Make DMA transactions snoopable so that CPUs can keep caches up-to-date.
This allows dma transactions to be used for operations such as memory
copies without any additional cache control operations.

The Channel Start (CS) bit in the Mode Register (MR) should actually be
cleared as the comment in the code suggests. Previously, CS was being
set, not cleared.
Assuming normal operation of the DMA engine, this change shouldn't have
any real affect.

This reverts commit ca9c8a1e10fac01e6a1129f82a7ce18bd818fa43,
which causes compile warnings ("large integer implicitly truncated
to unsigned type") on all systems that use this driver. The warning
results from passing long constants (TX_CFG, RX_CFG) into
smc911x_set_mac_csr() which is declared to accept "unsigned
character" arguments only.
Being close to a release, with nobody available to actually test the
code or the suggested fixes, it seems better to revert the patch.

The uec driver contains code to hard code configuration information for the uec
ethernet controllers. This patch creates an array of uec_info structures, which
are then parsed by the corresponding driver instance to determine configuration.
It also creates function uec_standard_init() to initialize all UEC interfaces
for 83xx and 85xx.

This patch adds NAND Flash Controller driver for MPC5121 revision 2.
All device features, except hardware ECC and power management, are
supported.
This NFC driver replaces the one orignally posted by John Rigby:
"[PATCH] Freescale NFC NAND driver"
It's a port of the Linux driver version posted by Piotr Ziecik a few
weeks ago. Using this driver has the following advantages (from my
point of view):
- Compatibility with the Linux NAND driver (e.g. ECC usage)
- Better code quality in general
- Resulting U-Boot image is a bit smaller (approx. 3k)
- Better to sync with newer Linux driver versions
The only disadvantage I can see, is that HW-ECC is not supported right
now. But this could be added later (e.g. port from Linux driver after
it's supported there). Using HW-ECC on the MCP5121 NFC has a general
problem because of the ECC usage in the spare area. This collides with
JFFS2 for example.

as under:-
* Moves the 83xx USB clock init from drivers/usb/host/ehci-fsl.c to
cpu/mpx83xx/cpu_init.c
* Board specific usb_phy_type is read from the environment
* Adds USB EHCI specific structure in include/usb/ehci-fsl.h
* Copyrights revamped in most of the following files

Move needed definitions (register descriptions etc.) from
include/mpc512x.h into include/asm-ppc/immap_512x.h.
Instead of using a #define'd register offset, use a function that
provides the PATA controller's base address.
All the rest of include/mpc512x.h are register offset definitions
which can be eliminated by proper use of C structures.
There are only a few register offsets remaining that are needed in
cpu/mpc512x/start.S; for these we provide cpu/mpc512x/asm-offsets.h
which is intended as a temporary workaround only. In a later patch
this file will be removed, too, and then auto-generated from the
respective C structs.

Many of the help messages were not really helpful; for example, many
commands that take no arguments would not print a correct synopsis
line, but "No additional help available." which is not exactly wrong,
but not helpful either.
Commit ``Make "usage" messages more helpful.'' changed this
partially. But it also became clear that lots of "Usage" and "Help"
messages (fields "usage" and "help" in struct cmd_tbl_s respective)
were actually redundant.
This patch cleans this up - for example:
Before:
=> help dtt
dtt - Digital Thermometer and Thermostat
Usage:
dtt - Read temperature from digital thermometer and thermostat.
After:
=> help dtt
dtt - Read temperature from Digital Thermometer and Thermostat
Usage:
dtt

This new define enables mtdcore.c compilation and with this we can
select the MTD device infrastructure needed for the reworked mtdparts
command.
We now have the 2 MTD infrastructure defines, CONFIG_MTD_DEVICE and
CONFIG_MTD_PARTITIONS. CONFIG_MTD_DEVICE is needed (as explained above)
for the "mtdparts" command and CONFIG_MTD_PARTITIONS is needed for UBI.

This patch brings the U-Boot MTD infrastructure in sync with the current

meanwhile.

This patch adds concatenation support to the U-Boot MTD infrastructure.
By enabling CONFIG_MTD_CONCAT this MTD CFI wrapper will concatenate
all found NOR devices into one single MTD device. This can be used by
e.g by UBI to access a partition that spans over multiple NOR chips.

Zoom2 serial is in general supplied by one of the 4 UARTS on the debug board.
The default serial is from the USB connector on left side of the debug board.
The USB connector will produce 2 of the 4 UARTS. On your host pick the first
enumeration.
The details of the setting of the serial gpmc setup are not available.
The values were provided by another party.
The serial port set up is the same with Zoom1.
Baud rate 115200, 8 bit data, no parity, 1 stop bit, no flow.

New default, weak i2c_get_bus_speed() and i2c_set_bus_speed() functions
replace a number of architecture-specific implementations.
Also, providing default functions will allow all boards to enable
CONFIG_I2C_CMD_TREE. This was previously not possible since the
tree-form of the i2c command provides the ability to display and modify
the i2c bus speed which requires i2c_[set|get]_bus_speed() to be
present.
