boot: Support "halt" in the boot order to prevent default boot attempts.
Current seabios will attempt to boot from both configured devices and

acpi: reintroduce LNKS
Commit 4540409 (acpi: LNKS is not needed, 2012-08-07) removed LNKS because
it basically worked by chance: _CRS returns something else then one of the
possible resources from _PRS, _DIS would not really disable the interrupt,
and there was no _SRS method. It just happened to work because all OSes
have some kind of special-casing for SCI.
Unfortunately, the code after the patch is also against the spec, and it
breaks FreeBSD because it treats IRQ 9 polarity as active low without
the Interrupt() entry. Actually, numeric _PRT entries are handled the
same in Linux and FreeBSD (as active-low). However, under Linux it just
happens to trigger another special casing of SCI which sets SCI up from
its override entry in the MADT, ignoring the DSDT completely.
This patch adds back the LNKS, but without using the PIIX register for
LNKA in its methods.

The build textually includes all the code together in one unit for the

There is a small change in the ASL: instead of including the number of

allow CPUs to have non-contiguous Local APIC IDs (v2)
Extract Local APIC IDs directly from the CPUs, and instead of check for
"i < CountCPUs", check if the APIC ID was present on boot, when building
ACPI tables and the MP-Table.
This keeps ACPI Processor ID == APIC ID, but allows the
hardware<->SeaBIOS interface be completely APIC-ID based and not depend
on any other kind of "CPU identifier". This way, SeaBIOS may change the
way ACPI Processor IDs are chosen in the future.
As currently SeaBIOS supports only xAPIC and not x2APIC, the list of
present-on-boot APIC IDs is a 256-bit bitmap. If one day SeaBIOS starts
to support x2APIC, the data structure used to enumerate the APIC IDs
will have to be changed (but this is an internal implementation detail,
not visible to the OS or on any hardware<=>SeaBIOS interface).
For current QEMU versions (that always make the APIC IDs contiguous),
the OS-visible behavior and resulting ACPI tables should be exactly the
same. This patch will simply allow QEMU to start setting non-contiguous
APIC IDs (that is a requirement for some sockets/cores/threads topology
settings).
Changes v1 -> v2:
- Use size suffixes on all asm instructions on smp.c
- New patch description
report real I/O APIC ID (0) on MADT and MP-table (v3)
When resetting an I/O APIC, its ID is set to 0, and SeaBIOS doesn't
change it, so report it correctly on the ACPI MADT table and MP-table.
Some hardware may require the BIOS to initialize I/O APIC ID to an
unique value, but SeaBIOS doesn't do that. This patch at least makes the
tables reflect reality.

- Fix MP-table too, not just ACPI MADT table
Changes v1 -> v2:
- Cosmetic: whitespace change (removed extra newline)

This patch adds support for the lsi53c895a scsi host adapter,

This driver was written by looking at the expectations of qemu's

real hardware, and I somehow doubt anyone cares given the age of
physical lsi scsi cards. It depends on !COREBOOT for that reason.
This patch adds support for booting from UAS (usb
attached scsi) devices.
For now only usb 2.0 support is there. On usb 3.0 the
UAS protocol uses streams, so changes will be required
to make usb 3.0 devices fly once we have a xhci host
controller driver.
So far the driver has been tested on qemu-emulated
virtual hardware only. In theory should just work on
bare metal too.
