fb8d81e477 [PATCH] MTD NAND: Fix ams-delta after core conversion
The recent hwctrl core conversion for MTD NAND devices broke the Amstrad
Delta driver.  This fixes it up and uses the existing control line defines
rather than unclear magic numbers.

cad74f2c38 [MTD] NAND remove write_byte/word function from nand_chip
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.

7abd3ef987 [MTD] Refactor NAND hwcontrol to cmd_ctrl
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.

6dfc6d250d [MTD] NAND modularize ECC
First step of modularizing ECC support.
- Move ECC related functionality into a seperate embedded data structure
- Get rid of the hardware dependend constants to simplify new ECC models

3d12c0c75d [MTD] Add Amstrad Delta NAND support
The patch below adds support for the NAND device on the Amstrad Delta.
This is a 32MiB 8bit Toshiba device, with the data bus connected to the
OMAP MPUIO pins and ALE, CLE, NCE, NRE, NWE and NWP all connected to the
Delta's latch2 16bit latch.
