tree-wide: Assorted spelling fixes

2010-02-09T10:13:56+00:00

In particular, several occurances of funny versions of 'success',
'unknown', 'therefore', 'acknowledge', 'argument', 'achieve', 'address',
'beginning', 'desirable', 'separate' and 'necessary' are fixed.

mtd: cfi_cmdset_0002, fix lock imbalance

2009-12-10T13:33:53+00:00

Stanse found a double unlock in get_chip. get_chip is called with
chip->mutex held and caller is responsible for unlocking it too.

Do not unlock the lock in get_chip on a fail path. This would mean
a double unlock.

mtd: add support for switching old SST chips into QRY mode

2009-11-30T11:39:21+00:00

SST 39VF160x/39VF320x and some old SST chips need a special command
sequence to enter CFI QueRY mode [1].
This patch adds the relevant sequence to cfi_qry_mode_on().
Tested with 39VF3201.

mtd: fix M29W800D dev_id and uaddr

2009-11-30T11:38:32+00:00

This one sits in my tree for more than two years...
Using device code found on page 12 (http://www.btdesigner.com/pdfs/M29W800D.pdf)
and unlock address from page 15 MTD subsytem happily detects ST M29W800DB
in 16-bit mode. I do believe original author used only 8-bit mode and thus
didn't hit this bug.

mtd: CFI cmdset_0002: enable erase-suspend-program

2009-11-30T09:58:53+00:00

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.

This patch was tweaked by Norbert van Bolhuis.

mtd: move manufacturer to the common cfi.h header file

2009-11-30T09:51:26+00:00

This patch moves the MANUFACTURER_ST and MANUFACTURER_INTEL to the
include/linux/mtd/cfi.h header file and renames them to CFI_MFR_ST and
CFI_MFR_INTEL. CFI_MFR_ST was already present there.

All references in drivers/mtd/chips/cfi_cmdset_0001.c are updated to reflect
this.

mtd: add lock fixup for AT49BV640D and AT49BV640DT chips

2009-11-30T09:51:01+00:00

This patch sets the MTD_POWERUP_LOCK flag for AT49BV640D and AT49BV640DT
devices, since the devices are locked when powered up and needs to be unlocked
before interfaced.

Quote datasheet; "At power-up and reset, all sectors have their Softlock
protection mode enabled.".

Tested on AVR32 hardware platform with an AT49BV640D flash device.
