HI,
v3: rebase on the v3 of at91sam9xek i2c support
with this +1 patch serie the support of the at91sam9x5ek is mostly
complete
This will add spi and mci0 support as spi0 and mci0 conflict
We are still missing framebuffer, usb host and device and hardware i2c support
but this wil be added later
This patch serie depedsn on the at91sam9x5ek i2c and m25p80 patcheries
the correct version
this one work but brake the etherent as it mux the 4 cs as gpio and we
use them on the eth0
The following changes since commit b3a0963d358e14180e9bbde68ab78fdebae071b7:
m25p80: sync flash support with the kernel (2012-11-03 04:23:15 +0800)

HI,
with this +1 patch serie the support of the at91sam9x5ek is mostly
complete
This will add spi and mci0 support as spi0 and mci0 conflict
We are still missing framebuffer, usb host and device and hardware i2c support
but this wil be added later
This patch serie depedsn on the at91sam9x5ek i2c and m25p80 patcheries
the correct version
this one work but brake the etherent as it mux the 4 cs as gpio and we
use them on the eth0
The following changes since commit 04ffb7b107af50bd64d803b72e5fc315180381a2:
m25p80: sync flash support with the kernel (2012-11-01 12:15:26 +0800)
are available in the git repository at:

HI,
with this +1 patch serie the support of the at91sam9x5ek is mostly
complete
This will add spi and mci0 support as spi0 and mci0 conflict
We are still missing framebuffer, usb host and device and hardware i2c support
but this wil be added later
This patch serie depedsn on the at91sam9x5ek i2c and m25p80 patcheries
The following changes since commit 04ffb7b107af50bd64d803b72e5fc315180381a2:
m25p80: sync flash support with the kernel (2012-11-01 12:15:26 +0800)
are available in the git repository at:
git://git.jcrosoft.org/barebox.git delivery/at91sam9x5ek_mci_spi
for you to fetch changes up to 2c12218e89c0318dc9bed4f7f397b68903b4203e:
