Due to issues surrounding the implementation of the vendor BMT/BBT
on Airoha, upstream ATF + uboot has switched to UBI flash partitions.
However, some devices shipped on this platform are bootloader locked,
and thus it is impossible to replace ATF + uboot.
During testing for the Gemtek W1700K (#17869), sysupgrades from Linux
(which is unaware of the underlying BMT/BBT) would occasionally write
data into blocks which were remapped by the vendor uboot when it was
read on the following reboot, causing a soft brick.
An acceptable workaround [1],[2] was discussed where an intermediate
uboot would be written by the vendor uboot (which is aware of Airoha
BMT/BBT). This chainloader would then ignore the regions of flash
used by the vendor uboot, and store all relevant data inside of UBI.
UBI would then be used to handle bad block management. As the vendor
ATF + uboot do not read or interact with the UBI region, we would avoid
unwanted remaps from BMT/BBT.
This commit introduces support for building such a chainloader, by
packaging u-boot and DTS into a FIT image; to be flashed like a kernel.
Configuration for the Gemtek W1700K is provided as an example of how the
chainloader is used.

Similar to e92b153e99 ("mediatek: introduce KERNEL_LOADADDR to Device/Default template"),
let's move the default loadaddr to Device/Default.
What's more, use 0x80200000 instead of the SDK default value 0x80088000
to avoid the following error which may overwrite TZ memory and cause crash:
[ 0.000000] [Firmware Bug]: Kernel image misaligned at boot, please fix your bootloader!
[ 0.000000] OF: reserved mem: Reserved memory: failed to reserve memory for node 'atf@80000000': base 0x0000000080000000, size 2 MiB

Pack the BL2 and BL31+U-Boot artifacts as Airoha AN7581 is currently
supported in upstream U-Boot and bootloader files can be used for
unfused boards.

Fix the current image Makefile for Airoha AN7583 by dropping the
artifacts entry for bootloader and add default PKG for the PHY mounted
on the RFB boards.
The artifacts for the bootloader will be readded later once ATF-A
support will be pushed mainline.

This option will only take effect when the "separate_ramdisk"
feature was enabled. However, this target does not support
this feature. It is an obvious copy and paste issue.

All devices under airoha use dts directory under the target,
so update the default DEVICE_DTS_DIR. Also set the default
DEVICE_DTS based on the SoC name for non-dev boards.

Introduce initial support for Airoha AN7583 SoC and add all the required
patch for basic functionality of the SoC.
Airoha AN7583 is based on Airoha EN7581 SoC with some major changes on
the PHY handling and Serdes. It can be see as a lower spec of EN7581
with modern and simplified implementations.
All the patch are sent upstream and are pending revision. Support for
PCIe and USB will come later as soon as DT structure is accepted
upstream.

Introduce EN7581 SoC support with currently rfb board supported.
This is a new 64bit SoC from Airoha that is currently almost fully
supported upstream with only the DTS missing. Setting source-only
waiting for the full upstream support to be completed.

In preparation for EN7581 SoC support, move en7523 in dedicated
subtarget.
This is needed as EN7581 is now 64bit but en7523 is 32bit hence have
very different kernel config.
Also rename patch to a more friendly number sequence.

Airoha is a new ARM platform based on Cortex-A53 which has recently been
merged into linux-next.
Due to BootROM limitations on this platform, the Cortex-A53 can't run in
Aarch64 mode and code must be compiled for 32-Bit ARM.
This support is based mostly on those linux-next commits backported
for kernel 5.15.
Patches:
1 - platform support = linux-next
2 - clock driver = linux-next
3 - gpio driver = linux-next
4 - linux,usable-memory-range dts support = linux-next
5 - mtd spinand driver
6 - spi driver
7 - pci driver (kconfig only, uses mediatek PCI) = linux-next
Still missing:
- Ethernet driver
- Sysupgrade support
A.t.m there exists one subtarget EN7523 with only one evaluation
board.
The initramfs can be run with the following commands from u-boot:
-
u-boot> setenv bootfile \
openwrt-airoha-airoha_en7523-evb-initramfs-kernel.bin
u-boot> tftpboot
u-boot> bootm 0x81800000
