Added a arch_preboot_os() function that cpu specific code can implement to
allow for various modifications to the state of the machine right before
we boot. This can be useful to setup register state to a specific
configuration.

Added #define CONFIG_CMD_PCMCIA around pcmcia_off() in line with other
PCMCIA drivers
signed/unsigned type fixups
Added semi-colon after default: label as required by newer gcc
The only board that appears to use this driver is the sc520_spunk which
is very old and very likely very broken anyway. I do not have one to test
whether this patch breaks anything functionaly, I have can only check
that it compiles without warning or error

Cast first parameter to sata_cpy()
In /drivers/block/ata_piix.h, ata_id_has_lba48(), ata_id_has_lba(),
ata_id_has_dma(), ata_id_u32(), ata_id_u64() are all defined in
include/libata.h which is included in ata.h which is included by all files
which include ata_piix.h (only ata_piix.c) so these definitions are
supurflous to (and conlict with) this in libata.h. Interestingly, my
compiler complains about ata_id_u64 already being defined, but not
ata_id_u32
ata_dump_id() is defined in include/libata.h and should not be static
(maybe should even use ata_dump_id() in libata.c

Atmel DataFlashes by default operate with pages that are slightly bigger
than normal binary sizes (i.e. many are 1056 byte pages rather than 1024
bytes). However, they also have a "power of 2" mode where the pages show
up with the normal binary size. The latter mode is required in order to
boot with a Blackfin processor, so many people wish to convert their
DataFlashes on their development systems to this mode. This standalone
application does just that.

Since the Blackfin ABI favors higher scratch registers by default, use the
last scratch register (P3) for global data rather than the first (P5).
This allows the compiler's register allocator to use higher number scratch
P registers, which in turn better matches the Blackfin instruction set,
which reduces the size of U-Boot by more than 1024 bytes...

Calao Systems <http://www.calao-systems.com>. Their components are very

This feature can be used to trigger special command "sysrstcmd" using
reset key long press event and environment variable "sysrstdelay" is set
(useful for reset to factory or manufacturing mode execution)
Kirkwood SoC implements a hardware-based SYSRSTn duration counter.
When SYSRSTn is asserted low, a SYSRSTn duration counter is running.
The counter value is stored in the SYSRSTn Length Counter Register
The counter is based on the 25-MHz reference clock (40ns)
It is a 29-bit counter, yielding a maximum counting duration of
2^29/25 MHz (21.4 seconds). When the counter reach its maximum value,
it remains at this value until counter reset is triggered by setting
bit 31 of KW_REG_SYSRST_CNT
Implementation:
Upon long reset assertion (> ${sysrstdelay} in secs) sysrstcmd will be
executed if pre-defined in environment variables.
This feature will be disabled if "sysrstdelay" variable is unset.
for-ex.
setenv sysrst_cmd "echo starting factory reset;
nand erase 0xa0000 0x20000;
echo finish ed sysrst command;"
will erase particular nand sector if triggered by this event

The "mac id" command took a 4-character parameter as the identifier string.
However, for any given board, only one kind of identifier is acceptable, so it
makes no sense to ask the user to type it in. Instead, if the user enters
"mac id", the identifier (and also the version, if it's NXID) will
automatically be set to the correct value.
Improve the message that is displayed when EEPROM is read during boot. It now
displays "EEPROM:" and then either an error message or the EEPROM identifier
if successful.
If the identifier in EEPROM is valid, then always reject a bad CRC, even if the
CRC field has not been initialized.
Don't force the MAC address count to MAX_NUM_PORTS or less. Forcing the value
to be changed resulting in an in-memory copy that does not match what's in
hardware, even though the user did not request that change.
Finally, always update the CRC value in the in-memory copy after any field
is changed, so that the CRC is always correct.
