1e463866f5 omap4: automatic sdram detection
Identify SDRAM devices connected to EMIF automatically:
LPDDR2 devices have some Mode Registers that provide details
about the device such as the type, density, bus width
etc. EMIF has the capability to read these registers. If there
are no devices connected to a given chip-select reading mode
registers will return junk values. After reading as many such
registers as possible and matching with expected ranges of
values the driver can identify if there is a device connected
to the respective CS. If we identify that a device is connected
the values read give us complete details about the device.

This along with the base AC timings specified by JESD209-2
allows us to do a complete automatic initialization of
SDRAM that works on all boards.

Please note that the default AC timings specified by JESD209-2
will be safe for all devices but not necessarily optimal. However,
for the Elpida devices used on Panda and SDP the default timings
are both safe and optimal.

095aea293b omap4: calculate EMIF register values
Calculate EMIF register values based on AC timing parameters
from the SDRAM datasheet and the DDR frequency rather than
using the hard-coded values.

For a new board the user doen't have to go through the tedious
process of calculating the register values. Instead, just
provide the AC timings from the device data sheet as input
and the driver will automatically calculate the register values.

d2f18c275e omap4: utility function to identify the context of hw init
The basic hardware init of OMAP4(s_init()) can happen in 4
different contexts:
 1. SPL running from SRAM
 2. U-Boot running from FLASH
 3. Non-XIP U-Boot loaded to SDRAM by SPL
 4. Non-XIP U-Boot loaded to SDRAM by ROM code using the
    Configuration Header feature

What level of hw initialization gets done depends on this
context. Add a utility function to find this context.
