Hello, as I am actual trying to get the keymile boards in sync with actual mainline u-boot, I faced the following Problem with an Intel Strata Flash on the mgcoge (mpc8247 based board):
I couldn;t unprotect/erase/write/protect some (not all!) Flash sectors. For Example, I could do this without errors on the sectors where u-boot sits (First three sectors), but not with the environment (next two sectors)! After some debugging, I found out, that, if I revert commit commit 54652991caedc39b2ec2e5b49e750669bfcd1e2e Author: Philippe De Muyter <p...@macqel.be> Date: Tue Aug 17 18:40:25 2010 +0200 Work around bug in Numonyx P33/P30 256-Mbit 65nm flash chips. I have "ported" U-boot to a in house made board with Numonyx Axcell P33/P30 256-Mbit 65nm flash chips. After some time :( searching for bugs in our board or soft, we have discovered that those chips have a small but annoying bug, documented in "Numonyx Axcell P33/P30 256-Mbit Specification Update" [...] It works again fine, and without problems ... did somebody faced similiar issues with the cfi driver?
