Traditionally many boards used local definitions for SRAM base address
and size (like SRAM_BASE, SRAM_LEN and/or SRAM_SIZE), while the (now)
"official" names are CONFIG_SYS_SRAM_BASE and CONFIG_SYS_SRAM_SIZE.

The corresponding code in arch/powerpc/lib/board.c was board specific,
and has never actually been maintained well. Replace this by feature-
specific code and adapt the boards that actually use this.

NOTE: there is still a ton of boards using the old #defines, which
therefor contain incorrect values in bi_sramstart and bi_sramsize.

All respective board maintainers are requested to clean up their
respective configurations.  Thanks.

A number of boards define CONFIG_SYS_SRAM_BASE but fail to define
CONFIG_SYS_SRAM_SIZE which is needed when cleaning up the code that
prints this information with the bdinfo command.

Add the missing deinitions.

Commit 54841ab5 made the argv parameter

set to point to the global data structure and relies on argv being non-

With this patch, do_go_exec() creates a new copy of the argv array with
an extra element to store global data pointer rather than simply
clobbering an arbitrary memory location.

On OMAP34xx ES1.0, the L2 enable bit can only be set in secure mode,
so an SMC call to the ROM monitor is required.  On later versions,
and on newer devices, this bit is banked and we can set it directly.

The code checked only the ES revision of the chip, and hence incorrectly
used the ROM call on ES1.0 versions of other devices.

This patch adds a check for chip family as well as revision, and also
removes some code duplication between the enable and disable functions.
