I think I've got it working....doing a full build now.
This is what I did:
1. mkdir /opt/buildroot/linux/kernel-patches
2. name patches in the order that you want them applied, for example:
root at prodvarm:/opt/buildroot/linux/kernel-patches# ls -1
linux-2.6.38-rc5-0001.patch
linux-2.6.38-rc5-0002.patch
linux-2.6.38-rc5-0003.patch
linux-2.6.38-rc5-0004.patch
linux-2.6.38-rc5-0005.patch
linux-2.6.38-rc5-0006.patch
3. Create a list of patches to paste into the "Custom patches" option when
running "make menuconfig":
root at prodvarm:/opt/buildroot# find linux/kernel-patches/ | grep "\.patch" |
sort -n | xargs
linux/kernel-patches/linux-2.6.38-rc5-0001.patch
linux/kernel-patches/linux-2.6.38-rc5-0002.patch
linux/kernel-patches/linux-2.6.38-rc5-0003.patch
linux/kernel-patches/linux-2.6.38-rc5-0004.patch
linux/kernel-patches/linux-2.6.38-rc5-0005.patch
linux/kernel-patches/linux-2.6.38-rc5-0006.patch
root at prodvarm:/opt/buildroot#
4. run "make menuconfig", then go to kernel/custom patches option and paste
the "patch list" like so:
linux/kernel-patches/linux-2.6.38-rc5-0001.patch
linux/kernel-patches/linux-2.6.38-rc5-0002.patch
linux/kernel-patches/linux-2.6.38-rc5-0003.patch
linux/kernel-patches/linux-2.6.38-rc5-0004.patch
linux/kernel-patches/linux-2.6.38-rc5-0005.patch
linux/kernel-patches/linux-2.6.38-rc5-0006.patch
5. Make sure previous kernel bits have been removed:
rm -rf output/toolchain/linux-2.6.38-rc5 ; rm
-rf output/build/linux-2.6.38-rc5
6. "make"
After a while you'll see it extracting the kernel and then applying the
patches....although I've not tried to boot the resulting uImage yet....but
my boards ".._defconfig" was there and the build appeared to go through.
Thanks for the help!!!
