Those boards are unable to map more than 512 kB of flash at a time. The
contents of bigger flash chips have to be retrieved with programmed I/O
in 3-byte chunks. If the LZMA code assumes the ability to unpack a
mapped image, it will fail. You need the stream decompressor variant of
lzma to get it working. Not sure if that variant is available in the
tree and working.
