Stefan Reinauer 03cafbfdfe Trivial (cosmetic) cleanup:
* Only open /dev/mem once and do it early.
* Drop extern for function prototypes.
* Minimize ts5300 impact in probe_flash()

This cleanup will making ICH7 SPI support quite some easier.

Luc Verhaegen b8c6437811 flashrom: split flash_enable.c into chipset_enable.c and board_enable.c
This splits up the ROM Write enable code into chipset specific and
board specific parts. This of course means that a lot of code is
plainly moved about.

* Allows for linuxbios name matching and pci-subsystem id matching.
  The latter uses a double set to properly distuinguish boards despite
  of some known vendors being lax about it.
* Fixes GPIO15 being raised on every VT8235 southbridge, regardless of what
  that line actually controls; rom on EPIA-M, backlight on mitac 8999 laptop.
* Adds flashrom support for Asus A7V400-MX (KM400 + VT8235)
* Island aruma was renamed agami aruma, the board specific code now got
  adjusted. A set of pci-ids was retrieved from source code.

Uwe Hermann 1a9c892d58 Initial Intel 440BX RAM initialization framework.
This does _not_ fully work, yet. You will _not_ be able to boot any
payload with this code, yet.

Add missing license headers.

Base the northbridge.c file on the Intel 855PM version, that comes
closer to what we want.

The raminit.c file is written from scratch and hardcodes several
values for now. This needs to be fixed later by reading the
correct values via SPD.

Roman Kononov 958a1f308a I have Sun Ultra40 workstation. Southbridge is nVidia CrushK8-04/nforce
2200 (too many names, sounds like a criminal).

1) Linuxbios loads kernel A; kernel A loads kernel B. Everything works
fine.

2) Then I push the reset button.

3) Linuxbios loads kernel A; kernel A loads kernel B. Kernel B complains
about wrong checksum of the mptable and crushes later.

An investigation showed that in 3), short after kernel A (v2.6.19.2)
sets
the Bus Master Enable bit of the nVidia's USB1 controller
(pci_set_master()),
the mptable gets two bytes at physical address 0x80 damaged.

Nothing is plugged to the USB ports. Other two Sun workstations had the
same
behavior. This does not make sense to me unless the controller has a HW
bug.

I believe, this should better be fixed in the kernel USB driver.

For now this patch offers a possibility for linuxbios to reset the USB
controller by setting HostControllerReset bit in HcCommandStatus
Register.
It is enablead by using 'register "usb1_hc_reset"="1"' in 'chip
southbridge/nvidia/ck804' section of the mainboard's Config.lb.

Ed Swierk c3aaf6a99e This patch adds the MCP55 PCI IDs (without which the southbridge code
won't compile), and breaks an unnecessary dependency on the usbdebug
code.

Roman Kononov 57e700f4f4 great check-in message:
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

    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

Kexec is happier with the patch.
