use rpmbuild -bb yaboot-xcat.spec to make the build yaboot-xcat-1.3.17-rc1.noarch.rpm
Patchs overview:
These patches are no use now:
1. yaboot-skipmac.patch--done
This patch is used to skip using mac address in the configuration file.
Since the P775 will use the mac address in the configuration file, I think it is no use anymore.
2. yaboot-1.3.15-promclaim.patch
The newest official yaboot build has contained this patch.
3. yaboot-1.3.14-better_netboot.patch
The newest official yaboot build has contained this patch.
4. yaboot-1.3.14-ipv6.patch
The newest official yaboot build has contained this patch.
5. yaboot-fixes.patch
This patch was not used in the last xcat-yaboot build.
6. yaboot-1.3.14-better_netboot2.patch
The newest official yaboot build has contained this patch.
7. yaboot-1.3.14-move_kernel.patch
Free the TFTP load buffer so the booted kernel has some memory to run with. It is no use for 3.17-rc1 yaboot build.
These patches will be used in the new build.
1. yaboot-32bitbuild.patch
Add the "-m32" compiler switch to tell GCC to compile user code as 32-bit.
2. yaboot-sanedhcppriority.patch
Use the mask and gateway from bootp package to overwrite the existed boot-path.
I've no idea about the reason of this patch, and don't think it is a necessary patch but still leave it here.
New patches:
1. yaboot-promclaim.patch
Claime big size on pROM for the large initrd file.
2. yaboot-debug.patch
This patch adds some print and enable the debug information in yaboot, used to debug problems.
