I think so, but, there is some confusion in Linux machine type & other
stuff.(MACH_TYPE:180 = KS8695, MACH_TYPE:363 = KS8695P)
 
I am not a Micrel guy, but AFAIK, there is some similar KS8695 family
chips.

1. Original KS8695 : Built-in 5 MAC/PHY + 1 External MAC interface
2. KS8695X : Built-in 5 MAC/PHY + PCI bus(1 device supported)
3. KS8695P " Built-in 5 MAC/PHY + PCI bus(up to 3 devices supported)

But, all these three chips use the same core(ARM922T), and the same core
& system clock, register address spaces, so I think there is no need to
add additional chip type.

In fact, I could adapt U-Boot with few minor changes from existing
configuration. I just only changed SDRAM & FLASH registers to fit to my
board.

Do you mean the contents of include/configs/xxx.h file? or entire patch
I approved?
To submitting my patch takes some time to me for fixing up my source
code, but you may try 'make cm4008_config' or 'make cm41xx_config' for
quick testing.

BTW, I think, my original question is not related to the
misconfiguration of board, but to ARM compiler optimization.
Isn't there anyone suffer similar problem on ARM platform?
