Hi!

I got networking and MMC card to work on recent u-boot, but now I'm hitting DRAM region where any access just hangs the system.

Any idea what could be there / why is it hanging?

I tried reset_assert_all_bridges(), but no change.

Memory from md 100000 works ok, again, so it seems the only problematic window is 10000 to 100000.

Best regards, Pavel
