So a decompressor is in ROM, reads from ROM, writes to RAM and has its
stack in cache? Or do we uncompress to cache?

How big is that cache? I can modify lzma to only need 6000 bytes stack
and no additional memory allocations.

Are reads from ROM special (alignment problems etc)? Can I treat stack
like normal RAM?
