This patch is mainly a search and replace
s/bd->bi_memstart/bd->bi_dram[0].start. But as your test has shown, this
is not always
correct.

Again, its more a search/replace. The idea was to have no functional
change, which did not work out.

dram_init_banksize() is always called earlier, yes. But its weak default
only sets the bi_dram[] values when CONFIG_SYS_SDRAM_BASE is configured.
I'm checking right now, if this might be a problem.

Again, it started as a "simple" search and replace. It seems, that I
need to change this patch, so that the "correct" value is used in
place of bi_memstart & bi_memsize instead of always using bi_dram[].
I'll rework this patch again.

Perhaps its also the patch history that you are missing. This patch
started with a simple remove of the unreferenced CONFIG_NR_DRAM_BANKS
code paths (as the patch subject still mentions). And its extended,
after Daniel pointed out, that with the move of CONFIG_NR_DRAM_BANKS
the usage of bi_memstart etc is now not 100% correct any more. He
suggested to replace those references with bi_dram[].
I agree that this is a bit confusing. I'll rework this patch into
multiple separate patches now instead. This will hopefully make it
easier to follow the intention and review these changes.
Thanks,
Stefan
