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
