The Airoha EN7581 got renamed to AN7581 due to move from Econet to
Airoha.
To save on compatibility, use both compatible for the device.

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
