Chao:
 Can you follow Mike's suggestion to share the your code change in your personal GitHub repo as the first step?

Thanks

LI Chao,

The best way to share your source code changes with the TianoCore

community

with a fork of the edk2 repository in your personal GitHub.  Create a branch

with the proposed changes and send an email with the link to the branch for

the community to review.

The edk2-staging repository would be a good second step if the new

architecture is approved for the EDK II project.

Best regards,

Mike

Hi LI Chao,

Can you provide a brief description of LoongArch and perhaps provide links

to

documentation and overview materials?

Thanks,

Mike

Subject: [edk2-devel] About how to submit a new architecture called

LoongArch

Dear All:

   I want to submit a new architecture called LoongArch on EDK2 and

the USWG recommands us do "code first" because the

UEFI specifitcation will easily accpet our arch.

   What can we do? Do I submit the part 1 code for new architecture on

the "staging" branch? Hop you reply. :)
