Because the code that handles bootdelay is compiled in conditionally
based on the default value, you are restricted in the default,
regardless of what you want the runtime options to be.

Change the source to always check if any default is given so that other
values can be selected and used at runtime.

The "env ask" traditionally uses a somewhat awkward syntax:

	env ask name [message ...] [size]

So far, when a mesage was given, you always also had to enter a size.
If you forgot to do that, the command would terminate without any
indication of the problem.

To avoid incompatible changes of the interface, we now check the last
argument if it can be converted into a decimal number.  If this is the
case, we assume it is a size; otherwise we treat it as part of the
message.

Also, add a space after the message fore easier reading,
and clean up help mesage.

ps on BSD hosts (like OS X) do not provide the --no-headers switch nor
understand the AIX format descriptions. Unfortunately there seems no solution to
get the PIDs of children in a platfrom independent manner.
Therefore detect the OS and decide upon that which way to go.

This patch makes the MAKEALL script cleanly stoppable on bare OS X when using
the parallel builds of targets.

Additionally this patch removes double call to grep by a single call to sed for
GNU style child PID detection.

The "mtest" command is of little practical use (if any), and
experience has shown that a large number of board configurations
define useless or even dangerous start and end addresses.  If not even
the board maintainers are able to figure out which memory range can be
reliably tested, how can we expect such from the end users?  As this
problem comes up repeatedly, we rather do not enable this command by
default, so only people who know what they are doing will be
confronted with it.

As this changes the user interface, we allow for a grace period
before this change takes effect. For now, we make "mtest"
configurable through the CONFIG_CMD_MEMTEST variable, which is defined
in include/config_cmd_default.h;  we also add an entry to
doc/feature-removal-schedule.txt which announces the removal of this
default setting in two releases from now, i. e. with v2013.07.

Currently each mpc512x board has its own LAW and CS config code,
we should avoid this code duplication. Allow all boards to use
common code by only defining LAW and CS config macros like
CONFIG_SYS_CSx_START, CONFIG_SYS_CSx_SIZE and CONFIG_SYS_CSx_CFG.

Also allow common configuration of additional CS parameters by

and CONFIG_SYS_CS_HOLDCYCLE options.

- Fix/enhance default env variables
- Fix some comments
- Add newly introduced CONFIG_SPL_TARGET to automatically build
  "u-boot-img.bin"
- Fix dtb patching in READ desciption for SPL Linux booting:
  "fdt chosen" needs to get called to patch/create the chosen node.

On MPC5200, the initial RAM (and gd) is located in the internal
SRAM. So we can actually call the preloader console init code
before calling initdram(). This makes serial output (printf)
available very early, even before SDRAM init, which has been
an U-Boot priciple from day 1.

This does not actually change normal behaviour, but adds a check that
should detect corruption of relocation data (e.g. by using BSS data
prior to relocation).

Also add additional debugging output when enabled.

During this investigation, two situations have been seen:
1. calculate_relocation_address():
	uintptr_t size = (uintptr_t)&__bss_end - (uintptr_t)&__text_start;

turns into
     111166f:	b8 83 c4 17 01       	mov    $0x117c483,%eax

whih is beyond the end of bss:

0117b484 g       .bss	00000000 __bss_end

Somehow the __bss_end here is 255 bytes ahead.

2. do_elf_reloc_fixups():

	uintptr_t size = (uintptr_t)&__bss_end - (uintptr_t)&__text_start;

Here the __text_start is 0 in the file:

 1111d9f:	bb a0 e0 13 01       	mov    $0x113e0a0,%ebx
1111da4:	81 ef 00 00 00 00    	sub    $0x0,%edi

As it happens, both of these are in pre-relocation code.

For these reasons we silent check and ignore bad relocations.
