2472216cac arm/km: fix memory settings
On kmcoge5un we faced some serious problems with the memory during
temperature tests. Reason was that we overwrite some registers for
memory settings which have to leave untouched. These where registers
0x20148 , 0x2014c and 0x20154.
So writing these registers is prohibited and this patch removes them
from all km related config files. Even if the problem was only
seen on kmcoge5un.

52638c4147 arm/km: add mv88e6352 configuration for kmnusa
The kmnusa board uses a mv88e6352 switch that is connected to the main
eth interface of the kirkwood. Therefore the switch must be configured
so that the kirkwood's egiga eth inferface can be used.

c471d84808 arm/km: remove calls to kw_gpio_* in board_early_init_f
These functions tried to access two static tables before relocation
(board_early_init_f is executed before relocation). But these static
tables lie in the bss section which is not valid before relocation.
These accesses then overwrote some parts of u-boot binary before it was
relocated. For the kmnusa build, this results in a corrupted important
env variable (bootcmd) but it may be that some other parts of the u-boot
binary are corrupted.

This patch solves this problem by moving all the kw_gpio_* calls to
board_init, which should be early enough in the boot sequence. The only
calls that could not be moved is the one for the SOFT (bitbang) I2C, and
they have been replaced by a direct access to the GPIO dataout Control
register to set the two GPIOs as output.

bcac5b1b2c arm/km: skip FPGA config when already configured
In order to be able to perform board resets without interrupting the
traffic, the configuration of an already properly configured FPGA is
skipped.

This is because some PCIe FPGAs embed some other function that must
continue to work over reset.

It is then the responsibility of the application to trigger a
reconfiguration when needed. This is done by lowering the FPGA_INIT_B
pin for delaying the configuration to u-boot @ next reboot, and then
lower the FPGA_PROGRAM_B signal.

b37f772433 arm/km: enable BOCO2 FPGA download support
This adds a first support of the FPGA download for a PCIe FPGA based
on the BOCO2 CPLD.

This takes place in 3 steps, all done accessing the SPICTRL reg of the
BOCO2:
1) start the FPGA config with an access to the FPGA_PROG bit
2) later in the boot sequence, wait for the FPGA_DONE bit to toggle to 1
   for the end of the FPGA configuration (with a timeout)
3) reset the FPGA
4) finally remove the access to its config EEPROM from the FPGA so that
   the CPU can update the FPGA configuration when the kernel is running

The boards with a PCIe FPGA but without BOCO2 still are supported.

The config option name is CONFIG_KM_FPGA_CONFIG

The bootcounter (stored in the RAM) is not enough protected with the 4 Bytes
BOOTCOUNT_MAGIC against bit errors due to short power loss or holding a system

A bit pattern with 4000 bytes (after BOOTCOUNT_MAGIC) has been implemented,
which should be enough to detect a bit error.

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.

44097e26cc km-arm: i2c support for suenx based boards
This patch renames the suen3 defines and functions to KM_KIRKWOOD
which is more generic and more precise, because these values
and functions where used by all suenX boards and not only suen3.

b11f53f31b keymile: Fix Coding style issues for keymile boards.
- use I/O accessors
  -> For accessing the FPGA therefore a struct km_bec_fpga
     is introduced.
- no longer externs needed
- to defines, that only select functions, don;t assign a
  numeric value
- Codingstyle changes to prevent checkpatch errors/warnings

802d996324 arm, keymile: rename MACH_SUEN3 to MACH_KM_KIRKWOOD
The MACH_TYPE SUEN3 is now to specific for keymile boards, because
other boards similar to suen3 will follow. So the MACH_SUEN3 was renamed
to MACH_KM_KIRKWOOD.

086f09150d arm, keymile: 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, it is already unused.

6d8962e814 Switch from archive libraries to partial linking
Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

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.

31d80c77ff kirkwood: get rid of config.mk files
After moving the definition of CONFIG_SYS_TEXT_BASE to the respective
board config files, all Marvell kirkwood board have just a single and
common entry in their config.mk files:

	KWD_CONFIG = $(SRCTREE)/board/$(BOARDDIR)/kwbimage.cfg

Replace the only reference to KWD_CONFIG in the top level Makefile by
an equivalent setting, and remove all kirkwood config.mk files.

14d0a02a16 Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE
The change is currently needed to be able to remove the board
configuration scripting from the top level Makefile and replace it by
a simple, table driven script.

Moving this configuration setting into the "CONFIG_*" name space is
also desirable because it is needed if we ever should move forward to
a Kconfig driven configuration system.

Change the implementation for arm926 to relocate the code to
an arbitrary address in RAM.

Adapt the TX25 (i.MX25), magnesium board to test the changes.

On the tx25 board TEXT_BASE is set to the final relocation
address to prevent one more copying of u-boot code
when relocating. More info see:

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) {
			...
