mpc83xx: Fix the incorrect dcbz operation
The 834x rev1.x silicon has one CPU5 errata.
The issue is when the data cache locked with
HID0[DLOCK], the dcbz instruction looks like no-op inst.
The right behavior of the data cache is when the data cache
Locked with HID0[DLOCK], the dcbz instruction allocates
new tags in cache.
The 834x rev3.0 and later and 8360 have not this bug inside.
So, when 834x rev3.0/8360 are working with ECC, the dcbz
instruction will corrupt the stack in cache, the processor will
checkstop reset.
However, the 834x rev1.x can work with ECC with these code,
because the sillicon has this cache bug. The dcbz will not
corrupt the stack in cache.
Really, it is the fault code running on fault sillicon.
This patch fix the incorrect dcbz operation. Instead of
CPU FP writing to initialise the ECC.
CHANGELOG:
* Fix the incorrect dcbz operation instead of CPU FP
writing to initialise the ECC memory. Otherwise, it
will corrupt the stack in cache, The processor will checkstop
reset.
* For the 8349E-mITX, fix some size values in pci_init_board(), enable
the clock for the 2nd USB board (Linux kernel will hang otherwise),
and fix the CONFIG_BOOTARGS macro.

Multi-bus I2C implementation of MPC834x
Hello,
Attached is a patch implementing multiple I2C buses on the MPC834x CPU
family and the MPC8349EMDS board in particular.
This patch requires Patch 1 (Add support for multiple I2C buses).
Testing was performed on a 533MHz board.

CHANGELOG:
Implemented driver-level code to support two I2C buses on the
MPC834x CPU family and the MPC8349EMDS board. Available I2C bus speeds
are 50kHz, 100kHz and 400kHz on each bus.

Add support for multiple I2C buses
Hello,
Attached is a patch providing support for multiple I2C buses at the
command level. The second part of the patch includes an implementation
for the MPC834x CPU and MPC8349EMDS board.
Signed-off-by: Ben Warren <bwarren@qstreams.com>
Overview:
1. Include new 'i2c' command (based on USB implementation) using
CONFIG_I2C_CMD_TREE.
2. Allow multiple buses by defining CONFIG_I2C_MULTI_BUS. Note that
the commands to change bus number and speed are only available under the
new 'i2c' command mentioned in the first bullet.
3. The option CFG_I2C_NOPROBES has been expanded to work in multi-bus
systems. When CONFIG_I2C_MULTI_BUS is used, this option takes the form
of an array of bus-device pairs. Otherwise, it is an array of uchar.
CHANGELOG:
Added new 'i2c' master command for all I2C interaction. This is
conditionally compiled with CONFIG_I2C_CMD_TREE. New commands added for
setting I2C bus speed as well as changing the active bus if the board
has more than one (conditionally compiled with
CONFIG_I2C_MULTI_BUS). Updated NOPROBE logic to handle multiple buses.

NAND Flash verify across block boundaries
This patch addresses a problem when CONFIG_MTD_NAND_VERIFY_WRITE is
defined
and the write crosses a block boundary. The pointer to the verification
buffer (bufstart) is not being updated to reflect the starting of the
new
block so the verification of the second block fails.
CHANGELOG:
* Fix NAND FLASH page verification across block boundaries
- Fix issues related to the use of ELDK 4 when compiling for MarelV38B:
* remove warnings when compiling ethaddr.c
* adjust linker script (fixes a crash resulting from incorrect
definition of __u_boot_cmd_start)
- Some MarelV38B code cleanup.
- Add MPC5XXX register definition MPC5XXX_WU_GPIO_DATA_I and change the
MPC5XXX_WU_GPIO_DATA macro to MPC5XXX_WU_GPIO_DATA_O (per MPC5200 User's
Manual). Replace the uses of MPC5XXX_WU_GPIO_DATA with
MPC5XXX_WU_GPIO_DATA_O for affected boards.

Check for illegal character '=' in environment variable names.
Make sure the string passed as variable name does not contain a '='
character. This not only prevents the common error or typing
"setenv foo=bar" instead of "setenv foo bar", but (more importantly)
also closes a backdoor which allowed to delete write-protected
environment variables, for example by using "setenv ethaddr=".
Don't pass any debug options directly to the assembler
When passing the -g option to gcc, gcc automatically selects a
suitable --g<format> option to pass on to the assembler.
Thus, there's no point in forcing a specific debug option on the
assembler using the -Wa mechanism.

* gd->console_uart: A "struct device" containing information about
register mappings, gpio resources and clocks associated with the
UART device.
