 What does 'Binaries blob' mean?

 The processor is called "i.MX53", I believe.  We also usually don't 
include the vendor name in the processor identification.  So something
like configs/imx53loco_defconfig is probably more appropriate.  OTOH,
Freescale themselves seem to call i.MX3x processors "imx" and i.MX5x
processors "mx5"...

 Personally I'd prefer to use a kernel defconfig (mx5_defconfig), but
perhaps this one is more appropriate.

 I think it is better (more predictable) to specify an exact version instead
of the latest HEAD.  Either a git sha or a tarball, e.g. 
http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/snapshot/rel_imx_2.6.38_12.01.01.tar.gz
(if that is a relevant snapshot at all).
