Hi Claudia,
There may be other changes besides this, but you need to modify
the sdramc_init() routine in:
arch/m68k/platform/532x/config.c
void sdramc_init(void)
{
...
/* Initialize SDRAM chip select */
MCF_SDRAMC_SDCS0 = (0
| MCF_SDRAMC_SDCS_BA(SDRAM_ADDRESS)
| MCF_SDRAMC_SDCS_CSSZ(MCF_SDRAMC_SDCS_CSSZ_32MBYTE));
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
s/b MCF_SDRAMC_SDCS_CSSZ_64MBYTE
Regards,
Matt
