For those who are into the details: here is [1]a step-by-step guide through the process of decompressing an Arm kernel and getting ready to boot from Linus Walleij. " Next the decompression code sets up a page table, if it is possible to fit one over the whole uncompressed+compressed kernel image. The page table is not for virtual memory, but for enabling cache, which is then turned on. The decompression will for natural reasons be much faster if we can use cache. "
