# Note: how the layout is done:
#  we need to layout 2 segments, each contains sections:
#    seg1: .data .dynamic
#    seg2: .dynsym .dynstr .text .hash
# for each segment, we start from the first section, regardless
# whether it is an orphan or not (sections that are not listed in the
# linkerscript are orphans):
#   for seg1, we assign address: .data(0x4000), .dynamic(0x4008)
#   for seg2, we assign address: .dynsym(0x2000), .dynstr(0x2018) ...
# .dynsym is not an orphan, so we take address from script, we assign
# .dynstr current address cursor, which is the end # of .dynsym and so
# on for later sections.

# Also note, it is absolutely *illegal* to have section addresses of
# the same segment in none-increasing order, authors of linker scripts
# must take responsibility to make sure this does not happen.
