From: Derek Foreman <der...@osg.samsung.com>
The boot partition currently has a size of 20 MiB but just the start elf
binaries account almost 12 MiB, which means that only 8 MiB is left for
the kernel image. A recent kernel with many of its options built-in can
easily be more than 4 MiB so let's double the boot partition size to 40
MiB to make sure that it has enough room for the kernel image, the DTBs
and possible even a backup kernel.
