This is very simple driver, NAND is connected through localbus,
and User-Programmable Machine is doing various adjustments to
speak NAND. No special efforts needed to do read and write cycles,
though to control ALE and CLE phases, we ask UPM to generate exact
pre-programmed signals on the localbus lines.

This enhances plat-ram to take a map_probes argument in
the platform_data structure which allow plat-ram to support
any direct-mapped device that MTD supports (jedec, cfi, amd ..)

A few items are also fixed:
- Don't panic if probes is 0
- Actually use the partition list that is passed in

This is preliminary since:

1. It supports only _one_ chip select at the moment. As there is no
   existing platforms available using two chip selects of the NAND
   controller, it shall really not include code for supporting the
   2nd chip select for now, as such code cannot be verified.

2. It resorts to the default and simpliest memory based badblock
   table

3. Only limited types of nand flash are currently supported. Most
   PXA3xx processors come with on-chip NAND flash dies, so there
   isn't much flexibility for other types of NAND.

4. The NAND controller should be configured to detect the device's
   ID, thus making it difficult to use nand_scan_ident() to assist
   the detection process (though it's not impossible)

TODO: fix all the above limitations of cuz :-)

Since 43cc71ee, the platform modalias is
prefixed with "platform:".  Add MODULE_ALIAS() to the hotpluggable MTD NAND
platform drivers, to re-enable auto loading.

NOTE: at91_nand for some reason disallows modular builds.  I'm assuming that's
just an oversight that will be fixed.

NOTE oddness with physmap ...  it's a legacy driver in some configs, which
means it can't always support hotplugging.  (Not that most of these mapping
drivers would often be used as modules...)

I found this while I was looking how the rs_lib is working.  The rs_decoder is
initialized _after_ the nand core code read the BBT table and _after_ the
partition table has been added.  The driver has a private BBT description
which is in located in flash data so we Ooops if there is a bit flip _or_ if a
bit flips while reading the partition table.

This patch moves the initialization of the rs_lib before the first possible
access by nand core.
