The platform structure was lacking an oobinfo field.
The NDFC driver had some remains from another tree.

Some driver wants to use CMSPAR, but it was missing on alpha and powerpc.
This adds it, with the same value as every other architecture uses.

Modularize the write function and reorganaize the internal buffer
management. Remove obsolete chip options and fixup all affected
users.

Split the core of the read function out and implement
seperate handling functions for software and hardware
ECC.

Add read/write function pointers to struct nand_ecc_ctrl to
prepare the modulaization of nand_read/write functions. The
current implementation handles every type of ecc mode
software/hardware and all kinds of strange ecc placement
schemes in one switch/if construct. Thats too complex to
maintain and too inflexible to expand. Modularization will
also shorten the code pathes of the read/write functions.

FLASH - especially NAND FLASH - will become less reliable
and bit flips more likely. Add an ECC statistics struct
to struct mtd_info to keep track of this.

The nand driver has a superflous read ready / command
delay in the read functions. This was added to handle
chips which have an automatic read forward. Newer
chips do not have this functionality anymore. Add this
option to avoid the delay / I/O operation. Mark all
large page chips with the new option flag.

This patch revives pci_find_ext_capability (has been disabled a couple month
ago since it was not used anywhere. See http://lkml.org/lkml/2006/1/20/247).
It will now be used by the myri10ge driver.

The previous change of the command / hardware control allows to
remove the write_byte/word functions completely, as their only
user were nand_command and nand_command_lp.

The hwcontrol function enforced a step by step state machine
for any kind of hardware chip access. Let the hardware driver
know which control bits are set and inform it about a change
of the control lines. Let the hardware driver write out the
command and address bytes directly. This gives a peformance
advantage for address bus controlled chips and simplifies the
quirks in the hardware drivers.

MTD clients are agnostic of FLASH which needs ECC suppport.
