+
+FIRST... See the dedication in the decompress_bunzip2.c file as it applies
+here too. Donations to hospice in Toni's memory would be appreciated.
+
+As far as the code goes... the bzImage is just a bzip'd kernel image with
+a small gzip'd decompressor/loader stuck on front. CFE ungzip's the loader
+app which then relocates the bunzip decompressor into higher memory and
+bunzip's the compressed kernel directly from flash. Then the instruction
+cache is flushed (to remove traces of the loader) and the kernel is executed.
+
+Of course, a better approach would be to add bunzip decompression to CFE.
+
+Notes...
+ 1) Instruction cache size and linesize are hardcoded (see the #warning).
+ 2) Currently assumes at least 16M or ram.
+ 3) Thanks to Mike Baker mbm at alt dot org for bouncing ideas back
+ and forth as well as diagnosing the last (icache) bug.
