The original nandbcb tool was designed for imx6 only, when trying to
leverage it to replace the kobs-ng tool, we found the design is not
friendly for supporting all platforms. To support all iMX6/7/8 platforms
and for easy further maintain, I reconstruct the structure of the tool.
The main changes including:
1. Use platform_data to determine the logic branches rather than simply
use SOC name.
2. More data structures as parameter for functions.
3. Global variables to define the FCB/DBBT/FW locations.
4. Implement the kobs-ng default 4 FCB/4 DBBT/2 FW layout.
5. Support Hamming coding/ 40bit BCH/ 62bit BCH coding FCB.
6. Dump and compare all written FCB/DBBT to verify data integrity.
The tool has been verified on iMX6Q/DL, 6SX, 7D, 6ULL, iMX8QX, iMX8MM.

Tested on i.MX8MM EVK, imx8mm evk uses BCH
encoding and randomizer
modify macro and print size_t with %zx
use CONFIG_IMX8M because it should apply to imx8mq/mm/mn

bchtype in FCB should be associated to the gf_13/14 settings in BCH, fix
the issue and test on Micron 29F64G08CBABB, it can boot after the
change.

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.
Move the compatibility features into a separate header file.

At present devres.h is included in all files that include dm.h but few
make use of it. Also this pulls in linux/compat which adds several more
headers. Drop the automatic inclusion and require files to include devres
themselves. This provides a good indication of which files use devres.

The 'sf' command is not supposed to rely on the MTD stack, but both
'sf' and 'nand' commands use helpers located in mtd_uboot.c. Despite
their location, these functions do not depend at all on the MTD
stack.
This file (drivers/mtd/mtd_uboot.c) is only compiled if CONFIG_MTD is
selected, which is inconsistent with the current situation. Solve this
by moving these three functions (which are only used by the above two
commands) out of mtd_uboot.c and put them in a C file only compiled
with cmd/sf.c and cmd/nand.c.

Add subcommand for add writing BCB only, where we provide appropriate
offsets for firmware1 and firmware2 and size.
Example of usage:
> nandbcb bcbonly 0x00180000 0x00080000 0x00200000
Writing 1024 bytes to 0x0: randomizing
OK
Writing 1024 bytes to 0x20000: randomizing
OK

Writing/updating boot image in nand device is not
straight forward in i.MX6 platform and it requires
boot control block(BCB) to be configured.
It becomes difficult to use uboot 'nand' command to
write BCB since it requires platform specific attributes
need to be taken care of.
It is even difficult to use existing msx-nand.c driver by
incorporating BCB attributes like mxs_dma_desc does
because it requires change in mtd and nand command.
So, cmd_nandbcb implemented in arch/arm/mach-imx
BCB contains two data structures, Firmware Configuration Block(FCB)
and Discovered Bad Block Table(DBBT). FCB has nand timings,
DBBT search area, page address of firmware.
On summary, nandbcb update will
- erase the entire partition
- create BCB by creating 2 FCB/DBBT block followed by
1 FW block based on partition size and erasesize.
- fill FCB/DBBT structures
- write FW/SPL on FW1
- write FCB/DBBT in first 2 blocks
for nand boot, up on reset bootrom look for FCB structure in
first block's if FCB found the nand timings are loaded for
further reads. once FCB read done, DTTB will load and finally
firmware will be loaded which is boot image.
Refer section "NAND Boot" from doc/imx/common/imx6.txt for more usage
information.
