Hi Niu,
You need to split the patch, and prepare a cover letter..
Have to say, generally, this patch isn't really different comparing
with current in tree bananapi-f3, so neither it is useful..
I personally would expect to see more drivers support for K1 SoC,
then figure out how to have more boards enabled..
(I'd propose to not merge this patch, but if maintainer is ok with
this, then I'd have no objection)

this brings some confusions, as currently there is no SD/eMMC driver support
for K1, only means it's able to boot from SD/eMMC (with brom support)

I haven't checked the config, but compare to bananapi-f3_defconfig,
it's more less options than it, please make sure all necessary drivers
included..

there is a prerequisite to prepare all the partitions, so need to flash with

I'd personally rather have a file specific macro..
but it seems quite common to use this macro, so I will
