GPMC controller on TI's OMAP SoC is general purpose controller to interface
with different types of external devices like;
- parallel NOR flash
- parallel NAND flash
- OneNand flash
- SDR RAM
- Ethernet Devices like LAN9220
Though GPMC configurations may be different for each platform depending on
clock-frequency and external device interfacing with controller. But
initialization sequence remains common across all platfoms.
Thus this patch merges gpmc_init() scattered in different arch-xx/mem.c
files into single omap-common/mem-common.c
However, actual platforms specific register config values are still sourced
from corresponding platform specific headers like;
AM33xx: arch/arm/include/asm/arch-am33xx/mem.h
OMAP3: arch/arm/include/asm/arch-omap3/mem.h
OMAP4: arch/arm/include/asm/arch-omap4/mem.h
OMAP4: arch/arm/include/asm/arch-omap5/mem.h
Also, CONFIG_xx passed by board-profile decide config for which set of macros
need to be used for initialization
CONFIG_NAND: initialize GPMC for NAND device
CONFIG_NOR: initialize GPMC for NOR device
CONFIG_ONENAND: initialize GPMC for ONENAND device

This patch moves platform specific information for GPMC and ELM controller
into separate header files, so that any derivative devices do not mess other
header files.
Platform specific information added into arch-xx/../hardware.h
- CPU related platform specific details like base-address of GPMC and ELM
Platform specific information added into arch-xx/../mem.h
- Generic configs for GPMC and ELM initialization.
- Hardware parameters or constrains specific to GPMC and ELM IP like;
number of max number of chip-selects available

omap4: allow the use of a plain text env file instead boot scripts
For production systems it is better to use script images since
they are protected by checksums and carry valuable information like
name and timestamp. Also, you can't validate the content passed to
env import.
But for development, it is easier to use the env import command and
plain text files instead of script-images.
Since both OMAP4 supported boards (Panda and TI SDP4430) are used
primarily for development, this patch allows U-Boot to load env var
from a text file in case that an boot.scr script-image is not present.
The variable uenvcmd (if existent) will be executed (using run) after
uEnv.txt was loaded. If uenvcmd doesn't exist the default boot sequence
will be started.

Some device types (e.g. eMMC) have hardware-level partitions (for eMMC,
separate boot and user data partitions). This change allows the user to
specify the HW partition they wish to access when passing a device ID to
U-Boot Commands such as part, ls, load, ums, etc.
The syntax allows an optional ".$hwpartid" to be appended to the device
name string for those commands.
Existing syntax, for MMC device 0, default HW partition ID, SW partition
ID 1:
ls mmc 0:1 /
New syntax, for MMC device 0, HW partition ID 1 (boot0), SW partition
ID 2:
ls mmc 0.1:2 /
For my purposes, this is most useful for the ums (USB mass storage
gadget) command, but there's no reason not to allow the new syntax
globally.
This patch adds the core support infra-structure. The next patch will
provide the implementation for MMC.

This sub-command adds support for the RPMB partition of an eMMC:
* mmc rpmb key <address of the authentication key>
Programs the authentication key in the eMMC This key can not
be overwritten.
* mmc rpmb read <address> <block> <#count> [address of key]
Reads <#count> blocks of 256 bytes in the RPMB partition
beginning at block number <block>. If the optionnal
address of the authentication key is provided, the
Message Authentication Code (MAC) is verified on each
block.
* mmc rpmb write <address> <block> <#count> <address of key>
Writes <#count> blocks of 256 bytes in the RPMB partition
beginning at block number <block>. The datas are signed
with the key provided.
* mmc rpmb counter
Returns the 'Write counter' of the RPMB partition.
The sub-command is conditional on compilation flag CONFIG_SUPPORT_EMMC_RPMB

When configure the fsl_esdhc driver to PIO mode by defining
"CONFIG_SYS_FSL_ESDHC_USE_PIO", the SD/MMC read and write will fail.
Two bugs in the driver to cause the issue:
1. The read buffer was invalidated after reading from DATAPORT register,
which should be only applied to DMA mode. The valid data in cache was
overwritten by physical memory.
2. The watermarks are not set in PIO mode, will cause according state not
