The use of 'bool' data types in globally used header files cases build
errors like this:

In file included from arch/blackfin/include/asm/blackfin.h:13:0,
                 from include/common.h:92,
                 from cmd_test.c:17:
arch/blackfin/include/asm/blackfin_local.h:54:1: error: unknown type name 'bool'

Use plain 'int' instead to avoid such kind of trouble.

Very often a constant pointer is passed to this function, so we should
declare this, since map_to_sysmem() does not change the pointer.

Sandbox uses an emulated memory map which is quite small. We don't need the
CONFIG_PHYS_64BIT option since we can address memory with a 32-bit offset
into our ram_buf.

Adjust the phys_addr_t and phys_size_t types accordingly.

This file must be compiled with system headers, even if U-Boot has headers
of the same name. The existing solution for this is good enough for libfdt,
but fails when we have headers like stdint.h in U-Boot.

Use -idirafter instead of -I, and remove the -nostdinc and other things
that we don't want for this file. The best way to do this is to keep a
copy of the original flags, rather than trying to filter them later.

The uint64_t type is defined in linux/types.h, so is safer than u64, which
is not actually a Linux type.

GPMC controller is common IP to interface with both NAND and NOR flash devices.
Also, it supports max 8 chip-selects, which can be independently connected to
any of the devices.
But ROM code expects the boot-device to be connected to only chip-select[0].
Thus to resolve conflict between NOR and NAND boot. This patch:
- combines NOR and NAND configs spread in board files to common gpmc_init()
- configures GPMC based on boot-mode selected for SPL boot.

BCH8_ECC scheme implemented in omap_gpmc.c driver has following favours
+-----------------------------------+-----------------+-----------------+
|ECC Scheme                         | ECC Calculation | Error Detection |
+-----------------------------------+-----------------+-----------------+
|OMAP_ECC_BCH8_CODE_HW              |GPMC             |ELM H/W engine   |
|OMAP_ECC_BCH8_CODE_HW_DETECTION_SW |GPMC             |S/W BCH library  |
+-----------------------------------+-----------------+-----------------+

Current implementation limits the BCH8_CODE_HW only for AM33xx device family.
(using CONFIG_AM33XX). However, other SoC families (like TI81xx) also have
ELM hardware module, and can support ECC error detection using ELM.

This patch
- removes CONFIG_AM33xx
	Thus this driver can be reused by all devices having ELM h/w engine.
- adds omap_select_ecc_scheme()
	A common function to handle ecc-scheme related configurations. This
	can be used both during device-probe and via user-space u-boot commads
	to change ecc-scheme. During device probe ecc-scheme is selected based
	on CONFIG_NAND_OMAP_ELM or CONFIG_NAND_OMAP_BCH8
- enables CONFIG_BCH
	S/W library (lib/bch.c) required by OMAP_ECC_BCHx_CODE_HW_DETECTION_SW
  	is enabled by CONFIG_BCH.
- enables CONFIG_SYS_NAND_ONFI_DETECTION
	for auto-detection of ONFI compliant NAND devices
- updates following README doc
	doc/README.nand
	board/ti/am335x/README
	doc/README.omap3
