Change calculating of position page containing BBM
If none of BBM flags are set then function nand_bbm_get_next_page
reports EINVAL. It causes that BBM is not read at all during scanning
factory bad blocks. The result is that the BBT table is build without
checking factory BBM at all. For Micron flash memories none of these
flags are set if page size is different than 2048 bytes.
Address this regression by:
- adding NAND_BBM_FIRSTPAGE chip flag without any condition. It solves
issue only for Micron devices.
- changing the nand_bbm_get_next_page_function. It will return 0
if no of BBM flag is set and page parameter is 0. After that modification
way of discovering factory bad blocks will work similar as in kernel
version 5.1.
