[PATCH 0/7] filetype: Some size reduction patches

[Sascha Hauer]

The am335x_mlo_defconfig is very size constrained and doesn't build
within these constraint anymore for some time. The filetype detection
code has become quite big and offers some opportunities for size
reduction. Specifically file_detect_type() is quite big, but many
callers are only interested in some specific file types like supported
file systems or supported compressed binary formats. This series
introduces some more specific smaller file detection functions so that
we can get rid of the big file_detect_type() in the binary.

Also included some patches for the myirtech-mid board to use a stripped
down device tree for the MLO. The same is already done for the other
boards supported in am335x_mlo_defconfig
