David Woodhouse 6411bf6cdf Revert "mtd: cleanup Kconfig dependencies"
This reverts commit 432dc821c9.

The individual CFI geometry options were carefully set up to get sane
default values if the CFI_ADV_OPTIONS wasn't set, and it wasn't
appropriate to move them into an if/endif block.

Guillaume LECERF 564b84978d mtd: cfi_cmdset_0002: do not fail on no extended query table as they are both optional
After looking at AMD's CFI specification [1], both of the extended query
tables are optional. Thus, it looks like relying that at least one of
those tables exist is a bug in cfi_cmdset_0002.

This patch inverts the logic and checks for unlock function pointers before
exiting on error. This approach leaves place to add a call to a fixup
function to try to handle chips compatible with the early AMD specification
from 1995 [2].

Stefani Seibold c4e773764c mtd: fix a huge latency problem in the MTD CFI and LPDDR flash drivers.
The use of a memcpy() during a spinlock operation will cause very long
thread context switch delays if the flash chip bandwidth is low and the
data to be copied large, because a spinlock will disable preemption.

For example: A flash with 6,5 MB/s bandwidth will cause under ubifs,
which request sometimes 128 KiB (the flash erase size), a preemption delay of
20 milliseconds. High priority threads will not be served during this
time, regardless whether this threads access the flash or not. This behavior
breaks real time.

The patch changes all the use of spin_lock operations for xxxx->mutex
into mutex operations, which is exact what the name says and means.

I have checked the code of the drivers and there is no use of atomic
pathes like interrupt or timers. The mtdoops facility will also not be used
by this drivers. So it is dave to replace the spin_lock against mutex.

There is no performance regression since the mutex is normally not
acquired.

Joakim Tjernlund 2695eab964 mtd: CFI cmdset_0002: enable erase-suspend-program
Erase-suspend for writing is required to avoid blocking applications
that wish to write some data (to a NOR block other than the one being
erased). Particularly, it solves some huge delays that an application
(which writes to a UBIFS) will experience if UBI attaches to empty NOR
flash. In this case the UBI background thread will erase a lot of blocks
and the application can be blocked for minutes because of the "MTD/CFI
chip lock".

This feature has been disabled for years. Maybe this was because the old
code turned it on for erase-suspend read-only chips also
(cfip->EraseSuspend & 0x1). This is wrong and corrected now.

Massimo Cirillo 23af51ecfb mtd: cfi_cmdset_0002: add 0xFF intolerance for M29W128G
The M29W128G Numonyx flash devices are intolerant to any 0xFF command:
in the Cfi_util.c the function cfi_qry_mode_off() (that resets the device
after the autoselect mode) must have a 0xF0 command after the 0xFF command.
This fix solves also the cause of the fixup_M29W128G_write_buffer() fix,
that can be removed now.
The following patch applies to 2.6.30 kernel.
