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/product/rk3126c.json 用于指定编译rk3126c固件含哪些模块，这里删除了foundation相关仓库，保留hdf驱动以及liteos_a内核模块。

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

补丁打完后可通过build.py进行编译
build.py rk3126c
编译得到文件用于烧写：
out/rk3126c/liteos.bin
out/rk3126c/rootfs.img
重启设备进入liteos内核：

搞了好几天rv1126终于也起来了，遇到几个坑分享一下。
1. 参照https://harmonyos.51cto.com/posts/1318在鸿蒙的开发环境进行编译，可以正常编译。但是无法正确打包fit格式的uboot.img
具体原因也没仔细查，后来在瑞芯微原本的开发环境就可以正常编译并且生成正确的uboot.img
2. liteos启动以后只有汇编中输出的log:VCDEFGM，别的都没有。
调查发现是因为
kernel/liteos_a/shell/full/src/base/shell_lk.c
LK_FUNC g_osLkHook = (LK_FUNC)OsLkDefaultFunc;
默认不是NULL，所以导致执行PRINT_RELEASE("\nmain\n");的时候就出不去
另外如果只是单纯修改这个位置，无法正确进入OHOS。
暂时简单粗暴的把LOS_LkPrint的实现注释掉就可以顺利跳转了。
这份源码，怎么跟opeharminy1.0和2.0都不一样，请问这是哪个分支的源码
