core/flash: Validate secure boot content size
[ Upstream commit e2018d2a3d46491dc2abd758c67c1937910b3a67 ]
Currently we don't check if the secure boot payload size fits within
the partition that we are reading it from. This results in strange
failures later on in boot if we cross the boundary between an ECCed
and a non-ECCed partition since libflash does not support reading
from regions with mixed ECC status.
Without this patch:
blocklevel_read: Can't cope with partial ecc
FLASH: failed to read content size 15728640 BOOTKERNEL partition, rc 3
With:
FLASH: Cannot load BOOTKERNEL. Content is larger than the partition
