From f32085fc0b87049491b07e198d924d738a1a2834 Mon Sep 17 00:00:00 2001 From: Daniel Danzberger Date: Wed, 3 Aug 2022 17:31:03 +0200 Subject: 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 - Signed-off-by: Daniel Danzberger --- target/linux/airoha/Makefile | 15 +++++++++++++++ 1 file changed, 15 insertions(+) create mode 100644 target/linux/airoha/Makefile (limited to 'target/linux/airoha/Makefile') diff --git a/target/linux/airoha/Makefile b/target/linux/airoha/Makefile new file mode 100644 index 0000000000..723bec8cd4 --- /dev/null +++ b/target/linux/airoha/Makefile @@ -0,0 +1,15 @@ +include $(TOPDIR)/rules.mk + +ARCH:=arm +BOARD:=airoha +BOARDNAME:=Airoha ARM +CPU_TYPE:=cortex-a7 +FEATURES:=dt squashfs nand ramdisk gpio source-only + +KERNEL_PATCHVER:=5.15 + +include $(INCLUDE_DIR)/target.mk + +KERNELNAME:=Image dtbs + +$(eval $(call BuildTarget)) -- cgit v1.2.3
