I'm trying to get things up and running on a Xilinx Virtex-4 ml405
board,
and as such I've been trying to figure out the following recent message
to
the list:
http://patchwork.ozlabs.org/linuxppc/patch?person=1226&id=17037
I don't understand what this patch applies to: it references files such
as
ml405_defconfig which are not part of the normal kernel tree and which I
cannot find anywhere. Is there some other kind of patch that needs to
apply
first in order to get for instance CONFIG_XILINX_DRIVERS,
CONFIG_XILINX_EMAC, etc...
It applies to Xilinx's git tree of the Linux kernel.
Fair enough.
OK, I managed to install git, download the Xilinx kernel source tree,
integrate it into root and compile it successfully...
Now I'd like to understand this ml405_defconfig file. I cannot replace my
.config with it because it gives me:
$ make ARCH=ppc linux26-menuconfig

So my question is that even with a full (?) Xilinx kernel, there seems to be
missing drivers. Does this have to do with the BSP ?
Thanks
