If you are OK with that, I feel that patches 1-6 and 9-10 are ready to
be merged.
I would like to discuss 7/10 to see if we can improve the readability
of the code, based on the additional information you provided.
(And I think there is no point to include 8/10 without 7/10?)
Best Regards,
Leif

Hi Leif,
Thank you for your reply！
I think your suggestion is very good. There is no dependency between patches 8 / 10 and 7 / 10.
I think it would be great if we could merge. For patch 7, Please point out what can be changed better， I will modify it according to your suggestions.
Best Regards,
Ling

Building with 8/10 but without 7/10 fails with
edk2-platforms/Silicon/Phytium/PhytiumCommonPkg/Drivers/FlashFvbDxe/FlashFvbDxe.inf(61):
error 4000: Value of [gSpiNorFlashProtocolGuid] is not found in
/work/git/edk2/EmbeddedPkg/EmbeddedPkg.dec

/work/git/edk2/MdeModulePkg/MdeModulePkg.dec
/work/git/edk2-platforms/Silicon/Phytium/PhytiumCommonPkg/PhytiumCommonPkg.dec
So I have pushed 1-6,9-10/10 as 7872c983ed45..0d85d9ceb01c. Thanks!

Yes, I will have a think and re-read the code with your explanation
and get back to you.
