If something like this was planned for BeagleBoard anyway, then perhaps it could written in terms of these TRY_MMC etc. macros (which seem like a reasonable idea to me). Then a working prototype could be posted as an RFC for others to comment on? I suspect at the moment there's not many people reading this 'vexpress' thread ;-) -- Tixy _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
