Re: [edk2-devel] [PATCH v3 1/4] UefiPayloadPkg: Add LINUXBOOT payload target

Posted by Ni, Ray 4 years, 5 months ago

Can you describe how LINUXBOOT payload is supported in the commit message?
One line commit message is too simple for such a big feature😊

Re: [edk2-devel] [PATCH v3 1/4] UefiPayloadPkg: Add LINUXBOOT payload target

Posted by Guo Dong 4 years, 4 months ago

Hi Ray,

I had updated the patch to update the commit message and fix some coding style.
Please help review V4 patch.

Thanks,
Guo

Subject: RE: [PATCH v3 1/4] UefiPayloadPkg: Add LINUXBOOT payload target

Can you describe how LINUXBOOT payload is supported in the commit message?
One line commit message is too simple for such a big feature😊
