Hi All

For people who is interested in pxa simulation using skyeye to run
linux. Here is patch for latest linux kernel:  linux-2.6.23.9
(including config file).

After applied patch, you can run:
make lubbockskyeye_defconfig
make
skyeye -e vmlinux
and you can adjust your configuration by make menuconfig or xconfig later.

The problem of kernel 2.6.23 is that it introduced cpu_is_pxaXXX
macros. And modified pxa_init() function to check cpu id, and then
call platform_add_devices() and also try to init dma and
hardware-uart, which  skyeye seems don't support.

The skyeye_ts.c(h) are included as well. But they are not used by
simulation at moment, just of your reference.

Y.W
