Dear Andrew Gabbasov,
Your patch seems to newly generate the following warning and error, because your patch is changing the type of 'qry->max_buf_write_size' from u16 to u8[2].
cfi_flash.c:2038:33: warning: comparison between pointer and integer [enabled by default] cfi_flash.c:2046:27: error: incompatible types when assigning to type 'u8[2]' from type 'int'
By the way, I also had this unalignment access problem for my board. Before finding your patch, I was thinking another way to fix this problem.
My idea is to just use 'get_unaligned' and 'put_unaligned' functions instead of introducing special macros. With this way, we don't need to change the fields of struct cfi_qry.
If you fix the above problem, I think your patch will be fine. But I am wondering which way is more smart.
Best regards, Masahiro Yamada
