grub/gentpl.py
Vladimir 'phcoder' Serbinenko a07a81b335 CMOS support on sparc. 
* gentpl.py (cmos): Add powerpc and sparc.
	* grub-core/Makefile.core.def (datetime): Add lib/ieee1275/cmos.c on
	powerpc and sparc.
	* grub-core/lib/cmos_datetime.c (grub_get_datetime)
	[__powerpc__ || __sparc__]: Rename to grub_get_datetime_cmos.
	(grub_set_datetime) [__powerpc__ || __sparc__]: Likewise to
	grub_set_datetime_cmos.
	* grub-core/lib/ieee1275/cmos.c: New file.
	* grub-core/lib/ieee1275/datetime.c (no_ieee1275_rtc): New vaiable.
	(find_rtc): Set no_ieee1275_rtc on error.
	(grub_get_datetime): Call grub_get_datetime_cmos on error.
	(grub_set_datetime): Call grub_set_datetime_cmos on error.
	* include/grub/cmos.h (grub_cmos_read): Return grub_err_t since it may
	fail. Move value to argument. All users updated
	(grub_cmos_write): Likewise.
	(grub_cmos_read) [__powerpc__ || __sparc__]: Rewritten.
	(grub_cmos_write) [__powerpc__ || __sparc__]: Likewise.
	* include/grub/datetime.h [__powerpc__ || __sparc__]: Declare
	grub_get_datetime_cmos and grub_set_datetime_cmos.
