The ARM zImage is supposed to be self-extracting, right?
Is it possible to package that as an uncompressed code for
lzma-loader was created at the time when MIPS didn't have
zboot support. In ramips, the lzma-loader does the same
work as the kernel zboot image: It's a loader which extracts
the actual kernel code to the memory. The compressed kernel
is linked as a part of the lzma-loader so it doesn't need any
flash access.
