Are those two incompatible? I would recommend starting without board
specific defconfig
files, it just gets messy once you get more than a few machines you
want to support.

You usually don't want to select 'CONFIG_EMBEDDED' for regular
builds, it's should only be needed to disable options that are
usually considered essential.

You have a framebuffer console here, but no framebuffer driver?

Maybe use EXT4, not EXT2, in the defconfig?
