Update for latest versions and latest supported machines

Hi Enrico and Javier,

The idea of these updates is to track current mainline development with latest stable u-boot and linux recipes. After this I want to test what's is exactly working and what not, and focus our efforts to fix these problems in next mainline release.

Note that I use a personal repository from my github account for u-boot and kernel, this is to maintain a stable release until next mailine version is not released. If anyone want include  some new features (example the ISP feature) or fix something just need to send to me the patches and I'll include.

When a new mainline version is released, I'll port all the missing features still not included in the new release and we'll release the new version.

Some notes:
  I switched to use the hard floating point compiler.
  Reorganized the machine names, a machine name for every IGEP Processor and a common part.

Waiting for your comments,
