Looks good. I like the name.

Can you use scripts/get_maintainers.pl to send the next version to the
appropriate upstream lists?

Some review comments below.

Update your git config and re-generate the commit:

git config --global user.name "Chen PJ"
git commit --amend --reset-author

Obviously adjust the name to be whatever you want to be referred to in
the kernel commit logs.

This isn't something our kernels support. Did you test this with an
openbmc or mainline kernel?

This layout looks like the openbmc layout we have in the tree. You
should be able to do #include openbmc-flash-layout.dtsi or similar.

The board file gets these from ast2600-g6.dtsi, you don't need to
re-specify them here.
