给大家分享瑞芯微三款A7芯片liteos_a内核补丁，打上附件补丁编译可进入鸿蒙内核。

补丁主要涉及四个目录：

build/lite/

kernel/liteos_a/

drivers/hdf/lite/

vendor/rockchip/

1.build/lite/

该目录修改添加新的product 的编译支持，修改和添加下列文件文件：

project build/lite/

-m build.py

-- config/boards/rk3126c.gni

-- config/boards/rk3288.gni

-- config/boards/rv1126.gni

-m gen_rootfs.py

-- product/rk3126c.json

-- product/rk3288.json

-- product/rv1126.json

修改build.py和gen_rootfs.py两处修改用于支持build.py rk3126c编译命令和生成vfat格式的rootfs.img。

build/lite/config/boards/rk3126c.gni指定芯片对应指令集rk3126c对应cortex-a7

board_arch = "armv7-a"

board_cpu = "cortex-a7"

2.kernel/liteos_a

主要添加芯片对应的内核配置文件如：rk3126c_clang_release.config，添加修改文件如下：

project kernel/liteos_a/

-m Kconfig

-m Makefile

-m arch/arm/arm/src/startup/reset_vector_up.S

-m fs/vfs/vfs_cmd/vfs_shellcmd.c

新增编译内核的config配置文件tools/build/config/rk3126c_clang_release.config， 添加宏LOSCFG_PLATFORM_RK3126C=y和LOSCFG_PLATFORM="rk3126c"支持区分新的芯片编译
