[U-Boot] Bad CPU identification on MPC8544DS

[jeff angielski]

Despite the SVR being the same (0x803c0011), the latest u-boot is
misidentifying the CPU when compared against the original 1.3.0 u-boot.
The CPU is a 8544E but u-boot is reporting 8533E.

The wierd part of this is that according to the Chip Errata for the
MPC8544E, the SVR *should* be 0x803c01xx  - which is different than both
the 1.3 and latest git version are reading.

Can any of the Freescale guys explain this discrepancy between the
manual, the Freescale BSP u-boot, and the latest u-boot?



Using the u-boot that is built with the LTIB and ships with the
MPC8544DS board:



U-Boot 1.3.0-rc3 (Mar 28 2008 - 11:13:50)

CPU:   8544_E, Version: 1.1, (0x803c0011)
Core:  E500, Version: 2.2, (0x80210022)  
Clock Configuration:                     
       CPU: 999 MHz, CCB: 399 MHz,       
       DDR: 199 MHz, LBC:  24 MHz        
L1:    D-cache 32 kB enabled             
       I-cache 32 kB enabled             



Using the latest u-boot:


U-Boot 2009.03-rc1-00031-gd82fd0f-dirty (Mar 03 2009 - 13:09:00)

CPU:   8533E, Version: 1.1, (0x803c0011)
Core:  E500, Version: 2.2, (0x80210022) 
Clock Configuration:                    
       CPU0:1000 MHz,                   
       CCB:400  MHz,                    
       DDR:200  MHz (400 MT/s data rate), LBC:25   MHz
L1:    D-cache 32 kB enabled                          
       I-cache 32 kB enabled                          
Board: MPC8544DS, System ID: 0x12, System Version: 0x20, FPGA Version:
0x31
