[U-Boot] [Fwd: Re: mpc8315 DDR2 controller]

[Marcos Cunha]

Dears,

I found the problem.

The reference board (MPC8315ERDB) has 128MB DDR2. The new design has 
256MB DDR2. I chanced  the  size  macros in \incluce\configs\MPC8315E.h

#define CFG_DDR_SIZE            256 /* MB */
#define CFG_DDR_CS0_BNDS        0x0000000F  

But I forgot change MMU configurations. Below the correct configuration.

#define CFG_IBAT0U      (CFG_SDRAM_BASE | BATU_BL_256M| BATU_VS | BATU_VP)

Thanks,

Marcos Cunha
