There was some disagreement about the usage of access_32b vs uap->port.iotype for determining whether we need 32-bit accessors or not.There was? I missed that, please send follow-on patches to resolve the issue if there is one.I can submit a patch that provides an alternative implementation, but I'm pretty sure Russell won't like it. For reference: http://www.spinics.net/lists/linux-serial/msg19710.html Russell said that UPIO_MEM is supposed to be literally only 8-bit access, but then Peter Hurley posted this: http://www.spinics.net/lists/linux-serial/msg19930.html which you applied. So my patch would remove access_32b and use UPIO_MEM32/UPIO_MEM instead. It would be a little weird having both patches in your tree, I guess.
I think it'll be ok if you just send a patch to use UPIO_MEM32 instead; I think that situation mostly had to do with inertia and not wanting to rebase a series like that (which I can appreciate). The worst that happens is Russell objects, but I think there's a good case for the simpler UPIO_MEM32 usage, which plays nice with earlycon. Regards, Peter Hurley
