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.

The basic hardware init of OMAP4(s_init()) can happen in 4
different contexts:

2. U-Boot running from FLASH

4. Non-XIP U-Boot loaded to SDRAM by ROM code using the

Some of the LPSC constants were incorrect, and some were missing. This
commit fixes the incorrect constants (which were not used anywhere in
the tree) and adds all constants for both DA830 and DA850, as per the
TI datasheets.
There are two main sets of LPSC constants, depending on the processor
family. The DA8xx constants were given in an enum whereas the non-DA8xx
constants were preprocessor defines. This commit switches the DA8xx
constants to defines for consistency.
The function davinci_emac_mii_mode_sel() is defined in
board/davinci/common/misc.c for any DA8xx CPU which has
CONFIG_DRIVER_TI_EMAC enabled. However, the prototype was only being
declared in <include/asm/arch/davinci_misc.h> for the DA850 EVM board.
This patch declares it for all DA8xx CPUs where CONFIG_DRIVER_TI_EMAC
is enabled.
Add a generic GPIO driver for the DaVinci DA8xx processors. It is turned
on by defining CONFIG_DA8XX_GPIO and fulfills the generic GPIO interface
specified in <asm/gpio.h> . The driver has support for both manipulating
GPIO pins as well as automatically configuring the pin multiplexor
registers to set the pin function to GPIO.
In preparation for a generic GPIO driver for the DA8xx processors,
rename <asm/arch/gpio_defs.h> to <asm/arch/gpio.h> and fix up all files
which include it.
