        * config/bfin/t-bfin-elf (MULTILIB_OPTIONS, MULTILIB_DIRNAMES,
	MULTILIB_MATCHES, MULTILIB_EXCEPTIONS): Remove mcpu=bf532-0.3,
	mcpu=bf561-none and mcpu=bf561-0.2.
	* config/bfin/t-bfin-uclinux (MULTILIB_OPTIONS, MULTILIB_DIRNAMES,
	MULTILIB_MATCHES, MULTILIB_EXCEPTIONS): Likewise.
	* config/bfin/t-bfin-linux (MULTILIB_OPTIONS, MULTILIB_DIRNAMES,
	MULTILIB_MATCHES, MULTILIB_EXCEPTIONS): Likewise.
	* config/bfin/bfin-protos.h (enum bfin_cpu_type): Add
	BFIN_CPU_UNKNOWN.
	* config/bfin/elf.h (STARTFILE_SPEC): Use specific CRT for
	BF561.
	(LIB_SPEC): Use proper linker script for bf561.  Error if no mcpu
	option.
	* config/bfin/bfin.c (bfin_cpu_type): Set to BFIN_CPU_UNKNOWN.
	(cputype_selected): Remove.
	(bfin_handle_option): Don't use cputype_selected.
	(override_options): When no mcpu option, enable all workarounds.
	Don't use bfin_workarounds.
	* config/bfin/bfin.h (DRIVER_SELF_SPECS): Don't set default
	processor type.
	(DEFAULT_CPU_TYPE): Don't define.
