Current MXC NAND driver uses memory BBT, it will create memory BBT in each
booting by searching bad blocks.This patch enables the flash BBT, so the NAND driver can read back Bad block

Current SPI flash framework only supports to set bank register
(CONFIG_SPI_FLASH_BAR) for flash with size > 16MiB. But some new flash device
(for example, mt35xu512g) does not support this way, it only supports
4bytes extend address.To access the whole memory size for such flash device, we add the support
for this 4bytes extend address mode to SPI flash framework.
The configuration CONFIG_SPI_FLASH_4BYTES_ADDR is used to enable the feature.Signed-off-by: Ye Li

i.MX6QP and i.MX7D BCH module integrated a new feature to detect the
bitflip number for erased NAND page. So for these two platform, set the
erase threshold to gf/2 and if bitflip detected, GPMI driver will
correct the data to all 0xFF.Also updated the imx6qp dts file to ditinguish the GPMI module for i.MX6Q
with the one for i.MX6QP.
"In this patch, i.MX6UL is added and threshold changed to use ecc_strength.

The cod change updated the NAND driver BCH ECC layout algorithm to
support large oob size NAND chips(oob > 1024 bytes).Current implementation requires each chunk size larger than oob size so
the bad block marker (BBM) can be guaranteed located in data chunk. The
ECC layout always using the unbalanced layout(Ecc for both meta and
Data0 chunk), but for the NAND chips with oob larger than 1k, the driver
cannot support because BCH doesn’t support GF 15 for 2K chunk.The change keeps the data chunk no larger than 1k and adjust the ECC
strength or ECC layout to locate the BBM in data chunk. General idea for
large oob NAND chips is1.Try all ECC strength from the minimum value required by NAND spec to
the maximum one that works, any ECC makes the BBM locate in data chunk
can be chosen.2.If none of them works, using separate ECC for meta, which will add one
extra ecc with the same ECC strength as other data chunks. This extra
ECC can guarantee BBM located in data chunk, of course, we need to check
if oob can afford it.Signed-off-by: Han Xu

The variable cfi_flash_num_flash_banks is defined iff
CONFIG_SYS_MAX_FLASH_BANKS_DETECT is defined, but it is used
unconditionally in the function cfi_flash_init_dm. This leads to a
undefined variable compile error when CONFIG_SYS_MAX_FLASH_BANKS_DETECT
is not defined, but DM is enabled.Fix this by always defining the cfi_flash_num_flash_banks variable.
