This doesn't look right at all, your board is misconfigured if bd->bi_dram[i] == 0. Did you misconfigure CONFIG_NR_DRAM_BANKS ?
On some N900 devices there are two banks and on some only one. If there is only one it has size 256 MB and if there are two both has 128 MB. CONFIG_NR_DRAM_BANKS must be specified at compile time, but for N900 I need runtime detection.
How can that be? Are these two banks contiguous?
Yes.
And how does the memory map differ in case of device with one 256MB block then ?
Memory map is same, from 0x80000000 to 0x90000000.
For two bank devices uboot reports: size=08000000 start=80000000 size=08000000 start=88000000
And for one: size=10000000 start=80000000 size=00000000 start=90000000
Tom, can this not be handled as a single area? How does the omap memory layout look?
