Subject: serial_mx31: allow it to work with mx27 too and rename to serial_mxc
X-Git-Tag: v2009.08-rc1~118^2~34
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=47d19da4d3f9ac4787abe9dee32406478424be52;p=platform%2Fkernel%2Fu-boot.git

serial_mx31: allow it to work with mx27 too and rename to serial_mxc

UART hardware on i.MX27 is the same as on the i.MX31 so we just
need to provide the driver with correct address of the registers.
