Subject: [PATCH] mtd: spinand: Add support for Etron EM73D044VCx
|
|
|
|
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
|
|
