1514579fbf ppc, 8xx: remove obsolete km8xx boards from keymile
The MPC852 based mgsuvd and kmsupx4 boards from keymile
were initially ported but later on not developed further. So
the respective files were removed to avoid unneeded merging
and maintenance.

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.

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) {
			...

dc71b248ef powerpc: updates for the keymile boards
- CONFIG_SYS_MAX_I2C_BUS changed to 1
  We use only one I2C hardwarecontroller on this boards, so
  change the CONFIG_SYS_MAX_I2C_BUS to 1.
- common: dont print errormsg if second IVM Block lacks.
- 82xx, mgcoge: fix double mtdpart entry in environment
- 82xx, mgcoge: activate on second Flash the second bank.
- common: CONFIG_ENV_SIZE 0x4000 for all keymile boards
- common: Change malloc size to 1MByte for all Keymile boards
    We need a bigger malloc area for the environment support (128k)
    on some Keymile boards (kmeter1) and the upcoming UBI support.
    Change it to 1MB for all Keymile boards to be on the save side.
    Also define CONFIG_SYS_64BIT_VSPRINTF which is needed for
    UBI/UBIFS support.
- Add UBI support to all Keymile boards
- change manner of writing "/localbus/ranges" node
    instead of writting the complete "/localbus/ranges" node
    before booting Linux, only update the ranges entries
    which gets dynamical detected (size of flashes).
    This is needed, because keymile adds in the DTS
    "/localbus/ranges" node entries, which u-boot must
    not overwrite/delete.
- kmeter, mgcoge: define 2 seperate regions needed for the Intel P30 chips
    The Intel P30 chip has 2 non-identical chips on
    one die, so we need to define 2 seperate regions
    that are scanned by physmap_of independantly.

a89c33db96 General help message cleanup
Many of the help messages were not really helpful; for example, many
commands that take no arguments would not print a correct synopsis

but not helpful either.

Commit ``Make "usage" messages more helpful.'' changed this
partially. But it also became clear that lots of "Usage" and "Help"
messages (fields "usage" and "help" in struct cmd_tbl_s respective)
were actually redundant.

This patch cleans this up - for example:

Before:
	=> help dtt
	dtt - Digital Thermometer and Thermostat

9b827cf172 Align end of bss by 4 bytes
Most of the bss initialization loop increments 4 bytes
at a time. And the loop end is checked for an 'equal'
condition. Make the bss end address aligned by 4, so
that the loop will end as expected.

c24853644d mgcoge, mgsuvd: add board specific I2C deblocking mechanism.
As documented in doc/I2C_Edge_Conditions, adding a
board specific deblocking mechanism via CFG_I2C_INIT_BOARD
for the mgcoge and mgsuvd board.

This code was originally written by Keymile in association
with Anatech and Atmel in 1998. The Code toggels the SCL
until the SCA line goes to HIGH (max. 16 times).
And after this, a start condition is sent.

This is another approach to deblock the I2C Bus. The
soft I2C driver actually sends 9 clocks with SDA High,
and then a stop at the end, to deblock the I2C Bus.

Maybe we should use the approach from Keymile as
the new standard?
