These files are modifications so android works on the kobo mini.
https://github.com/marek-g/kobo-kernel-2.6.35.3-marek arch/arm/mach-mx5/mx50_rdp.c The Kobo Mini uses a different port on the SoC for the internal uSDHC to other readers from in i.MX507 family... SD3
kobo u-boot-2009.08 sources include/configs/mx50_rdp.h The Android uses partition 2 instead of partition 1, other command line parameters have been added /mmcblk0p2 rootfstype=ext4 rootwait rw noinitrd init=/init video=mxc_elcdif_fbff
