Author: marcel Date: Wed Apr 11 02:42:01 2012 New Revision: 234118 URL: http://svn.freebsd.org/changeset/base/234118 Log: uart_cpu_amd64.c and uart_cpu_i386.c (under sys/dev/uart) are identical now that the bus spaces are unified under sys/x86. Replace them with a single uart_cpu_x86.c. o delete uart_cpu_i386.c o move uart_cpu_amd64.c to uart_cpu_x86.c o update files.amd64 and files.i386 accordingly.
