cpu/

	* frv.cpu (nsdiv, nudiv, nsdivi, nudivi): Remove fr400 profiling unit.
	(scutss): Change unit to I0.
	(calll, callil, ccalll): Add missing FR550-MAJOR and profile unit.
	(mqsaths): Fix FR400-MAJOR categorization.
	(media-quad-multiply-cross-acc, media-quad-cross-multiply-cross-acc)
	(media-quad-cross-multiply-acc): Change unit from MDUALACC to FMALL.
	* frv.opc (fr400_check_insn_major_constraints): Check for (M-2,M-1)
	combinations.

opcodes/
	* frv-desc.c, frv-opc.c: Regenerate.

sim/frv/
	* cache.c (frv_cache_init): Change fr400 cache statistics to match
	the fr405.
	(non_cache_access): Add missing breaks.
	* interrupts.c (set_exception_status_registers): Always set EAR15
	for data_access_errors.
	* memory.c (fr400_check_write_address): Remove redundant alignment
	check.
	* model.c: Regenerate.
