The patch improves flash erase for STR9x in case of a full bank erase.
Then the chip erase command is used instead which improves speed significantly.
Also I think it might help if e.g. STR912 enters some state where flash banks are locked, and a chip erase command is the key for unlocking the flash.
Final target is to force bus_width size during CFI flash
read.
In this first step I need to replace default flash read
with flash specific implementation.
This patch introduces:
- flash_driver_read() layer;
- default_flash_read(), backward compatible;
- read() callback in struct flash_driver;
- proper initialization in every flash_driver instance.

Using the erase bank command will cause a time out error. Replacing
this with the erase sector bank will provide a slower but safer and
stable method to erase the flash.

Make "usage" messages use the same EBNF as the User's Guide;
no angle brackets. Improve and correct various helptexts.
Don't use "&function"; a function's name is its address.
Remove a couple instances of pointless whitespace; shrink a
few overlong lines; fix some bad indents.
Add TODO list entry re full support for NAND/NOR bank names.

Changes from the flat namespace to heirarchical one. Instead of writing:
#include "arm966e.h"
the following form should be used.
#include <target/arm966e.h>
The exception is from .c files in the same directory.
