This adds a SPI flash driver which simulates SPI flash clients.
Currently supports the bare min that U-Boot requires: you can
probe, read, erase, and write. Should be easy to extend to make
it behave more exactly like a real SPI flash, but this is good
enough to merge now.

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)

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

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.

nand_ecclayout is present in mtd.h at Linux.
Move this structure to mtd.h to comply with Linux.
Also, increase the ecc placement locations to 640 to suport device having
writesize/oobsize of 8KB/640B. This means that the maximum oobsize has gone
up to 640 bytes and consequently the maximum ecc placement locations have
also gone up to 640.
Changes from Prabhabkar's version (squashed into one patch to preserve
bisectability):
- Added _LARGE to MTD_MAX_*_ENTRIES
This makes the names match current Linux source, and resolves
a conflict between
http://patchwork.ozlabs.org/patch/280488/
and
http://patchwork.ozlabs.org/patch/284513/
The former was posted first and is closer to matching Linux, but
unlike Linux it does not add _LARGE to the names. The second adds
_LARGE to one of the names, and depends on it in a subsequent patch
(http://patchwork.ozlabs.org/patch/284512/).
- Made max oobfree/eccpos configurable, and used this on tricorder,
alpr, ASH405, T4160QDS, and T4240QDS (these boards failed to build
for me without doing so, due to a size increase).
On tricorder SPL, this saves 2576 bytes (and makes the SPL build
again) versus the new default of 640 eccpos and 32 oobfree, and
saves 336 bytes versus the old default of 128 eccpos and 8 oobfree.

This allows you to write data to an UBI volume when the amount of memory
available to write that data from is less than the total size of the
data. For example, you may split a root filesystem UBIFS image into
parts, provide the total size of the image to the first write.part
command and then use multiple write.part commands to write the
subsequent parts of the volume. This results in a sequence of commands
akin to:
ext4load mmc 0:1 0x80000000 rootfs.ubifs.0
ubi write.part 0x80000000 root 0x08000000 0x18000000
ext4load mmc 0:1 0x80000000 rootfs.ubifs.1
ubi write.part 0x80000000 root 0x08000000
ext4load mmc 0:1 0x80000000 rootfs.ubifs.2
ubi write.part 0x80000000 root 0x08000000
This would write 384MiB of data to the UBI volume 'root' whilst only
requiring 128MiB of said data to be held in memory at a time.

Add mkimage support for generating and verifying MXS bootstream.
The implementation here is mostly a glue code between MXSSB v0.4
and mkimage, but the long-term goal is to rectify this and merge
MXSSB with mkimage more tightly. Once this code is properly in
U-Boot, MXSSB shall be deprecated in favor of mkimage-mxsimage
support.
Note that the mxsimage generator needs libcrypto from OpenSSL, I
therefore enabled the libcrypto/libssl unconditionally.

Add support for setting the CSF (Command Sequence File) pointer
which is used for HAB (High Assurance Boot) in the imximage by
adding e.g.
CSF 0x2000
in the imximage.cfg file.
This will set the CSF pointer accordingly just after the padded
data image area. The boot_data.length is adjusted with the
value from the imximage.cfg config file.
The resulting u-boot.imx can be signed with the FSL HAB tooling.
The generated CSF block needs to be appended to the u-boot.imx.

Due to the nand SPL on some board(e.g. P1022DS)has a size limit, it can
not be more than 4K. So, the SPL cannot initialize the DDR with the SPD
code. This patch introduces TPL to enable a loader stub that is loaded
by the code from the SPL. It initializes the DDR with the SPD or other
operations.
The TPL's size is sizeable, the maximum size is decided by the memory's
size that TPL runs. It initializes the DDR through SPD code, and copys
final uboot image to DDR. So there are three stage uboot images:
* spl_boot, * tpl_boot, * final uboot image

The SPL's size is sizeable, the maximum size must not exceed the size of L2
SRAM. It initializes the DDR through SPD code, and copys final uboot image
to DDR. So there are two stage uboot images:
* spl_boot, 96KB size. The env variables are copied to L2 SRAM, so that
ddr spd code can get the interleaving mode setting in env. It loads
final uboot image from offset 96KB.
* final uboot image, size is variable depends on the functions enabled.
