Hello,
Attached are two patches that should enable a CuBox device to be
supported by the CRUX-ARM git kernel and uboot.
You may read the procedure I follow (once these patches are applied)
here[0] to verify that I'm doing the right thing.
You may download a kernel tarball here[1] and a kernel config here[2] if
you are interested in hosting them in the CRUX-ARM distfiles. These are
not stored permanently at the moment though we can discuss something if
device maintainers will be expected to host their own files.
The original kernel sources are from
https://github.com/vDorst/linux/tree/CuBox-v3.5.3-Patched but there has
been activity in the repo since the snapshot was taken.
Testing has been light, since I've been unable to install a full
userspace. I've been using this kernel with my old install and I haven't
noticed any issues that could be attributed to the kernel.
I'm not sure what the policies for the kernel configs are - I tend to
use as few modules as possible and strip out support for things like USB
network adapters, which might be useful for people performing
installations. I've shipped it as-is.
Regards,
Ryan
