7# Note: how the layout is done:
8#  we need to layout 2 segments, each contains sections:
9#    seg1: .data .dynamic
10#    seg2: .dynsym .dynstr .text .hash
11# for each segment, we start from the first section, regardless
12# whether it is an orphan or not (sections that are not listed in the
13# linkerscript are orphans):
14#   for seg1, we assign address: .data(0x4000), .dynamic(0x4008)
15#   for seg2, we assign address: .dynsym(0x2000), .dynstr(0x2018) ...
16# .dynsym is not an orphan, so we take address from script, we assign
17# .dynstr current address cursor, which is the end # of .dynsym and so
18# on for later sections.
19
20# Also note, it is absolutely *illegal* to have section addresses of
21# the same segment in none-increasing order, authors of linker scripts
22# must take responsibility to make sure this does not happen.
