VGA text support in qemu-mips
* grub-core/Makefile.core.def (kernel): Add term/i386/pc/vga_text.c,
term/i386/vga_common.c and kern/vga_init.c on qemu-mips.
* grub-core/kern/mips/qemu_mips/init.c (grub_machine_init): Init vga
text.
* grub-core/kern/i386/qemu/init.c: Renamed to ...
* grub-core/kern/vga_init.c: ... this.
* grub-core/kern/vga_init.c (VGA_ADDR) [__mips__]: Adjust.
(grub_qemu_init_cirrus) [__mips__]: Skip PCI and adjust the I/O base.
* grub-core/term/i386/pc/vga_text.c (VGA_TEXT_SCREEN) [__mips__]:
Adjust.
* include/grub/vga.h [GRUB_MACHINE_MIPS_QEMU_MIPS]: Declare
GRUB_MACHINE_PCI_IO_BASE.
2011-07-05 Vladimir Serbinenko <phcoder@gmail.com>
MIPS qemu flash support.
* grub-core/boot/mips/startup_raw.S [GRUB_MACHINE_MIPS_QEMU_MIPS]: Check
magic.
* grub-core/kern/mips/qemu_mips/init.c (probe_mem): New function.
(grub_machine_init): Probe memory if its size isn't known.
* util/grub-mkimage.c (image_targets): Add flash targets.
(generate_image): Handle flash targets.
2011-07-05 Vladimir Serbinenko <phcoder@gmail.com>
MIPS qemu at_keyboard support.
* gentpl.py (videoinkernel): Add qemu-mips.
* grub-core/Makefile.am (KERNEL_HEADER_FILES): Add necessary headers.
* grub-core/Makefile.core.def (kernel): Add at_keyboard and layout.
* grub-core/kern/mips/qemu_mips/init.c (grub_machine_init): Init new
modules.
* grub-core/term/at_keyboard.c (grub_keyboard_controller_init)
[GRUB_MACHINE_MIPS_QEMU_MIPS]: Don't consider original set.
* grub-core/term/serial.c (grub_serial_register)
[GRUB_MACHINE_MIPS_QEMU_MIPS]: Make com0 explicitly active.
