9540c7e900 ARMV7: Fix duplicate use of "b" parameter in ACTIM_CTRLA definition
ACTIM_CTRLA macro errently passes "b" parameter to ACTIM_CTRLA_TRAS()
instead of "c".  To make usage more clear, replace all single-letter
macro parameters with more descriptive parameter names.

673283f3fc OMAP3: Add SPL support to omap3_evm
Add Hynix 200MHz timing information to <asm/arch-omap3/mem.h>.
This also changes CONFIG_SYS_TEXT_BASE to 0x80100000.

75c57a3570 OMAP3: Add SPL support to Beagleboard
This introduces 200MHz Micron parts timing information based on x-loader
to <asm/arch-omap3/mem.h> and Numonyx MCFG calculation.  The memory init
logic is also based on what x-loader does in these cases.  Note that
while previously u-boot would be flashed in with SW ECC in this case it
now must be flashed with HW ECC.  We also change CONFIG_SYS_TEXT_BASE to
0x80100000.

9ae0d55074 OMAP3 SPL: Rework memory initalization and devkit8000 support
This changes to making the board be responsible for providing the
memory initialization timings in SPL and converts the devkit8000
to this framework.  In SPL we try and initialize both CS0 and CS1.

1be1433b83 OMAP3: Add optimal SDRC autorefresh control values
This adds the optimal SDRC autorefresh control register values for
100Mhz, 133MHz, 165MHz and 200MHz clocks.  We switch to using this
to provide the default 165MHz value.

14ca3dee80 omap3: mem: Add MCFG helper macro
This adds an MCFG macro to calculate the correct value, similar to
the ACTIMA/ACTIMB macros and adds a comment that all of the potential
values here are documented in the TRM.  Then we convert the Micron
value to use this macro.

2c5b87561a omap3: mem: Move comments next to definitions
Calculations for ACTIM_CTRLA amd ACTIM_CTRLB values
are defined in 'header' style comments.

Moved them along with definitions. Should help maintain
consistency between comments and code if any of these
are tweaked in future.

e3596e35f5 omap3: mem: Define and use common macros
Define common macros to arrive at the values of registers
SDRC_ACTIM_CTRLA and SDRC_ACTIM_CTRLB for different memory
types.

This doesn't make any real change in the execution but
helps readability.

b88e42560b omap3: Configure RAM bank 0 if in SPL
OMAP3 relied on the memory config done by X-loader or Configuration Header. This
has to be reworked for the implementation of a SPL. This patch configures RAM
bank 0 if CONFIG_SPL_BUILD is set. Settings for Micron-RAM used by devkit8000
are added to mem.h

cae377b59a omap3: Consolidate SDRC related operations
Consolidated SDRC related functions into one file - sdrc.c

And also replaced sdrc_init with generic memory init
function (mem_init), this generalization of omap memory setup
is necessary to support the new emif4 interface introduced in AM3517.

819833af39 Move architecture-specific includes to arch/$ARCH/include/asm
This helps to clean up the include/ directory so that it only contains
non-architecture-specific headers and also matches Linux's directory
layout which many U-Boot developers are already familiar with.
