...when specified in the guest configuration file.
This work is somewhat based on Bei Guan effort during the SoC 2011 and
relies on upstream edk2/ovmf Tianocore ROM to be built separately and
manually copied as:
Build/OvmfX64/DEBUG_GCC44/FV/OVMF.fd ->
tools/firmware/ovmf/ovmf-x64.bin
Build/OvmfIa32/DEBUG_GCC44/FV/OVMF.fd ->
toolf/firmware/ovmf/ovmf-ia32.bin
A way to integrate OVMF build directly into XEN has still be discussed
on the mailing list appropriately.

This patch introduces configuration options allowing to built either a
rombios only or a seabios only hvmloader.
Building option ROMs like vgabios or etherboot is only enabled for a
rombios hvmloader, since SeaBIOS takes care or extracting option ROMs
itself from the PCI devices (these option ROMs are provided by the
device model and do not need to be built in hvmloader).
The Makefile in tools/firmware/ now only checks for bcc if rombios is
enabled.
These two configuration options are left on by default to remain
compatible.

The SeaBIOS integration here is only semi-complete and is targetted at
developers and very early adopters who can be expected to cope with
some rough edges. In particular the user must clone, patch as
necessary and compile SeaBIOS themselves since this patchset does not
cover any of that (in the same way we currently do not integrate
upstream qemu clone+build). Include a big comment to that effect next
to the Config.mk option.
Many of the bios_config callback functions are not yet used by
SeaBIOS.

Pass the table address as a paramter to the build function and cause
it to return the number of entries. Pass both base and offset as
parameters to the dump function.
This adds a duplicated e820.h header to ROMBIOS. Since the e820 data
structure is well defined by existing BIOS implementations I think
this is OK and simplifies the cross talk between hvmloader and
ROMBIOS.
Reduces the cross talk between ROMBIOS and hvmloader.

If you use -MMD -MF then the correct .o filename is written to the
.*.d file as the compiler driver arranges everything. This was done
in 19010:275abe1c5d24 for the hypervisor.
In this patch we do the same elsewhere in the xen-unstable tree,
particularly tools/. Specifically:
* Change tools/Rules.mk to add -MMD -MF ... to CFLAGS and set DEPS.
* Remove -Wp,-MD... from every other Makefile
* Remove setting of DEPS from every other Makefile
* Ensure that every Makefile says -include $(DEPS)
* Ensure that every Makefile's clean target removes $(DEPS)
Some Makefiles were already halfway there, but often for a different
variable name eg PROG_DEP. The variable name is now standardised in
Rules.mk as DEPS.
I have done a test build with this change, on Debian etch.

compiled with gcc and linked into the hvmloader as a byte-array.
Hvmloader allocates memory (rounded up to next 64kb) from the e820
table
below 4GB, copies and relocates the 32bit code in the allocated area
and
copies a jumptable (located in a section '.biosjumptable') pointing to
the 'exported' functions into the Bochs BIOS's memory area to link the
two code sections. The memory area has been reserved and can be
identified with the signature '___JMPT'.
In the Bochs BIOS only stub functions are provided. These load the
index
of a particular function in the jump table, switch to protected mode
and
call the function in the high memory area. The stack is prepared such
that functions compiled by gcc can just pick the parameters from the
stack as usual - this means that the 16bit real-mode return address is
taken off the stack. The stub functions should have the same signature
as those in 32bit space. For ABI compatibility reasons parameters
inside
the Bochs BIOS stubs should all be 32bit wide.
This patch includes a test function that calls three gcc-compiled
functions in the high memory area and displays their success status.
Simple tests are done doing multiplication and addition of 32-bit
numbers and reading and modification of a static variable. These
functions test the interface and the relocation code. The test code is
removed in patch part 3.
