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.
