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.

This patch correctly sets the oobavail variable
and fixes a bug where the oob data was not valid when
there where multiple groups in oobfree.
First segment fixes a typo
Second segment fixes a bug where oob data may be copied incorrectly.
Third segment adds an error message when exiting due to write protect.
Forth segment fixes a bug where oobavail may be set incorrectly.

MC13783 is a multifunction IS with an SPI interface to the host. This

This is an SPI driver for i.MX and MXC based SoCs from Freescale. So far
only implemented and tested on i.MX31, can with a modified register layout
and definitions be used for i.MX27, I think, MXC CPUs have similar SPI
controllers too.

This patch removes the board dependent parts from
"drivers/mtd/dataflash.c".
Each board relying on this, will have the appropriate
code in a new file, "partition.c" in the board directory.
board Makefiles updated to use the file.
The dataflash partitions are aligned on sector/page boundaries.
The CONFIG_NEW_DF_PARTITION was used to create named partitions
This is now the default operation, and the CONFIG variable is removed.

There are two NAND entries with ID 0xDC and this obviously causes problems.
In the kernel, they punted the first entry, so we should do the same.

It should access with 16-bit instead of 8-bit
Now it uses the generic memcpy with 8-bit access. It means it reads wrong data from OneNAND.

When the LM73 temperature sensor measures a temperature below 0 C, the
current driver does not perform sign extension, so the result returned is
512 C too high. This patch fixes the problem, and does general cleanup
of the code.

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.

This patch makes SPARC/LEON processors able to read and write
to the SMC91111 chip using the chip external I/O bus of the memory
controller. This patchs defines the standard in and out macros
expected by the SMC9111 driver.
To access that I/O bus one must set up the memory controller
(MCTRL or FTMCTRL) correctly. It is assumed that the user sets
up this correctly when the other MCTRL parameters are set up. It
can be set up from the board configuration header file.

GRETH is an Ethernet 10/100 or 10/100/1000 MAC with out without
a debug link (EDCL). The GRETH core is documented in GRIP.pdf
available at www.gaisler.com.
If the GRETH has GigaBit support (GBIT, Scatter gather, checksum
offloading etc.) can be determined by a bit in the control register.
The GBIT MAC is supported by operating in GRTEH 10/100 legacy mode.

SPARC has implemented __raw_readq, it reads 64-bit from any 32-bit address.
SPARC CPUs implement flash_read64 which calls __raw_readq.
For current SPARC architectures (LEON2 and LEON3) each read from the
FLASH must lead to a cache miss. This is because FLASH can not be set
non-cacheable since program code resides there, and alternatively disabling
cache is poor from performance view, or doing a cache flush between each
read is even poorer.
Forcing a cache miss on a SPARC is done by a special instruction "lda" -
load alternative space, the alternative space number (ASI) is processor
implementation spcific and can be found by including <asm/processor.h>.
