The sd_bootpart_offset() function calculates the *runtime* offset which
changes as the guest switches between accessing the main user data area
and the boot partitions by writing to the EXT_CSD_PART_CONFIG_ACC_MASK
bits, so it shouldn't be used to calculate the main user data area size.

Instead, subtract the boot_part_size directly (twice, as there are two
identical boot partitions defined by the eMMC spec).

Should I pick this up for stable-9.1 branch?

yes.

Thanks,
