This commit performs below to create Bootblock binary. 1. createxbl.py: Converts "bootblock.raw.elf" to MBN (v7 format). 2. create_multielf.py: Concatenates TME SEQ, TME FW, QC_SEC and bootblock into multi ELF binary. BUG=b:415949107 TEST=Generate image.serial.bin and verify bootup on X1P42100 Change-Id: Icc499221d8806b549f6c873a14382a28c3efb74f Signed-off-by: Sasirekaa Madhesu <smadhesu@qualcomm.corp-partner.google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/88241 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Pranava Y N <pranavayn@google.com> Reviewed-by: Subrata Banik <subratabanik@google.com> Reviewed-by: Kapil Porwal <kapilporwal@google.com>
