Anyone building a linux kernel using buildroot (http://buildroot.uclibc.org/). will get my patches vs U-Boot 1.2.0. Since the U-Boot community insists that the tested working flash driver cannot be merged in the std U-boot, and has to be replaced by the CFI driver which does not work on the EK (I am told) I have no plans to resubmit at this time. > Best Regards, > J.
