434f2cfcad ARM: omap: move board specific NAND configs out from ti_armv7_common.h
This patch moves some board specific NAND configs:
- FROM: generic config file 'ti_armv7_common.h'
- TO:   individual board config files using these configs.
So that each board can independently set the value as per its design.

Following configs are affected in this patch:
  CONFIG_SYS_NAND_U_BOOT_OFFS: <refer doc/README.nand>
  CONFIG_CMD_SPL_NAND_OFS: <refer doc/README.falcon>
  CONFIG_SYS_NAND_SPL_KERNEL_OFFS: <refer doc/README.falcon>
  CONFIG_CMD_SPL_WRITE_SIZE: <refer doc/README.falcon>

This patch also updates documentation for few of above NAND configs.

222a3113b4 ARM: omap: clean redundant PISMO_xx macros used in OMAP3
PISMO_xx macros were used to define 'Platform Independent Storage MOdule'

12cc543767 omap3: overo: Select fdtfile for expansion board
The u-boot Overo board actually supports both Overo (OMAP35xx)
and Overo Storm (AM/DM37xx) COMs with a range of different expansion
boards.  This provides a mechanism to select the an appropriate device
tree file based on the processor version and, if available, the
expansion board ID written on the expansion board EEPROM. To match the
3.15+ kernels, fdtfile names have this format:
 "omap3-overo[-storm]-<expansion board name>.dtb"

By default, we use "omap3-overo-storm-tobi.dtb".

b80a660338 mtd: nand: omap: add CONFIG_SYS_NAND_BUSWIDTH_16BIT to indicate NAND device bus-width
GPMC controller needs to be configured based on bus-width of the NAND device
connected to it. Also, dynamic detection of NAND bus-width from on-chip ONFI
parameters is not possible in following situations:
SPL:    SPL NAND drivers does not support ONFI parameter reading.
U-boot: GPMC controller iniitalization is done in omap_gpmc.c:board_nand_init()
        which is called before probing for devices, hence any ONFI parameter
        information is not available during GPMC initialization.

Thus, OMAP NAND driver expected board developers to explicitely write GPMC
configurations specific to NAND device attached on board in board files itself.
But this was troublesome for board manufacturers as they need to dive into
lengthy platform & SoC documents to find details of GPMC registers and
appropriate configurations to get NAND device working.

This patch instead adds existing CONFIG_SYS_NAND_BUSWIDTH_16BIT to board config
hich indicates that connected NAND device has x16 bus-width. And then based on
this config GPMC driver itself initializes itself based on NAND bus-width. This
keeps board developers free from knowing GPMC controller specific internals.

0b3fde1136 omap: overo: allow the use of a plain text env file instead boot scripts
Adapted from d70f5480 described below.

    commit d70f54808d
    Author: Javier Martinez Canillas <javier@dowhile0.org>
    Date:   Mon Jan 7 03:51:20 2013 +0000

    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.

a7e36fc95f mtd: nand: omap: remove unused #defines from common omap_gpmc.h
OMAP NAND driver can detect Page-size and OOB-size of NAND device from ONFI
params or nand_id[] table. And based on that it defines ECC layout.
This patch
1) removes following board configs used for defining NAND ECC layout
	- GPMC_NAND_ECC_LP_x16_LAYOUT (for large page x16 NAND)
	- GPMC_NAND_ECC_LP_x8_LAYOUT  (for large page x8 NAND)
	- GPMC_NAND_ECC_SP_x16_LAYOUT (for small page x16 NAND)
	- GPMC_NAND_ECC_SP_x8_LAYOUT  (for small page x8 NAND)

2) removes unused #defines in common omap_gpmc.h depending on above configs

Build tested using: ./MAKEALL -s am33xx -s omap3 -s omap4 -s omap5

3f719069c8 mtd: nand: omap: add CONFIG_NAND_OMAP_ECCSCHEME for selection of ecc-scheme
This patch adds new CONFIG_NAND_OMAP_ECCSCHEME, replacing other distributed
CONFIG_xx used for selecting NAND ecc-schemes.
This patch aims at solving following issues.

1) Currently ecc-scheme is tied to SoC platform, which prevents user to select
   other ecc-schemes also supported in hardware. like;
 - most of OMAP3 SoC platforms use only 1-bit Hamming ecc-scheme, inspite
   the fact that they can use higher ecc-schemes like 8-bit ecc-schemes with
   software based error detection (OMAP_ECC_BCH4_CODE_HW_DETECTION_SW).
 - most of AM33xx SoC plaforms use 8-bit BCH ecc-scheme for now, but hardware
   supports BCH16 ecc-scheme also.

2) Different platforms use different CONFIG_xx to select ecc-schemes, which
   adds confusion for user while migrating platforms.
 - *CONFIG_NAND_OMAP_ELM* which enables ELM hardware engine, selects only
    8-bit BCH ecc-scheme with h/w based error-correction (OMAP_ECC_BCH8_CODE_HW)
    whereas ELM hardware engine supports other ecc-schemes also like; BCH4,
    and BCH16 (in future).
 - *CONFIG_NAND_OMAP_BCH8* selects 8-bit BCH ecc-scheme with s/w based error
    correction (OMAP_ECC_BCH8_CODE_HW_DETECTION_SW).
 - *CONFIG_SPL_NAND_SOFTECC* selects 1-bit Hamming ecc-scheme using s/w library

Thus adding new *CONFIG_NAND_OMAP_ECCSCHEME* de-couples ecc-scheme dependency
on SoC platform and NAND driver. And user can select ecc-scheme independently
foreach board.
However, selection some hardware based ecc-schemes (OMAP_ECC_BCHx_CODE_HW) still
depends on presence of ELM hardware engine on SoC. (Refer doc/README.nand)

This allows the user can easily add extra kernel arguments. Very helpful
for reserving memory for the DSP without rewriting the entire kernel

boot_flash_type was totally unused. The other ones were actually constants, so
they have been replaced with #defines in the board config files.

25ddd1fb0a Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value
CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
being able to use "sizeof(struct global_data)" in assembler files.
Recent experience has shown that manual synchronization is not
reliable enough.  This patch renames CONFIG_SYS_GBL_DATA_SIZE into
GENERATED_GBL_DATA_SIZE which gets automatically generated by the
asm-offsets tool.  In the result, all definitions of this value can be
deleted from the board config files.  We have to make sure that all
files that reference such data include the new <asm-offsets.h> file.

No other changes have been done yet, but it is obvious that similar
changes / simplifications can be done for other, related macro
definitions as well.
