SH_MPC1211 has been marked as BROKEN for some time.
Unless someone is working on reviving it now, I'd therefore suggest this
patch to remove it.

Adding the ability to get a physical address from point() in addition
to virtual address. This physical address is required for XIP of

This driver did not control NCE signal during normal operations (only
enable NCE on probing and disable NCE on removing). This patch make
NCE signal inactive on idle state.

The sam926x docs allegedly don't list an "ECC_PARITY" field, and the
header files in the upstream kernel don't have it either.
Masking with it was useless anyway, so just remove it.

This is a patch to use the hardware ECC controller of
the AT91SAM9260 and AT91SAM9263 for the AT91 nand.
On AT91 NAND, there's now a choice between ECC soft,
ECC hard or no ECC (for debug).
It has been tested on AT91SAM9263 with 8 bits large
and small page NAND.

UBI scan takes quite a time on some systems, so it is nice

With modern systems using bus-hold instead of bus pull-up, it can
often lead to erroneous reporting of NAND devices where there are
none. Do a double probe to ensure that the result we got the first
time is repeatable, and if it is not then return that there is no
chip there.

If a block's ecc field is all 0xff, then ignore the ECC
correction. This is for systems where some of the blocks,
such as the initial cramfs are written without ECC and
need to be loaded on start.

A power loss while writing can result in a page becoming unreadable.
When the device is mounted again, reading that page gives controller
errors. Upper level software like JFFS2 treat -EIO as fatal, refusing to
mount at all. That means it is necessary to treat the error as an ECC
error to allow recovery. Note that typically in this case, the
eraseblock can still be erased and rewritten i.e. it has not become a
bad block.
