Hi All,
I finally got PCI support on my Xilinx ML310 with a mainline Linux
2.6.10 kernel and gcc-3.4.5-glibc-2.3.6 (with the help of the awesome
people at UNCC). Now, I'm trying to get Xilinx SystemACE device driver
support and Ethernet working. Unfortunately, I do not know much about
adding support for a driver that does not currently exist in the kernel.
Does anybody know if it would be possible to get SysACE driver support
in 2.6.10? Downloading an ELF file onto a board using a JTAG cable is
slow and inconvenient...
My attempt at adding SysACE driver support involved adding in
drivers/block/xsysace.c and linux/platform_device.h (files pulled from
mainline Linux 2.6.24) and editing drivers/block/Kconfig and
drivers/block/Makefile. The kernel failed to compile, however, and spit
out these errors:

Also, is anybody familiar with the Ethernet drivers? My boot-log
contains this error concerning Ethernet:

I also tried another Ethernet driver and got this error instead:

I know that newer versions of mainline and Xilinx Linux 2.6 have SysACE
support, but I would prefer to stick with mainline 2.6.10 because, well,
it sort of works for me at the moment (I was able to mount an ATA hard
drive with an ext2 file system). Any help/suggestions would be greatly
appreciated. Let me know if you need me to provide any additional
information. Thanks!
