We had been concerned with the SPL case, and the current driver work-around is how we do it (as to not litter gd->arch with lots of things just for drivers we need so very very early in SPL). York now has a different setup where this i2c block is being reused, where SRAM is big enough (apparently) to load the whole of U-Boot into and start execution from, but we still want to relocate into DDR. This is a problem over in TI-land we've avoided by simply saying "lets keep using SPL anyhow". -- Tom -------------- next part -------------- A non-text attachment was scrubbed...
