(Take #2) If .bss wasn't large enough, and .ncdata was empty, .ncbss would be at an address overlapping the alignment-padded end of .ncdata and and linking would fail with an overlap error. Adds plugin load end address that accounts for IRAM going past the final .bss sections, making IRAM overlay compatible. load_code could also use this instead of the file size. The .lds becomes a bit more straightforward and explicit when assigning addresses. Change-Id: Id0c33f257710e97ece2c831e0feaaa32c1a14e05
