So on platforms with SAVE_PREV_BL_INITRAMFS_START_ADDR /
SAVE_PREV_BL_FDT_ADDR we have this same logic, but in C, and it's
working and fine, given what we do. So could we not follow the example
of arch/arm/lib/save_prev_bl_data.c and have
arch/arm/lib/bloblist.c and have just one implementation for arm32/64?
