Hi,
v2:
fix cc tag so Rob can receive the patch
add oftree support to xgmac
The following patch serie add the support of the Quad Core Cortex-A9
Highbank from Calxeda
As I do not have the real hardware this is only tested on qemu
Rob could confirm if this work on real hw
This patch serie depends on the amba sp804 patch and the ahci patch serie
The following changes since commit ad65d793bbaccc4b97422c612322d3d9885c8cfd:
ahci: handle COMINIT received during spin-up (2013-02-11 07:45:37 +0800)
are available in the git repository at:
git://git.jcrosoft.org/barebox.git delivery/highbank

Hi,
The following patch serie add the support of the Quad Core Cortex-A9
Highbank from Calxeda
As I do not have the real hardware this is only tested on qemu
Rob could confirm if this work on real hw
This patch serie depends on the amba sp804 patch and the ahci patch serie
The following changes since commit ad65d793bbaccc4b97422c612322d3d9885c8cfd:
ahci: handle COMINIT received during spin-up (2013-02-11 07:45:37 +0800)
are available in the git repository at:
git://git.jcrosoft.org/barebox.git delivery/highbank
for you to fetch changes up to 4a7b1e47fb54662421ef78d20d2d873d1f12101b:
