afc3ba0fc4 relocation: Do not relocate NULL pointers.
NULL is an absolute value and should not be relocated.
After this correction code like:
 void weak_fun(void) __attribute__((weak));
 printf("weak_fun:%p\n", weak_fun);
will still print null after relocation.

da01f53404 mpc512x: fix fixed_sdram() init code.
Commit 054197ba and later fixes used an array to initialize some of
the MDDRC parameters; however, the use of an array turned out to be a
bad idea as it was not possible to correlate structure entries to
array indices in readable and reliable way. Now we use a struct
instead, which makes this self-explanatory.

858290178f ppc: Enable full relocation to RAM
The following changes allow U-Boot to fully relocate from flash to
RAM:
 - Remove linker scripts' .fixup sections from the .text section
 - Add -mrelocatable to PLATFORM_RELFLAGS for all boards
 - Define CONFIG_RELOC_FIXUP_WORKS for all boards

Previously, U-Boot would partially relocate, but statically initialized
pointers needed to be manually relocated.

054197ba8e mpc512x: Streamlined fixed_sdram() init sequence.
Signed-off-by: Martha M Stan <mmarx@silicontkx.com>

Minor cleanup:

Re-ordered default_mddrc_config[] to have matching indices.

This allows to use the same index "N" for source and target fields;
before, we had code like this

	out_be32(&im->mddrc.ddr_time_config2, mddrc_config[3]);

which always looked like a copy & paste error because 2 != 3.

Also, use NULL when meaning a null pointer.

52cb4d4fb3 stdio/device: rework function naming convention
So far the console API uses the following naming convention:

	======Extract======
	typedef struct device_t;

	int	device_register (device_t * dev);
	int	devices_init (void);
	int	device_deregister(char *devname);
	struct list_head* device_get_list(void);
	device_t* device_get_by_name(char* name);
	device_t* device_clone(device_t *dev);
	=======

which is too generic and confusing.

Instead of using device_XX and device_t we change this
into stdio_XX and stdio_dev

This will also allow to add later a generic device mechanism in order
to have support for multiple devices and driver instances.

7629f1c06b MPC512x: factor out common code
Now that we have 3 boards for the MPC512x it turns out that they all
use the very same fixed_sdram() code.

This patch factors out this common code into cpu/mpc512x/fixed_sdram.c
and adds a new header file, include/asm-ppc/mpc512x.h, with some
macros, inline functions and prototype definitions specific to MPC512x
systems.

3b74e7ec58 MPC512x: remove include/mpc512x.h
Move needed definitions (register descriptions etc.) from
include/mpc512x.h  into  include/asm-ppc/immap_512x.h.

Instead of using a #define'd register offset, use a function that
provides the PATA controller's base address.

All the rest of include/mpc512x.h are register offset definitions
which can be eliminated by proper use of C structures.

There are only a few register offsets remaining that are needed in
cpu/mpc512x/start.S; for these we provide cpu/mpc512x/asm-offsets.h
which is intended as a temporary workaround only. In a later patch
this file will be removed, too, and then auto-generated from the
respective C structs.

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
line, but "No additional help available." which is not exactly wrong,
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

	Usage:
	dtt         - Read temperature from digital thermometer and thermostat.

After:
	=> help dtt
	dtt - Read temperature from Digital Thermometer and Thermostat

	Usage:
	dtt

Also, providing default functions will allow all boards to enable

ef11df6b66 mpc5121: squash some fdt fixup errors
On ADS5121 when booting linux the following errors are seen:
    Unable to update property /soc5121@80000000:bus-frequency, err=FDT_ERR_NOTFOUND
    Unable to update property /soc5121@80000000/ethernet@2800:local-mac-address, err=FDT_ERR_NOTFOUND
    Unable to update property /soc5121@80000000/ethernet@2800:address, err=FDT_ERR_NOTFOUND

This is caused by ft_cpu_setup trying to deal with
both old and new soc node naming.  This patch
fixes this by being smarter about what to
fixup.

Also do soc node fixups by compatible instead of by path.
A new board config called OF_SOC_COMPAT defined
to be "fsl,mpc5121-immr" replaces the old
OF_SOC node path that was defined to be "soc@80000000".

Old device trees still work, but the compatiblity
is conditional on CONFIG_OF_SUPPORT_OLD_DEVICE_TREES
which is on by default in include/configs/ads5121.h.

contents of a buffer descriptor without the 'LAST' bit set, so the first

safely combine the two pieces into the whole frame.
