2011-07-05 Vladimir Serbinenko <phcoder@gmail.com>
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.
2011-07-02 Grégoire Sutre <gregoire.sutre@gmail.com>
* util/grub-mkconfig.in: Use @PACKAGE@ instead of hardcoded name when
sourcing grub-mkconfig_lib.
* util/update-grub_lib.in: Likewise.
* util/grub.d/00_header.in: Likewise.
* util/grub.d/10_hurd.in: Likewise.
* util/grub.d/10_kfreebsd.in: Likewise.
* util/grub.d/10_linux.in: Likewise.
* util/grub.d/10_netbsd.in: Likewise.
* util/grub.d/10_windows.in: Likewise.
* util/grub.d/20_linux_xen.in: Likewise.
* util/grub.d/30_os-prober.in: Likewise.
2011-06-28 Colin Watson <cjwatson@ubuntu.com>
* grub-core/term/gfxterm.c (grub_virtual_screen_setup): Use
default_bg_color rather than black.
(grub_gfxterm_fullscreen): Likewise.
(grub_gfxterm_background_color_cmd): Save new background color in
default_bg_color.
