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 - Signed-off-by: Daniel Danzberger <daniel@dd-wrt.com> |
