When using FDT Images, the length of an inital ramdisk was
overwritten (bug introduced by commit 87a449c8, 22 Aug 2006).

What was suppose to be a stack variable was declared as a pointer,
overwriting random memory.
Also moved the libfdt.a requirement into the main Makefile. That is
The U-Boot Way.
In bootm, create the "/chosen" node only if it doesn't already exist
(better matches the previous behavior).
Update for proper reserved memory map handling for initrd.
Fix bug introduced by "Fix get_partition_info() parameter error in all
other calls" from 2005-03-04 in cmd_ide.c and cmd_scsi.c, which prevented
to use diskboot or scsiboot form another device than 0.

The fdt command uses David Gibson's libfdt library to manipulate as well
as print the flattened device tree. This patch is the new command,
the second part is the modifications to the existing code.
The "old" i2c commands (iprobe, imd...) are now compiled in again,
even when the i2c command tree is enabled via the CONFIG_I2C_CMD_TREE
config option.

This patch switches to the desired I2C bus when the date/dtt
commands are called. This can be configured using the
CFG_RTC_BUS_NUM and/or CFG_DTT_BUS_NUM defines.

Block device read/write is anonymous data; there is no need to use a
typed pointer. void * is fine. Also add a hook for block_read functions

This patch is in preparation of additional changes to the sysace driver.
May as well take this opportunity to fixup the inconsistent whitespace since
this file is about to undergo major changes anyway.

In the bootvx command the load address was only read from the env
variable "loadaddr" and not optionally passed as paramter as described
in the help. This is fixed with this patch. The behaviour is now the
same as in the bootelf command.

This patch allows an arch/ppc kernel to be booted by just passing 1 or 2
arguments to bootm. It removes the getenv("disable_of") test that used
to be used for this purpose.

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.
/*** Note: This patch replaces ticket DNX#2006083042000018 ***/

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.
Updated README.
regards,
Ben

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=".
If a Multi-Image file contains a third image we try to use it as a
device tree. The device tree image is assumed to be uncompressed in the
image file. We automatically allocate space for the device tree in memory
and provide an 8k pad to allow more than a reasonable amount of growth.
Additionally, a device tree that was contained in flash will now automatically
get copied to system memory as part of boot. Previously an error was
reported if one tried to boot a device tree that was in flash.
