The FSBL copies "Total Partition Word Length" * 4 bytes from the boot.bin, which implies that the partition size is 4 byte aligned. When writing the partition, mkimage calculates "Total Partition Word Length" by dividing the size by 4. This implicitly cuts unaligned bytes at the end of the added binary.
Instead of rounding down, the size must be round up to 4 bytes and the binary padded accordingly.
