Re: On integrating LoongArch EDK2 firmware into QEMU build process

[Chao Li]

Hi Xuerui,

    Sorry for late reply. In fact the EDK2 repo is ready for submit, in a few days I will commit the patch set in kilaterlee/edk2 repo and execute the EDK2 CI testing. I will notify some people to review them, you are also welcome to review the patch set. And then, I'll submit the formal version patch to the EDK2 devel community.

Thanks,
Chao
