775ed87ac4 tools: zynqmpimage: Align image_size/image_stored_size
Bootrom is not capable to work with non aligned bootloader sizes.
SPL with OF_SEPARATE generates non-align images quite often that's
why this change is required before OF_SEPARATE enableding.

16c78cba92 tools: zynqmpimage: round up partition size
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.

6915dcf359 tools: zynqmpimage: Add bif support
The officially described way to generate boot.bin files for ZynqMP is to
describe the contents of the target binary using a file of the "bif"
format.  This file then links to other files that all get packed into a
bootable image.

This patch adds support to read such a .bif file and generate a respective
ZynqMP boot.bin file that can include the normal image and pmu files, but
also supports image partitions now. This makes it a handy replacement for
the proprietary "bootgen" utility that is currently used to generate
boot.bin files with FSBL.
