Several boards used different ways to specify the size of the
protected area when enabling flash write protection for the sectors
holding the environment variables: some used CONFIG_ENV_SIZE and
CONFIG_ENV_SIZE_REDUND, some used CONFIG_ENV_SECT_SIZE, and some even
a mix of both for the "normal" and the "redundant" areas.
Normally, this makes no difference at all. However, things are
different when you have to deal with boards that can come with
different types of flash chips, which may have different sector
sizes.
Here we may have to chose CONFIG_ENV_SECT_SIZE such that it fits the
biggest sector size, which may include several sectors on boards using
the smaller sector flash types. In such a case, using CONFIG_ENV_SIZE
or CONFIG_ENV_SIZE_REDUND to enable the protection may lead to the
case that only the first of these sectors get protected, while the
following ones aren't.
This is no real problem, but it can be confusing for the user -
especially on boards that use CONFIG_ENV_SECT_SIZE to protect the
"normal" areas, while using CONFIG_ENV_SIZE_REDUND for the
"redundant" area.
To avoid such inconsistencies, I changed all sucn boards that I found
to consistently use CONFIG_ENV_SECT_SIZE for protection. This should
not cause any functional changes to the code.

Now that response is a uint, we can drop all the casts.

The mmc code defines the response as an array of chars. However, it
access the response bytes both as (i) an array of four uints (with
casts) and (ii) as individual chars. The former case is used more
often, including by the driver when it assigns the response.
The char-wise accesses are broken on little endian systems because they
assume that the bytes in the uints are in big endian byte order.
This patch fixes this by changing the response to be an array of four
uints and replacing the char-wise accesses with equivalent uint-wise
accesses.

With this patch non-uniform NOR FLASH chips (chips with multiple erase
regions) can be exported via the cfi-mtd layer and therefor used by UBI.
We select the largest sector size as erasesize. The cfi driver will make
sure that the smaller sectors are handled correctly.

Fix bug in drawing long version/info strings:
U-Boot version string like
"U-Boot 2009.03-05647-g7c51e06 (Apr 23 2009 - 12:40:00) MPC83XX"
is long and doesn't wrap around correctly while drawing
beside the logo. Such long strings partially overwrite
the logo. This patch is an attempt to fix it.

With this patch the NAND and OneNAND devices are registered in the MTD
subsystem and can then be referenced by the mtdcore code (e.g.
get_mtd_device_nm()). This is needed for the new "ubi part" command
syntax without the flash type parameter (nor|nand|onenand).

Blackfin SPI driver was not driving the SPI chip-select high before
putting the chip-select signals into tri-state mode. This is probably
something that slipped by unnoticed in most designs. If the signals are
put directly into a tri-state mode, then the board is relying on the
pull-up resistors to pull up the chip-select before the next transaction.
Most of the time this is fine, except when you have two transactions that
follow each other very closely, such as the flash erase and read status
register commands. In this case I was seeing a 500ns separation between
the transactions. In my setup, with a 10kOhm pull-up, it would meet
timing spec about half the time and resulted in intermittent errors. (A
stronger pull up would fix this, but our design is targeted for low power
consumption and a 3.3kOhm @ 3.3v is 3.3mW of needless power consumption.)
I modified the spi_cs_deactivate() function in bfin_spi.c to drive the
chip-selects high before putting them into tri-state. For me, this
resulted in a rise time of 5ns instead of the previous rise time of about
1us, and fully satisfied the timing spec of the chip.

On platforms with multiple NOR chips, currently only the first one
can be selected using the "ubi part" command. This patch fixes this
problem by using different names for the NOR "mtd devices".
It also changes the name of the NOR MTD device from "cfi-mtd" to
"norX" (X indexing the device numer) to better match the mtdparts
defaults.

Mflash is fusion memory device mainly targeted consumer eletronic and
mobile phone.
Internally, it have nand flash and other hardware logics and supports
some different operation (ATA, IO, XIP) modes.
IO mode is custom mode for the host that doesn't have IDE interface.
(Many mobile targeted SoC doesn't have IDE bus)
This driver support mflash IO mode.
Followings are brief descriptions about IO mode.
1. IO mode based on ATA protocol and uses some custom command. (read
confirm, write confirm)
2. IO mode uses SRAM bus interface.

Legacy NAND is marked for feature removal after April 2009 (i.e. this
upcoming release). There are still several boards that reference it
(though many do so only for disk-on-chip support which has been silently
disabled for a while now). These boards will now fail to build
with #error, though the code is still there if the user removes #error.
The plan is to remove the code outright in the next release, along with
any board code that refers to it (such as board/esd/common/auto_update.c).
Also, remove the legacy NAND API description from README.nand.

I can't find anywhere in the datasheet that says the status register needs
3 dummy bytes sent to it before being able to read back the first real
result. Tests on a Blackfin board show that after writing the opcode, the
status register starts coming back immediately. So only write out the
read status register opcode before polling the result.

Since timeouts are only hit when there is a problem in the system, we
don't want to prematurely timeout on a functioning setup. Thus having
low timeouts (in milliseconds) doesn't gain us anything in the production
case, but rather increases likely hood of causing problems where none
otherwise exist.
