Subject: [PATCH 1/3] avr32: remove .note.gnu.build-id section when making vmlinux.bin
This patch will remove the section .note.gnu.build-id added in binutils
2.18 from the vmlinux.bin binary. Not removing this section results in a
huge multiple gigabyte binary and likewize large uImage.

Subject: [PATCH 3/3] atmel_mpopfb: add signal to disable line caching and set correct output
This patch adds a signal to disable line caching, due to an errata in
silicon revision A. It also sets the output from MPOP to BGR to match
big endian framebuffer memory.
