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).

As the common code also handles baudrate switching, which the board
specific vct.c driver did not support, this is one of the rare
occassions where deleting code actually adds a feature :)

__attribute__ follows gcc's documented syntax and is generally more

Make the U-Boot dm9000 driver read addresses from EEPROM just
like Linux does ... read six bytes, instead of reading twelve
bytes and then discarding every other one.
Using the right Ethernet address is a big win.

We need to make sure the data written to the nand flash controller makes
it there before we start polling its status register. Otherwise, we may
get stale data and return before the controller is actually ready.

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.

Fix problems introduced in commit
7b5611cdd12ca0cc33f994f0d4a4454788fc3124 [inka4x0: Add hardware
diagnosis functions for inka4x0] which redefined MSR_RI which is
already used on PowerPC systems.
Also eliminate redundant definitions in ps2mult.h. More cleanup will
be needed for other redundant occurrences though.

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.

Some SPI flash drivers like to have extended id information available
(like the spansion flash), so rather than making it re-issue the ID cmd
to get at the last 2 bytes, have the common code read 5 bytes rather than
just 3. This also matches the Linux behavior where it always reads 5 id
bytes from all flashes.
