[ELDK] Benefit of ELDk

The very short summary is that Yocto focuses on a few spcific hardware
configurations; for example, ARM support uses the Beagleboard as
reference, so all testing will be done with an ARMv7a specific set of
options only.  If you need a configuration for a slightly different
architecture - say, ARMv6 - enter an untested area, and may easily
face more or less obvious problems.  The ELDK offers out-of-the box
solutions for a wider range of target architectures.

For a longer description of how Yocto and ELDK are related to each
other, and why things are as they are, please see the documentation at

A layer on top of Yocto yes,  but I would not call it a "BSP"
(Board Support Package), as the ELDK tries to _not_ be so board
specific as this is the case with Yocto; instead we try to support
whole families of target systems.

Hope this helps.

Best regards,

Wolfgang Denk
