If POST is rerun, try to do a machine reboot.
Add int 0x1589 support.
Review changes committed to coreboot, virtualbox, qemu, kvm, and bochs
cvs tip.
* bochs cvs (20091017):
-- 32bit pcibios, int1589
* coreboot (r3348): (bochs 20060708)
-- no noteworthy enhancements
* qemu (da5ff65d): (bochs 20090210)
-- changes synched
* kvm (e5c31442): (bochs 20090210)
-- tpr patching, 16MB rom, acpi-ssdt.dsl, 4K aligned pci mem
* virtualbox (r13560): (bochs 20061231)
-- lots of mouse changes, logo, scsi/etherboot hooks, int 1589,
floppy data rate?, int19 calls post
Possibly move code from entry_post in romlayout.S to C code in
handle_resume and always call 16bit C code on post.
Audit all sti/cli calls. Audit all call16 calls to make sure flags is
setup properly with respect to irqs.
The __call16 code does a long jump to the interrupt trampolines - this
is unnecessary.
Support PCIv3 roms? Add support for PCI "configuration code"
extensions?
Possibly add option to eliminate tsc based delays on emulators.
Add a kconfig style configuration program instead of requiring users
to modify config.h.
Support usb booting? Support usb mice?
Add a graphical boot splash screen?
Possibly support sending debug information over EHCI debug port.
