Support for LINUX Boot
To enable/disable feature, PcdLinuxBootEnable can be used
1. Follow directions on http://osresearch.net/Building/ to compile the heads kernel and initrd for qemu-system_x86_64
2. Copy the following built files
(1) initrd.cpio.xz to PurleyOpenBoardPkg/Features/LinuxBoot/LinuxBinaries/initrd.cpio.xz
(2) bzimage to PurleyOpenBoardPkg/Features/LinuxBoot/LinuxBinaries/linux.efi
Notes:
V2 :
- Rename LinuxBootPkg to LinuxBoot
- Move LinuxBootPkg to PurleyOpenBoardPkg/Features/LinuxBoot
- Follow Coding Standard in LinuxBoot.C and LinuxBoot.h

Subject: [edk2-platforms][PATCH V2] PurleyOpenBoardPkg : Support for LINUX Boot
Support for LINUX Boot
To enable/disable feature, PcdLinuxBootEnable can be used
1. Follow directions on http://osresearch.net/Building/ to compile the heads kernel and initrd for qemu-system_x86_64
2. Copy the following built files
(1) initrd.cpio.xz to PurleyOpenBoardPkg/Features/LinuxBoot/LinuxBinaries/initrd.cpio.xz
(2) bzimage to PurleyOpenBoardPkg/Features/LinuxBoot/LinuxBinaries/linux.efi
Notes:
V2 :
- Rename LinuxBootPkg to LinuxBoot
- Move LinuxBootPkg to PurleyOpenBoardPkg/Features/LinuxBoot
- Follow Coding Standard in LinuxBoot.C and LinuxBoot.h

Hi Manic,
Unfortunately this patch cannot be merged as is. It appears to contain a pre-built binary of the Linux kernel that has been pre-configured for Linuxboot use. While this is very convenient, the Linux kernel is licensed under the GPL and hence we cannot add it to edk2-platforms, which must be kept as BSD only. It might be possible to add this to edk2-non-osi, but even then we would require that you provide a readme file that explains how to get and compile the source code that you used to build this exact Linux image, as required by the GPL.
The easiest and safest option would be to remove the Linux binary all together and provide instructions to the user for how to build their own image and add it to the tree.
Thanks,
Nate

Nate :
If you see in this patch, linux.efi/initrd.cpio.xz are dummy files. These dummy files needs to be replaced by building the Linux Kernel.
How to build Linux Kernel is mentioned in the ReadMe document which is part of this patch.
1. Follow directions on http://osresearch.net/Building/ to compile the heads kernel and initrd for qemu-system_x86_64
2. Copy the following built files
(1) initrd.cpio.xz to LinuxBootPkg/LinuxBinaries/initrd.cpio.xz
(2) bzimage to LinuxBootPkg/LinuxBinaries/linux.efi
Thank you
-Manic

**CAUTION: The e-mail below is from an external source. Please exercise caution before opening attachments, clicking links, or following guidance.**
Hi Manic,
Unfortunately this patch cannot be merged as is. It appears to contain a pre-built binary of the Linux kernel that has been pre-configured for Linuxboot use. While this is very convenient, the Linux kernel is licensed under the GPL and hence we cannot add it to edk2-platforms, which must be kept as BSD only. It might be possible to add this to edk2-non-osi, but even then we would require that you provide a readme file that explains how to get and compile the source code that you used to build this exact Linux image, as required by the GPL.
The easiest and safest option would be to remove the Linux binary all together and provide instructions to the user for how to build their own image and add it to the tree.
Thanks,
Nate

Hi Manic,
That is fair. I see your new patch which add a readme.md explaining that. With that...

Subject: RE: [EXTERNAL] RE: [edk2-platforms][PATCH V2] PurleyOpenBoardPkg : Support for LINUX Boot
Nate :
If you see in this patch, linux.efi/initrd.cpio.xz are dummy files. These dummy files needs to be replaced by building the Linux Kernel.
How to build Linux Kernel is mentioned in the ReadMe document which is part of this patch.
1. Follow directions on http://osresearch.net/Building/ to compile the heads kernel and initrd for qemu-system_x86_64
2. Copy the following built files
(1) initrd.cpio.xz to LinuxBootPkg/LinuxBinaries/initrd.cpio.xz
(2) bzimage to LinuxBootPkg/LinuxBinaries/linux.efi
Thank you

**CAUTION: The e-mail below is from an external source. Please exercise caution before opening attachments, clicking links, or following guidance.**
Hi Manic,
Unfortunately this patch cannot be merged as is. It appears to contain a pre-built binary of the Linux kernel that has been pre-configured for Linuxboot use. While this is very convenient, the Linux kernel is licensed under the GPL and hence we cannot add it to edk2-platforms, which must be kept as BSD only. It might be possible to add this to edk2-non-osi, but even then we would require that you provide a readme file that explains how to get and compile the source code that you used to build this exact Linux image, as required by the GPL.
The easiest and safest option would be to remove the Linux binary all together and provide instructions to the user for how to build their own image and add it to the tree.
Thanks,
Nate

Subject: RE: [EXTERNAL] RE: [edk2-platforms][PATCH V2] PurleyOpenBoardPkg : Support for LINUX Boot
Nate :
If you see in this patch, linux.efi/initrd.cpio.xz are dummy files. These dummy files needs to be replaced by building the Linux Kernel.
How to build Linux Kernel is mentioned in the ReadMe document which is part of this patch.
1. Follow directions on http://osresearch.net/Building/ to compile the heads kernel and initrd for qemu-system_x86_64
2. Copy the following built files
(1) initrd.cpio.xz to LinuxBootPkg/LinuxBinaries/initrd.cpio.xz
(2) bzimage to LinuxBootPkg/LinuxBinaries/linux.efi
Thank you
-Manic

**CAUTION: The e-mail below is from an external source. Please exercise caution before opening attachments, clicking links, or following guidance.**
Hi Manic,
Unfortunately this patch cannot be merged as is. It appears to contain a pre-built binary of the Linux kernel that has been pre-configured for Linuxboot use. While this is very convenient, the Linux kernel is licensed under the GPL and hence we cannot add it to edk2-platforms, which must be kept as BSD only. It might be possible to add this to edk2-non-osi, but even then we would require that you provide a readme file that explains how to get and compile the source code that you used to build this exact Linux image, as required by the GPL.
The easiest and safest option would be to remove the Linux binary all together and provide instructions to the user for how to build their own image and add it to the tree.
Thanks,
Nate
