Re: [PATCH] ppc32: ppc_sys fixes for 8xx and 82xx

Hi Vitaly,

This patch fixes a numbers of issues regarding to that both 8xx and 82xx 
began to use ppc_sys model:
	- Platform is now identified by default deviceless SOC, if no 
BOARD_CHIP_NAME is specified in the bard-specific header. For the list 
of supported names refer to (arch/ppc/syslib/) mpc8xx_sys.c and 
mpc82xx_sys.c for 8xx and 82xx respectively.
	- Fixed a bug in identification by name - if the name was not found, 
	it returned -1 instead of default deviceless ppc_spec.
	- fixed devices amount in the 8xx platform system descriptions

Patch looks good. 

For 8xx, I was wondering if the PARTNUM field of the IMMR 
(section 10.4.1 of MPC860UM.pdf) does have meaningful 
information which could be used to identify the CPU.
