This is an extention of Daniel Schwierzeck's work [1] on a new SPL framework and is intented only as a prototype to facilitate further discussion.
Please refer [2] for an overview of this approach:
I have extended his work to make it a little more generic, did some minor modifications and adapted it for OMAP4 as a prototype.
Appreciate your feedback.

Aneesh V (3): armv7: adapt Makefile for spl building omap: common spl support for OMAP3/4 omap4: adapt Makefile for spl building
Daniel Schwierzeck (4): Adapt config.mk for usage in spl/Makefile Use ALL-y style instead of ifeq blocks for better readability and upgradeability Add new folder and build system for SPL Hook spl directory into main Makefile
