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)

beba5f04f2 mtd: nand: omap: make am33xx/elm.c as common driver for all OMAPx and AMxxxx platforms
ELM hardware engine which is used for ECC error detection, is present on all
latest OMAP SoC (like OMAP4xxx, OMAP5xxx, DRA7xxx, AM33xx, AM43xx). Thus ELM
driver should be moved to common drivers/mtd/nand/ folder so that all SoC
having on-chip ELM hardware engine can re-use it.
This patch has following changes:
- mv arch/arm/include/asm/arch-am33xx/elm.h arch/arm/include/asm/omap_elm.h
- mv arch/arm/cpu/armv7/am33xx/elm.c drivers/mtd/nand/omap_elm.c
- update Makefiles
- update #include <asm/elm.h>
- add CONFIG_NAND_OMAP_ELM to compile driver/mtd/nand/omap_elm.c
	and include in all board configs using AM33xx SoC platform.

56eb3da43f arm, am335x: update for the siemens boards
- dxr2: define unused pins as input
- do not enable RTC32K OSC on dxr2 board
- update default environment
  - add splashpos=m,m to default environment, so splash screen is always
    centered.
  - adapt environment for bootcount feature
  - add altbootcmd to default environment
- rut: SPL add early reset pulse for eth-phy, maXTouch and display
- rut: display timing aenderungen
- siemens boards: adapt for background color = white
- add boutcount feature for the siemens boards
  store the bootcount in the environment, as we have no softreset
  save registers on this hardware. Use therefore the CONFIG_BOOTCOUNT_ENV
  bootcount driver.
- change spi mode from 3 to 0 for the lcd init
- add gpio pin for lcd reset with state 0 and add mdelay
- siemens boards: use own USB id's
- add dfu serial and device number for siemens boards
  Add for the siemens boards the possibility to define in dfu mode,
  the iSerialNumber and the bcdDevice fields in the USB Device
  descriptor.
- fix upgrade mechanism based on bootcount
  Correct location of saveenv and remove not active variable.

  Add CONFIG_BOOT_RETRY_TIME and CONFIG_RESET_TO_RETRY to
  reboot board in case of empty kernel partition. Without
  these defines an empty kernel partition leads to an
  abort of boot process and one remains in u-boot prompt.

- general cleanup of dxr2, pxm2 and rut boards
  all:
   * Remove net boot from bootcmd
     Ping can cause a crash on boards without ethernet phy.
     net_nfs command is used only for development

   * Add reset at the end of bootcmd
     In order to have an immediate reset of the boot when bootcmd
     fails, add reset at the end of bootcmd.

  rut:
   * add nand_img_size

  dxr2:
   * update nand_img_size

   * ddr3 timings updated with iocontrol property that can be
     modified via eeprom. New default parameters from software
     leveling with draco ES2.
