a7efd719f4 ARM: kirkwood: reduce dependence of including platform file
For files like the drivers/serial/serial.c, it must include the
platform file, as the CONFIG_SYS_NS16550_COM1 must reference to the
definition in the platform definition files.

Include the platform definition file in the config file, so that it
would decouple the dependence for the driver files.

a2da616311 km_arm: enable POST for these boards
The current km_arm boards have a Power-On test jumper. When this
jumper is set, this triggers some Power-On tests on the board.

This patch enables the support of this jumper for starting the
memory_regions test when the jumper is set.

a55d23ccf6 Remove volatile qualifier in get_ram_size() calls
Checkpatch.pl complains about the volatile qualifier in calls to
get_ram_size(). Remove this qualifier in the prototype and in the
calls where it is useless, and leave it only in the function body
where it is needed.

01fa4e8cde arm/km: add support for portl2 board
This adds support for the keymile Kirkwood BEC portl2 board. This board
relies on the km_arm (km_kirkwood) BEC.

The egiga driver is configured for a 100M full-duplex, A/N off connnection
to the backplane. This board has always ethernet present, because it is
connected to the marvell switch similar to mgcoge3un. The reset_phy
functionality is also the same to mgcoge3un.

8612b70154 arm/km: update mgcoge3un board support
We change default settings for egiga on mgcoge3un.
The reason we need this is that we have the gig port on mgcoge3un
connected using a back-to-back pair of PHYs. There are no magnetics and
because of that the port has to be run with a fixd configuration and
auto-negotiation must be disabled. In the default mode the egiga driver
uses autoneg to determine port speed - which defaults to 1G (we need
100M full duplex).

Add wait for the GPIO line connected to mgcoge3ne before
starting mgcoge3un. A board specific ethernet present function
was added, because on this board ethernet is always present.
The BOCO FPGA access was enhanced and changed to use register
definitions.

22c67d0839 arm/km: introduce bootcount env variable and clean km_arm
This environment variable is used to set the bootcount address
for the kernel.

last_stage_init is not available for arm platforms. So the
calls to set_km_var and set_bootcount_addr are done in
misc_init_r.

Additionally some unneeded printouts were removed.

731b968044 arm, keymile: updates for the arm based boards from keymile
define KM_IVM_BUS and KM_ENV_BUS macros
 KM_IVM_BUS is used to define the EEprom_ivm environment variable.
 These macros allow the reuse of these I2C addresses in other code
 locations.

remove unneeded code
  On first HW versions the BOCO FPGA was behind a MUX device. These
  HW versions are not supported anymore. And therefore this code can
  be removed.

added LED initialization for SUEN3
  The bootstat LED required to be initialized so to have a green
  colour after start-up.

define CONFIG_SYS_TEXT_BASE
  This is needed by the relocation code and is not the same for
  our ARM BEC and thus needs to be defined.

remove memsize variable
  An environment variable for memsize is not needed.
  this can be get via the board info struct.

remove unneeded double access to bi_dram[i].size field

a9aa392629 Drop support for CONFIG_SYS_ARM_WITHOUT_RELOC
When this define was introduced, the idea was to provide a soft
migration path for ARM boards to get adapted to the new relocation
support.  However, other recent changes led to a different
implementation (ELF relocation), where this no longer works.  By now
CONFIG_SYS_ARM_WITHOUT_RELOC does not only not help any more, but it
actually hurts because it obfuscates the actual code by sprinkling it
with lots of dead and non-working debris.

So let's make a clean cut and drop CONFIG_SYS_ARM_WITHOUT_RELOC.

47e26b1bf9 cmd_usage(): simplify return code handling
Lots of code use this construct:

	cmd_usage(cmdtp);
	return 1;

Change cmd_usage() let it return 1 - then we can replace all these
ocurrances by

	return cmd_usage(cmdtp);

This fixes a few places with incorrect return code handling, too.

54841ab50c Make sure that argv[] argument pointers are not modified.
The hush shell dynamically allocates (and re-allocates) memory for the
argument strings in the "char *argv[]" argument vector passed to
commands.  Any code that modifies these pointers will cause serious
corruption of the malloc data structures and crash U-Boot, so make
sure the compiler can check that no such modifications are being done
by changing the code into "char * const argv[]".

This modification is the result of debugging a strange crash caused
after adding a new command, which used the following argument
processing code which has been working perfectly fine in all Unix
systems since version 6 - but not so in U-Boot:

int main (int argc, char **argv)
{
	while (--argc > 0 && **++argv == '-') {
/* ====> */	while (*++*argv) {
			switch (**argv) {
			case 'd':
				debug++;
				break;
			...
			default:
				usage ();
			}
		}
	}
	...
}

The line marked "====>" will corrupt the malloc data structures and
usually cause U-Boot to crash when the next command gets executed by
the shell.  With the modification, the compiler will prevent this with
an
	error: increment of read-only location '*argv'

N.B.: The code above can be trivially rewritten like this:

	while (--argc > 0 && **++argv == '-') {
		char *arg = *argv;
		while (*++arg) {
			switch (*arg) {
			...
