Hardware
--------
SOC: MediaTek MT7988A (4x Cortex-A73)
RAM: 4 GiB DDR4
Flash: 128 MiB Winbond SPI-NAND
MMC: 8 GiB eMMC *or* microSD (cannot be used both)
ETH: 4x 1GE (1x WAN, 3x LAN)
2x SFP+ (10G, 5G, 2.5G, 1G)
USB: on-board USB 3.2 4-port hub
1x USB 3.2 port (type A connector)
1x M.2 for 4G/5G modem
2x mPCIe for additional modems
WiFi: optional MediaTek MT7996 Wi-Fi 7 module
(using 2x PCIe gen3 x2 on the mPCIe slots and 12V power)
Installation
------------
1. Decompress and write the sdcard image to a micro SD card and use that
to boot the R4 (both dip switches in upper position).
2. Use the bootloader menu accessible via the serial console to install
to SPI-NAND.
3. Switch to boot from SPI-NAND and install to eMMC.

Add 'fitblk' driver to replace the rejected/deprecated uImage.FIT
partition parser.
To use the new driver, add phandle /chosen/rootdisk and point it to
the MTD partition, UBI volume or block device holding the uImage.FIT.

In order to allow gradually migrating the boards currently using the
uImage.FIT partition (deprecated/rejected) parser to the new fitblk
driver, skip the partition parser code in case the new fitblk driver
(which serves the same purpose) is used.
As an indicator for the use of the new fitblk driver, check if the
/chosen/rootdisk property is present in the Device Tree.

The partition parser approach has been rejected upstream, it will be
replaced by a small block driver which is the solution suggestion by
upstream maintainers.
As the partition parser has only been used by the mediatek target, as
a first step, move it there.

Backport initial LEDs hw control support. Currently this is limited to
only rx/tx and link events for the netdev trigger but the API got
accepted and the additional modes are working on and will be backported
later.
Refresh every patch and add the additional config flag for QCA8K new
LEDs support.

UARTs not used as boot console are currently broken on some MediaTek
targets due to register access depending on the bus clock being enabled.
Add patch to make sure this dependency is always met.

Prior to performing a PROGRAM LOAD RANDOM DATA operation, a WRITE
ENABLE (06h) command must be issued to change the contents of the
memory array. Following a WRITE ENABLE (06) command, **first a PROGRAM
LOAD (02h or 32h) command must be issued to reset the cache**, then
issue a PROGRAM LOAD RANDOM DATA (84h or 34h) command
This is dirty fix provided to use by MediaTek engineer Sky Huang which
may resolve the "OpenWrt Kiss of Death" issue we've been seeing on the
Linksys E8450 aka. Belkin RT3200. However, it means that everything has
to be re-written with that patch already applied, ie. we need to rebuild
the installer once it is part of snapshot builds to have any effect.
Users already on FIP-in-UBI layout are advised to re-write 'fip' UBI
volume and 'bl2' MTD partition manually once from within Linux after
this fix has been applied.
A similar fix will also be required for U-Boot.

This adds the legacy /dev/fb* device file for kernel 6.6 again.
Linux upstream commit 701d2054fa31 ("fbdev: Make support for
userspace interfaces configurable") made this configurable and we
deactivated this option by default for kernel 6.6. On x86 we are
not space constrained and some users need this legacy interface.

The SPI max frequency was set to 80MHz, considerably higher than the
vendor clocks it in their firmware (10MHz). Multiple users reported
jffs2 corruption/instability.
My unit has a W25Q256; datasheet specifies maximum SPI frequency for
read command of 50MHz.
