Being a value which isn't in the table is a case we explicitly check for
in the caller. Don't BUG_ON() because it does actually happen in
practice.

Ditch the separate oobrbuf and oobwbuf fields from the chip buffers,
and use only a single buffer immediately after the data. This accommodates
NAND controllers such as the OLPC CAFÉ chip, which can't do scatter/gather
DMA so needs the OOB buffer to be contiguous with the data, for both read
and write.

As flash cannot do 0->1 bit transitions when programming, do not do this in
the simulator too. This makes nandsim able to accept subpage writes.

During some testing with several samsung s3c24xx based
devices it was discovered that often the
cfi_cmdset_0001.c would not leave the chip in
read-array mode on suspend. this is an issue if the
same flash chip is used for the bootloader that needs
to be read on resume.

For page wise allocation, an array of flash page pointers is allocated
during initialization. The flash pages are themselves allocated when a
write occurs to the page. The flash pages are deallocated when they
are erased.

1. The ECCGETLAYOUT ioctl copy_to_user() call has a superfluous '&'
causing the resulting information to be garbage rather than the intended
mtd->ecclayout.

2. The MEMGETOOBSEL misses copying mtd->ecclayout->eccbytes so the
resulting field of the returned structure contains garbage.

This version only differs from version posted by Savin Zlobec (20 Jun
2006) in that the AT91RM9200-specific chip-select / bus setup code has
been moved from the at91_nand.c driver into the processor-specific file.

The 2 bits controlling the window size are often set to allow reading the
BIOS, but too small to allow writing, since the lock registers are 4MiB
lower in the address space than the data.  This is intended to prevent
flashing the bios, perhaps accidentally.

The bits are 6 and 7.  If both bits are set, it is a 5MiB window. If only
the 7 Bit is set, it is a 4MiB window.  Otherwise, it is a 64KiB window.

This parameter allows the driver to override the BIOS settings.

This reverts commit 4596c75c as
requested by Olaf Hering. It causes compile errors, and says Olaf:

  "This change is also wrong, the autoloading works perfect with 2.6.18,
   no need to add random PCI ids.

   See commit a0245f7a, platform devices
   have now a modalias entry in sysfs.  The network card is not a PCI
   device."
