The AM33xx emif4/ddr support closely matches what is need to support
TI814x except that TI814x has two EMIF instances. Refactor all the
emif4 helper calls and the config_ddr() init function to use an
additional instance number argument.

From: Matt Porter @ 2013-03-15 20:07 UTC (permalink / raw)
To: u-boot
Split clock.c for am335x and ti814x and add ti814x specific
clock support.
Signed-off-by: Matt Porter <mporter@ti.com>
---
v4: no changes
v3:
* Fix EMIF/L3F clock enable ordering issue
(Exposed on UART boot with hang at check for L3F enabled)
v2:
* remove unused dmtimer support
* add register structs bit definitions
* rename soc-specific clock files for consistency
* move ti814x specific defs to clock_ti814x.c
* move am335x specific defs to clock_am335x.c
* fix copyright date
* remove clocks_*.h and go back to clock.h

AM33XX and TI814X have a similar mux though the pinmux register
layout and address space differ. Add a separate ti814x mux include
to support the TI814X-specific differences.
