The change in tables.c protects the legacy x86 BIOS data segment
(0x400-0x4ff) from being used for storing coreboot tables. Some
bytes from the segment are used by the kernel and should not be
garbled.
The change in coreboot_table.c is not strictly necessary. It removes
some redundancy and confusion.

This field is rarely used (and not used in the LX tables).
There is not a good reason to mask off non-exclusive IRQs.

You can see this by executing commands like this:
grep -r pci_assign_irqs coreboot/src/*
This basically AMD/LX based boards: pcengines/alix1c,
digitallogic/msm800sev, artecgroup/dbe61, amd/norwich, amd/db800.
Also for AMD/GX1 based boards need a patch
[http://www.pengutronix.de/software/ptxdist/temporary-src/references/geode-5530.patch]
for the right IRQ setup.
AMD/GX1 based boards is: advantech/pcm-5820, asi/mb_5blmp, axus/tc320,
bcom/winnet100, eaglelion/5bcm, iei/nova4899r, iei/juki-511p.
I have two ideas.
1. Delete duplicate code from AMD/LX based boards.
2. Add IRQ routing for AMD/GX1 boards in coreboot.
The pirq.patch for IRQ routing logically consist from of two parts:
First part of pirq.patch independent from type chipsets and assign IRQ for
ever PCI device. It part based on AMD/LX write_pirq_routing_table() function.
Second part of pirq.patch depends of type chipset and set PIRQx lines
in interrupt router. This part supports only CS5530/5536 interrupt routers.
IRQ routing functionality is included through PIRQ_ROUTE in Config.lb.
Tested on iei/juki-511p(cs5530a), iei/pcisa-lx(cs5536) and also on
TeleVideo TC7020, see

However this patch is not enough to enable it on Linux, Linux do not trust
BIOSes too much, so a small patch to kernel to disable the check if this
region is e820 reserved.

Linuxbios boots an Opteron motherboard with 1GB memory.
Linuxbios directly loads a recent linux kernel.
The memory layout is like this:
BIOS-provided physical RAM map:
BIOS-e820: 0000000000000000 - 0000000000000e18 (reserved)
BIOS-e820: 0000000000000e18 - 00000000000a0000 (usable)
BIOS-e820: 00000000000c0000 - 00000000000f0000 (usable)
BIOS-e820: 00000000000f0000 - 00000000000f0400 (reserved)
BIOS-e820: 00000000000f0400 - 0000000040000000 (usable)
The f0000-f0400 region contains IRQ and ACPI tables.
At some point the kernel builds a resource table containing
all physical address ranges and type of hardware the addresses
are mapped to. The table is accessible via /proc/iomem:
# cat /proc/iomem
00000000-00000e17 : reserved
00000e18-0009ffff : System RAM
000a0000-000bffff : Video RAM area
000c0000-000cbfff : Video ROM
000f0000-000fffff : System ROM
e0000000-efffffff : PCI Bus #03
e0000000-efffffff : 0000:03:00.0
f0000000-f3ffffff : GART
f4000000-f60fffff : PCI Bus #03
f4000000-f4ffffff : 0000:03:00.0
f5000000-f5ffffff : 0000:03:00.0
f6000000-f601ffff : 0000:03:00.0
f6100000-f6100fff : 0000:00:01.0
f6101000-f6101fff : 0000:00:02.0
f6101000-f6101fff : ohci_hcd
f6102000-f6102fff : 0000:00:04.0
f6103000-f6103fff : 0000:00:07.0
f6103000-f6103fff : sata_nv
f6104000-f6104fff : 0000:00:08.0
f6104000-f6104fff : sata_nv
f6105000-f6105fff : 0000:00:0a.0
f6106000-f61060ff : 0000:00:02.1
f6200000-f620ffff : 0000:40:01.0
As you can see, the 00000000000f0400-0000000040000000
region is not listed.
It is not listed because the kernel unconditionally adds
"000f0000-000fffff : System ROM" first (look for
"request_resource(&iomem_resource, &system_rom_resource)"),
and then the attempt to add f0400-40000000 range fails
because of overlapping.
The kernel does not care that the range is not listed there.
Kexec does. It uses the /proc/iomem file to instruct the
kexec system call how to place the segments of a new kernel
in the physical memory. Kexec fails to start a new kernel
because it cannot locate enough physical memory.
This must be fixed either in linux or linuxbios.
Assuming that linuxbios is to be fixed, I cooked a patch
which provides this memory layout:
BIOS-provided physical RAM map:
BIOS-e820: 0000000000000000 - 0000000000000e18 (reserved)
BIOS-e820: 0000000000000e18 - 00000000000a0000 (usable)
BIOS-e820: 00000000000c0000 - 00000000000f0000 (usable)
BIOS-e820: 00000000000f0000 - 0000000000100000 (reserved)
BIOS-e820: 0000000000100000 - 0000000040000000 (usable)
The /proc/iomem contains:
# cat /proc/iomem
00000000-00000e17 : reserved
00000e18-0009ffff : System RAM
000a0000-000bffff : Video RAM area
