CFI: allow for dynamically determined flash sizes and addresses

The CFI driver allowed only for static initializers in the
CFG_FLASH_BANKS_LIST definition, i. e. it did not allow to map
several flash banks contiguously if the bank sizes were not known in
advance, which kind of violates U-Boot's design philosophy.

(will be used for example by the TQM8xxL boards)

cfi_flash: fix flash on BE machines with CFG_WRITE_SWAPPED_DATA

This got broken by commits 93c56f212c
[cfi_flash: support of long cmd in U-boot.]

That command needs to be in little endian format on BE machines
with CFG_WRITE_SWAPPED_DATA. Without this patch, the command 0xf0
gets saved on stack as 0x00 00 00 f0 and 0x00 gets written into
the cmdbuf in case portwidth = chipwidth = 8bit.

This got changed by commit 93c56f212c

Long is the wrong type because it will behave differently on 64bit
machines in a way that is probably not expected. u32 should be
enough.

cfi-flash: Fix problem in flash_toggle(), busy was not detected reliably

This patch simplifies flash_toggle() (AMD commandset), which is used to
detect if a FLASH device is still busy with erase/program operations. On
800MHz Canyonlands/Glacier boards (460EX/GT) the current implementation
did not detect the busy state reliably, resulting in non erased sectors
etc. This patch now simplifies this function by "just" comparing the
complete data-word instead of ANDing it with the command-word (0x40)
before the compatison. It is done the same way in the Linux implementation
chip_ready() in cfi_cmdset_0002.c.

cfi-flash: Add CFG_FLASH_AUTOPROTECT_LIST

This patch adds a configurable flash auto protection list that can be used
to make U-Boot protect flash regions in flash_init().

The idea has been discussed on the u-boot mailing list starting
on Nov 18th, 2007.

Even this patch brings a new feature it is used as a bugfix for 4xx
platforms where flash_init() does not completely protect the
monitor's flash range in all situations.

U-Boot protects the flash range from CFG_MONITOR_BASE to
(CFG_MONITOR_BASE + monitor_flash_len - 1) by default. This does not
include the reset vector at 0xfffffffc.

Example:
#define CFG_FLASH_AUTOPROTECT_LIST {{0xfff80000, 0x80000}}

This config option will auto protect the last 512k of flash that
contains the bootloader on board like APC405 and PMC405.

cfi_flash: Support buffered writes on non-standard Spansion NOR flash

Some NOR flash chip from Spansion, for example, the s29ws-n MirrorBit
series require different addresses for buffered write commands. Define a
configuration option to support buffered writes on those chips. A more
elegant solution would be to automatically detect those chips by parsing
their CFI records, but that would require introduction of a fixup table
into the cfi_flash driver.
