cache invalidation error for buffered write

2008-01-11T19:44:37+00:00

The bug causes corruptions of data read from flash.

The original code performs cache invalidation from "adr" to "adr + len"
in do_write_buffer().  Since len and adr could be updated in the code
before invalidation - it causes improper setting of cache invalidation
regions.

[MTD] [NOR] Fix deadlock in Intel chip driver caused by get_chip recursion

2007-10-23T11:07:52+00:00

This patch solves kernel deadlock issue seen on JFFF2 simultaneous 
operations. Detailed investigation of the issue showed that the kernel 
deadlock is caused by tons of recursive get_chip calls.

[MTD] [NOR] fix ctrl-alt-del can't reboot for intel flash bug

2007-10-13T13:36:18+00:00

When we press ctrl-alt-del,kernel_restart_prepare will invoke 
cfi_intelext_reboot which will set flash to read array mode, but later 
when device_shutdown is invoked which may put current work queue to 
sleep and other process may be scheduled to running and programming 
flash in not FL_READY mode again. So we can't boot up if this flash is 
used for bootloader.

[MTD] fix CFI point method for discontiguous maps

2007-09-23T17:40:49+00:00

The CFI probe routine is capable of detecting flash banks consisting of
identical chips mapped to physically discontiguous addresses.  (One
common way this can occur is if a flash bank is populated with chips of
less capacity than the hardware was designed to support.)  The CFI
point() routine currently ignores any such gaps.  This patch fixes
the CFI point() routine so that it truncates any request that would
span a gap.
