In cpu dir, there is arm920t/ks8695. ks8695p is some modified chip from ks8695.
do this modification is U-Boot mainline supported?
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.
In board section, OpenGear cm4008 and cm41xx uses ks8695.
could give the board configuration? make xxxx_config
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?
