MIPS: PowerTV: Simplify command line handling and needed config changes
Additional changes to Youichi Yuasa's command line simplication code The PowerTV platform uses a non-standard way to get the kernel command line--we insert a built-in command line into arcs_cmdline and to get additional command line information from the bootloader via a pointer in the a1 register. It is necessary to insert a space between to the two strings or the last argument from arcs_cmdline and the first argument from the bootloader may be inadvertantly combined. It is also necessary to set CONFIG_CMDLINE_BOOL to "y" and to set the default command line to an empty string to get the simplified code to work properly in the PowerTV environment.
