Subsequent patches expect all command handlers to use a uniform
parameter naming scheme. In the entire tree, these two files used
standard 'argv' instead of our non-standard 'args'. This patch opts
to reduces the noise required to unify the command handlers, using
dominant 'args' form.
A future patch may be used to convert us back to the standard argv, but
that requires coordination with all developers to minimize disruptions.
Abstract the orion_nand_fast_block_write() routine into a separate
routine -- arm_nandwrite() -- so that other ARM cores can reuse it.
Have davinci_nand do so. This faster than byte-at-a-time ops by a
factor of three (!), even given the slowish interactions to support
hardware ECC (1-bit flavor in that test) each 512 bytes; those could
be read more efficiently by on-chip code.
NOTE that until there's a generic "ARM algorithm" structure, this
can't work on newer ARMv6 (like ARM1136) or ARMv7A (like Cortex-A8)
cores, though the downloaded code itself would work just fine there.

Almost innocuous; this is value is checked later, this
check being wrong would make it check stack garbage.

OpenOCD was able to access only to chips attached to first EMIF
chipselect. This patch fixes chipselect management code and allows
OpenOCD to access to NAND devices attached to any EMIF CS line.

Restore some whitespace that got clobbered by over-aggressive
whitepace eradication patches a while back.

Fix a bug that joined us at the last minute, when an efficient
alloca() call got swapped out for a more portable malloc().
Also log one error, to give a clue in case it appears "in the wild".

NAND support for DaVinci-family drivers, with HW ECC support.
Declare the NAND chip on the DM355 EVM board.
Currently tested on DM355 for Linux interop using the standard
large page (2KB) chip in the EVM socket; "hwecc1" and "hwecc4"
work fine. (Using hwecc4 relies on patches that haven't quite
made it through the Linux-MTD bottlenecks yet.)
Not yet tested: 1-bit on small-page (although it's hard to see
how that could fail); 4-bit on small page (picky layout issues);
the "hwecc_infix" mode (primarily for older boot ROMs; testing
there is blocked on having new bootloader code).
