U-Boot MPC859TnnA support !

[zjznliang]

Hi linuxppc-embedded?

                  I am porting U-Boot on the MPC859TnnA card,but U-Boot can't 
find the CPU in the initialization . I check the code ,there is not type of 
MPC859TnnA to support .The U-Boot version is 1.1.3.

                                There MPC family versions is here :

                                        MPC859DSLnnA 

                                The code in U-Boot is in the check_CPU()  (line 
48 of "\cpu\mpc8xx\Cpu.c")
                                The U-Boot supports the type of 0x08000003 but 
not 0x08010004, so add the code for 0x08010004,you will find your MPCxnnA cpu 
.:)
                                
                Perhaps I will be a help.
