NVME, ...).
It could even be used to mount such FIT images via `losetup -P` on a
user PC if this patch gets included in Linux upstream one day ;)

The switch may generate an "ATU violation" warning when a client moves

ramips: mt7621: add TP-Link EAP235-Wall support
The TP-Link EAP235-Wall is a wall-mounted, PoE-powered AC1200 access
point with four gigabit ethernet ports.
When connecting to the device's serial port, it is strongly advised to
use an isolated UART adapter. This prevents linking different power
domains created by the PoE power supply, which may damage your devices.
The device's U-Boot supports saving modified environments with
`saveenv`. However, there is no u-boot-env partition, and saving
modifications will cause the partition table to be overwritten. This is
not an issue for running OpenWrt, but will prevent the vendor FW from
functioning properly.
Device specifications:
* SoC: MT7621DAT
* RAM: 128MiB
* Flash: 16MiB SPI-NOR
* Wireless 2.4GHz (MT7603EN): b/g/n, 2x2
* Wireless 5GHz (MT7613BEN): a/n/ac, 2x2
* Ethernet: 4× GbE
* Back side: ETH0, PoE PD port
* Bottom side: ETH1, ETH2, ETH3
* Single white device LED
* LED button, reset button (available for failsafe)
* PoE pass-through on port ETH3 (enabled with GPIO)
Datasheet of the flash chip specifies a maximum frequency of 33MHz, but
that didn't work. 20MHz gives no errors with reading (flash dump) or
writing (sysupgrade).
Device mac addresses:
Stock firmware uses the same MAC address for ethernet (on device label)
and 2.4GHz wireless. The 5GHz wireless address is incremented by one.
This address is stored in the 'info' ('default-mac') partition at an
offset of 8 bytes.
From OEM ifconfig:
eth a4:2b:b0:...:88
ra0 a4:2b:b0:...:88
rai0 a4:2b:b0:...:89
Flashing instructions:
* Enable SSH in the web interface, and SSH into the target device
* run `cliclientd stopcs`, this should return "success"
* upload the factory image via the web interface
Debricking:
U-boot can be interrupted during boot, serial console is 57600 baud, 8n1
This allows installing a sysupgrade image, or fixing the device in
another way.
* Access serial header from the side of the board, close to ETH3,
pin-out is (1:TX, 2:RX, 3:GND, 4:3.3V), with pin 1 closest to ETH3.
* Interrupt bootloader by holding '4' during boot, which drops the
bootloader into its shell
* Change default 'serverip' and 'ipaddr' variables (optional)
* Download initramfs with `tftpboot`, and boot image with `bootm`
# tftpboot 84000000 openwrt-initramfs.bin
