Together they make up piggy.img. + +The decompressor is built into the file decompress.o. It is turned into +the binary file decompress.bin, which is catted together with piggy.img +into the file vmlinuz. It can be executed in an arbitrary place in flash. + +Be careful - it assumes some things about free locations in DRAM. It +assumes the DRAM starts at 0x40000000 and that it is at least 8 MB, +so it puts its code at 0x40700000, and initial stack at 0x40800000. + +-Bjorn -- cgit v1.2.3-70-g09d2
