mtd: fix hang-up in cfi erase and read contention 2011-05-25T01:11:11+00:00 Tadashi Abe tabe@mvista.com 2011-05-19T06:58:15+00:00 100f2341e305f98de3aa12fb472771ab029cbda7 cfi erase command hangs up when erase and read contention occurs. If read runs at the same address as erase operation, read issues Erase-Suspend via get_chip() and the erase goes into sleep in wait queue. But in this case, read operation exits by time-out without waking it up. I think the other variants (0001, 0020 and lpddr) have the same problem too. Tested and verified the patch only on CFI-0002 flash, though.
