Hi,
this is a new submission of the Simon's work to add a way to boot Linux directly from the SPL. From the last patchset series, the main changes introduced by me are the following:
- compile the cache functions in SPL to make cleanup_before_linux() available. - do not call I"C function on boards where I2C is not available - fix a bug from last version (fallback to U-Boot) - move all related SPL stuff to common/ and fix omap related functions.
Tested on the twister board (patches for this board in u-boot-ti, next)
Note: to test it is also required Simon's patch:
