2010-01-18 Robert Millan <rmh.grub@aybabtu.com>
Fix parallel builds.
* conf/common.rmk (font/font.c_DEPENDENCIES): New variable (makes
font.c depend on ascii.h).
2010-01-12 Carles Pina i Estany <carles@pina.cat>
* Makefile.in (DUSE_ASCII_FAILBACK): New macro.
2010-01-11 Carles Pina i Estany <carles@pina.cat>
* font/font.c (GENERATE_ASCII): Change the name to USE_ASCII_FAILBACK.
By default: disabled.
* Makefile.in (ascii.h): Remove the non-needed grub/bin2h size
parameter.
2010-01-10 Carles Pina i Estany <carles@pina.cat>
* font/font.c: Update copyright years.
* util/grub-mkfont.c (write_font_ascii_bitmap): Change comment format.
2010-01-10 Carles Pina i Estany <carles@pina.cat>
* font/font.c: Include `ascii.h'.
(ASCII_BITMAP_SIZE): New macro.
(ascii_font_glyph): Define.
(ascii_glyph_lookup): New function.
(grub_font_get_string_width): Change comment. If glyph not found, use
ascii_glyph_lookup.
(grub_font_get_glyph_with_fallback): If glyph not available returns
ascii_glyph_lookup.
* util/grub-mkfont.c (file_formats): New enum.
(options): Add `ascii-bitmaps' new option.
(usage): Add `asii-bitmaps' new option.
(write_font_ascii_bitmap): New function.
(write_font): Rename to ...
(write_font_p2): ... this. Remove print_glyphs call.
(main): Use file_format. Implement code for ranges if ascii-bitmaps is
used. Call print_glyphs.
* Makefile.in (pkgdata_DATA): Add `ascii.h'.
2010-01-14 Robert Millan <rmh.grub@aybabtu.com>
* conf/common.rmk (bin_UTILITIES): Add `grub-bin2h'.
(grub_bin2h_SOURCES): New variable.
* util/bin2h.c: New file.
2010-01-20 Vladimir Serbinenko <phcoder@gmail.com>
* include/multiboot.h: Resynced with spec.
