c48c895433 am33xx: Document what we're doing with ddrctrl->ddrckectrl
- Remove the call to set ddrctrl->ddrioctrl as it's all zeros.
- Comment what we're really setting in ddrctrl->ddrckectrl which is that
  we're operating in the normal mode where EMIF/PHY clock is controlled
  by the PHY.

c8da4a587c am33xx: Clean up unused DDR defines, prefix more with 'DDR2'
- Remove a handful of unused defines.
- Prefix more values with 'DDR2' as DDR3 will require different values.

b971dfad6a am33xx: Move the call to ddr_pll_config, make it take the frequency
Depending on if we have DDR2 or DDR3 on the board we will need to call
ddr_pll_config with a different value.  This call can be delayed
slightly to the point where we know which type of memory we have.

fda35eb982 am33xx: Pass to config_ddr the type of memory that is connected
We need to pass in the type of memory that is connected to the board.
The only reliable way to do this is to know what type of board we are
running on (which later will be knowable in s_init()).  For now, pass in
the value of DDR2.

bce58fece5 am33xx: Make config_cmd_ctrl / config_ddr_data take const structs
Rework the EMIF4/DDR code slightly to setup the structs that
config_cmd_ctrl and config_ddr_data take to be setup at compile time and
mark them as const.  This lets us simplify the calling path slightly as
well as making it easier to deal with DDR3.

10e7e36daf am33xx: Rework DDR2 EMIF initalization slightly
With the previous bugfix we now don't need to set two different REF_CTRL
values and instead set the final value.

372f11f58d am33xx: Bugfix to config_sdram()
When we change SDRAM_CONFIG this triggers a refresh based on all of the
parameters that we have programmed so we must do this last.

13f1c44bc5 am33xx: Remove extra check in enable_ddr_clocks
We do not need to check for EMIF_GCLK and L3_GCLK being active.  This
was a hold-over from bringup and no longer required.

3b97152b63 omap: am33xx: enable gpio support
This patch uses the code in omap-common to support gpio modules 1-3
on am33xx based boards.

It adds base address and register definitions, enables clocks to the
modules, and enables building the common gpio code for CONFIG_AM33XX
as well as CONFIG_OMAP

bbbc1ae921 ARM:OMAP+:MMC: Add parameters to MMC init
Add parameters to the OMAP MMC initialization function so the board can
mask host capabilities and set the maximum clock frequency.  While the
OMAP supports a certain set of MMC host capabilities, individual boards
may be more restricted and the OMAP may need to be configured to match
the board.  The PRG_SDMMC1_SPEEDCTRL bit in the OMAP3 is an example.
