278b90ce78 configs: Migrate CONFIG_SYS_TEXT_BASE
On the NIOS2 and Xtensa architectures, we do not have
CONFIG_SYS_TEXT_BASE set.  This is a strict migration of the current
values into the defconfig and removing them from the headers.

I did not attempt to add more default values in and for now will leave
that to maintainers.

7dd97af523 powerpc: Drop unreferenced CONFIG_* defines
The following config symbols are only defined once and never referenced
anywhere else:

CONFIG_CYRUS
CONFIG_IDS8313
CONFIG_MPC8308_P1M
CONFIG_MPC8308RDB
CONFIG_MPC8349EMDS
CONFIG_MPC8349ITXGP
CONFIG_SBC8349
CONFIG_SBC8548
CONFIG_SBC8641D
CONFIG_TQM834X
CONFIG_VE8313
CONFIG_XPEDITE5140
CONFIG_XPEDITE5200
CONFIG_XPEDITE550X

Most of them are config symbols named after the respective boards which
seems to have been a standard practice at some point.

e090579d0a include/configs: remove numerous CONFIG_SYS_BARGSIZE definitions
This commit removes definitions of CONFIG_SYS_BARGSIZE defined to be
equal to CONFIG_SYS_CBSIZE in numerous configuration files.

We remove such definitions in two situations:

 - CONFIG_SYS_CBSIZE is otherwise not defined in the board
   configuration file, which means the default value of
   CONFIG_SYS_CBSIZE == 256 applies. In this case, the default value
   of CONFIG_SYS_BARGSIZE == 512 (common/image.c) is suitable, as it is
   larger.

 - CONFIG_SYS_CBSIZE is defined in the board configuration file, but
   to a value equal or less than 512. In this case, the default value
   of CONFIG_SYS_BARGSIZE == 512 (common.image.c) is suitable, as it
   is equal or larger.

73223f0e1b Kconfig: Move CONFIG_FIT and related options to Kconfig
There are already two FIT options in Kconfig but the CONFIG options are
still in the header files. We need to do a proper move to fix this.

Move these options to Kconfig and tidy up board configuration:

   CONFIG_FIT
   CONFIG_OF_BOARD_SETUP
   CONFIG_OF_SYSTEM_SETUP
   CONFIG_FIT_SIGNATURE
   CONFIG_FIT_BEST_MATCH
   CONFIG_FIT_VERBOSE
   CONFIG_OF_STDOUT_VIA_ALIAS
   CONFIG_RSA

Unfortunately the first one is a little complicated. We need to make sure
this option is not enabled in SPL by this change. Also this option is
enabled automatically in the host builds by defining CONFIG_FIT in the
image.h file. To solve this, add a new IMAGE_USE_FIT #define which can
be used in files that are built on the host but must also build for U-Boot
and SPL.

Note: Masahiro's moveconfig.py script is amazing.

3e3262bd14 sbc8548: enable support for hardware SPD errata workaround
Existing boards by default have an issue where the LBC SDRAM
SPD EEPROM and the DDR2 SDRAM SPD EEPROM both land at 0x51.

After the hardware modification listed in the README is made,
then the DDR2 SPD EEPROM appears at 0x53.  So this implements
a board specific get_spd() by taking advantage of the existing
weak linkage, that 1st tries reading at 0x53 and then if that
fails, it falls back to the old 0x51.

Since the old dependency issue of "SPD implies no LBC SDRAM"
gets removed with the hardware errata fix, remove that restriction
in the code, so both LBC SDRAM and SPD can be selected.

2a6b3b74d8 sbc8548: relocate fixed ddr init code to ddr.c file
Nothing to see here, just a relocation of the fixed ddr init
sequence to live in the actual ddr.c file itself.

7e44f2b710 sbc8548: Make enabling SPD RAM configuration work
Previously, SPD configuration of RAM was non functional on
this board.  Now that the root cause is known (an i2c address
conflict), there is a simple end-user workaround - remove the
old slower local bus 128MB module and then SPD detection on the
main DDR2 memory module works fine.

We make the enablement of the LBC SDRAM support conditional on
being not SPD enabled.  We can revisit this dependency as the
hardware workaround becomes available.

Turning off LBC SDRAM support revealed a couple implict dependencies
in the tlb/law code that always expected an LBC SDRAM address.

This has been tested with the default 256MB module, a 512MB
a 1GB and a 2GB, of varying speeds, and the SPD autoconfiguration
worked fine in all cases.

The default configuration remains to go with the hard coded
DDR config, so the default build will continue to work on boards
where people don't bother to read the docs.  But the advantage
of going to the SPD config is that even the small default module
gets configured for CL3 instead of CL4.

5f4c6f0db9 sbc8548: Fix LBC SDRAM initialization settings
These were cloned from the mpc8548cds platform which has
a different memory layout (1/2 the size).  Set the values
by comparing to the register file for the board used during
JTAG init sequence:

	LSDMR1		0x2863B727	/* PCHALL */
	LSDMR2		0x0863B727	/* NORMAL */
	LSDMR3		0x1863B727	/* MRW    */
	LSDMR4		0x4063B727	/* RFEN   */

This differs from what was there already in that the RFEN is
not bundled in all four steps implicitly, but issued once
as the final step.

The other difference seen when comparing vs. the register file init,
is that since the memory is split across /CS3 and /CS4, the dummy
writes need to go to 0xf000_0000 _and_ to 0xf400_0000.

We also rewrite the final LBC SDRAM inits as macros, as there is
no real need for them to be a local variable that is modified
on the fly at runtime.
