These are already-documented common bindings for NAND chips. Let's
handle them in nand_base.

If NAND controller drivers need to act on this data before bringing up
the NAND chip (e.g., fill out ECC callback functions, change HW modes,
etc.), then they can do so between calling nand_scan_ident() and
nand_scan_tail().

The original commit has been slightly reworked to use the fdtdec_xxx()
helpers (instead of the of_xxxx() ones).

Modern NANDs do not guarantee that data written in raw mode will not
contain bitflips just after writing them. This is fine since the number
of bitflips should be rather low and thus fixable by the ECC engine,
but since we are reading data in raw mode to verify if they match the
input data we cannot prevent failures if some bits are flipped.

The option of using standard mode to verify the data is not acceptable
either, since one of the usage of raw mode is to allow flashing images
that do not respect the standard NAND page layout or the default ECC
config (this is the case on Allwinner platforms, where the ROM code
tests several hardcoded configs, which are not necessarily matching the
NAND characteristics).

Add an extension to the nand write.raw command allowing one to disable
the verification step.

In raw mode a full sector is to be read even if image covers part of
a sector. Number of sectors are calculated as ROUND_UP(size)/sec_size by FIT
framework. This calculation assumes that image is at the 0th offset of a sector,
which is not true always in FIT case. So, include the image offset while
calculating number of sectors.

When signing images, we repeatedly call fit_add_file_data() with
successively increasing size values to include the keys in the DTB.

Unfortunately, if large keys are used (such as 4096 bit RSA keys), this
process fails sometimes, and mkimage needs to be called repeatedly to
integrate the keys into the DTB.

This is because fit_add_file_data actually returns the wrong error
code, and the loop terminates prematurely, instead of trying again with
a larger size value.

This patch corrects the return value by fixing the return value of
fdt_add_bignum, fixes a case where an error is masked by a unconditional
setting of a return value variable, and also removes a error message,
which is misleading, since we actually allow the function to fail. A
(hopefully helpful) comment is also added to explain the lack of error
message.

This is probably related to 1152a05e ("tools: Correct error handling in
fit_image_process_hash()") and the corresponding error reported here:

As part of the startup process for boards using the SPL, the
meaning of board_init_f changed such that it should return normally
rather than calling board_init_r directly. (see
db910353 )
This was fixed in 32-bit arm, but broke when SPL was added to
64 bit arm. This fixes crt0_64 so that it calls board_init_r
during the SPL and removes the direct call from board_init_f
from the arm SPL example.

Currently flash_read completes a crucial part of the environment
device configuration, the device type (mtd_type). This is rather
confusing as flash_io calls flash_read conditionally, and one might
think flash_write, which also makes use of mtd_type, gets called
before flash_read. But since flash_io is always called with O_RDONLY
first, this is not actually the case in reality.

However, it is much cleaner to complete and verify the config early
in parse_config. This also prepares the code for further extension.
