airoha: Add new target platform
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
