# CM4 image starts right after the header and the CM4 image begins with the
# interrupt vector table. The starting address of the table must be 1024-bytes
# aligned. See README.md for details.
# Number of bytes to be aligned to = Number of interrupt vectors x 4 bytes.
# (1024 = 256 x 4)
# 
# Header size is used in two places. 
# 1. The location of CM4 image is offset by the header size from the ORIGIN
# value specified in the linker script. 
# 2. Passed to the imgtool while signing the image. The imgtool fills the space
# of this size with zeroes and then adds the actual header from the beginning of
# the image.
