Nicolas Pitre 638d983840 {MTD] add support for Intel's "Sibley" flash
This updates the Primary Vendor-Specific Extended Query parsing to
version 1.4 in order to get the information about the Configurable
Programming Mode regions implemented in the Sibley flash, as well as
selecting the appropriate write command code.

This flash does not behave like traditional NOR flash when writing data.
While mtdblock should just work, further changes are needed for JFFS2 use.

Andrew Victor 8f15fd55f9 [JFFS2] Add support for JFFS2-on-Dataflash devices.
For Dataflash, can_mark_obsolete = false and the NAND write buffering
code (wbuf.c) is used.

Since the DataFlash chip will automatically erase pages when writing,
the cleanmarkers are not needed - so cleanmarker_oob = false and
cleanmarker_size = 0

DataFlash page-sizes are not a power of two (they're multiples of 528
bytes).  The SECTOR_ADDR macro (added in the previous core patch) is
replaced with a (slower) div/mod version if CONFIG_JFFS2_FS_DATAFLASH is
selected.

Nicolas Pitre 31f4233bae [MTD] User interface to Protection Registers
This is implemented using a ioctl to switch the MTD char device into
one of the different OTP "modes", at which point read/write/seek can
operate on the selected OTP area.  Also some extra ioctls to query
for size and lock protection segments or groups.  Some example user
space utilities are provided.

Nicolas Pitre f77814dd57 [MTD] Support for protection register support on Intel FLASH chips
This enables support for reading, writing and locking so called
"Protection Registers" present on some flash chips.
A subset of them are pre-programmed at the factory with a
unique set of values. The rest is user-programmable.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
