Title:
  flash-kernel should support compressed kernels

Status in flash-kernel package in Ubuntu:
  Triaged
Status in flash-kernel package in Debian:
  Unknown

Bug description:
  When building an upstream kernel using "make deb-pkg" and not any of
  the Ubuntu-specific kernel build methods (such as debian/rules binary-
  headers binary-generic), the resulting linux-image deb package
  includes a gzip-compressed kernel image (copied from Image.gz, not
  Image). When such a deb package is installed on an arm64 system (such
  as McDivitt) and flash-kernel is run, it always calls "mkimage" with
  "-C none", which results in a uImage that can't boot.

  The attached patch adds a check to the mkimage_kernel() function in
  /usr/share/flash-kernel/functions to determine whether the kernel
  image is gzip-compressed or not, and calls "mkimage" with the
  appropriate "-C gzip" or "-C none" option. I have tested this patch on
  McDivitt, with both standard Ubuntu 3.13.0-37 and upstream 3.18-rc1
  kernels, and it works for me.
