[PATCH 3/3] ARM: aspeed: Add secure boot controller support

[kernel test robot]

Hi Joel,

I love your patch! Perhaps something to improve:

[auto build test WARNING on robh/for-next]
[also build test WARNING on soc/for-next rockchip/for-next shawnguo/for-next v5.16-rc2 next-20211125]
[cannot apply to arm/for-next arm64/for-next/core]
[If your patch is applied to the wrong git tree, kindly drop us a note.
And when submitting patch, we suggest to use '--base' as documented in
