X-Git-Tag: v2.6.39-rc1~456^2~17^3~15 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e735038f3848a720f84a819c8191ed2f6a1beed8;p=karo-tx-linux.git serial: sh-sci: Kill off unused membase kludge. All users of the platform port data specify a mapbase where the driver later derives the membase from. Now that UPF flags are taken in to account for generic ioremapping we can kill off the port-specific membase clobbering and simply use the generic paths. This derives from a time when sh64 was not capable of using the generic ioremap implementation and had employed early bolted DTLB mappings for port access, which is no longer an issue.
