Since we're working with unsigned data, you can't apply a signed pointer
cast and then attempt to print the result. Otherwise you get wrong output
when the sign bit is set like "0xFF" incorrectly extended to "0xFFFFFFFF".

We don't need CONFIG_CFG_STRINGS anymore now that we have the define
CONFIG_CMD_STRINGS and Makefile control.

Commit 2a1a2cb6 didnt remove the dummy mem reservation in fdt_chosen,
and this stopped Linux from booting with a Ramdisk. This patch fixes
this, by deleting the useless dummy mem reservation.
When booting with a Ramdisk, a fix offset FDT_RAMDISK_OVERHEAD is now
added to of_size, so we dont need anymore a dummy mem reservation.
I measured the value of FDT_RAMDISK_OVERHEAD on a MPC8270 based
system (=0x44 bytes) and rounded it up to 0x80).

When not using hush, the autoscr command now executes lines that are
only one character long. It also runs the last line of scripts even if
it does not end in a newline.

Fix printf format-string/arg mismatches under -DDEBUG.
These warnings occur with DEBUG defined for a platform using
cpu/mpc85xx. Users of other architectures can unearth similar
problems by adding the line "CFLAGS += -DDEBUG=1" in config.mk right
after "CFLAGS += $(call cc-option,-fno-stack-protector)".

The patch is that check if usb_get_dev_index() function return valid

A recent commit (936897d4d1)
enabled the usb_stop() command in common/cmd_bootm.c which was
not enabled for some time, because no board did actually set the
CFG_CMD_USB flag. So, now the usb_stop() is executed before
loading the linux kernel.
However, the usb_ohci driver hangs up (at least on AT91SAM) if the
driver is stopped twice (e.g. the peripheral clock is stopped on AT91).
If some other piece of code calls usb_stop() before the bootm command,
this command will hangup the system during boot.
(usb start and stop is typically used while booting from usb memory stick)
But, stopping the usb stack twice is useless anyway, and a flag already
existed that kept track on the usb_init()/usb_stop() calls.
So, we now check if the usb stack is really started before we stop it.
This problem is now fixed in both the upper as low-level layer.

Pantelis Antoniou stated:
AFAIK, it is still used but the products using PPC are long gone.
Nuke it plz (from orbit).
So remove it since it cleans up a usage of env_get_char outside of
the environment code.

Several source files need to be compiled and linked when one or more
config options are selected. To allow for easy selection in the
Makefiles yet to avoild multiple compilation (which costs build time)
and especially multiple linking (which causes errors), we use
"COBJS = $(sort COBJS-y)" which eliminates duplicates.
By courtesy of Detlev Zundel who suggested this approach.

Adds returning an error from the ramdisk detection code if
its not a real ramdisk (invalid). There is no reason we can't
just return back to the console if we detect an invalid
ramdisk or CRC error.

This patch adds bootm_start() return value check. If
error status is returned, we do not proceed further to
prevent board reset or crash as we still can recover
at this point.
