From: Greg Kurz <gkurz@linux.vnet.ibm.com>
Accesses to vring_avail_event and vring_used_event must honor the queue
endianness.
This patch allows cross-endian setups to use dataplane (tested with ppc64
on ppc64le, and vice-versa).

This reverts commit f5a5628cf0b65b223fa0c9031714578dfac4cf04.
This was an old patch that had been already superseded by b0e5d90eb
("dataplane: endianness-aware accesses").

MIPS doesn't need it, and including it creates problem as we are adding
dependency on ISA LPC bridge.

From: Paulo Alcantara <pcacjr@gmail.com>
This interface provides some registers within a 32-byte range and can be
acessed through PCI-to-LPC bridge interface (PMBASE + 0x60).
It's commonly used as a watchdog timer to detect system lockups through
SMIs that are generated -- if TCO_EN bit is set -- on every timeout. If
NO_REBOOT bit is not set in GCS (General Control and Status register),
the system will be resetted upon second timeout if TCO_RLD register
wasn't previously written to prevent timeout.
This patch adds support to TCO watchdog logic and few other features
like mapping NMIs to SMIs (NMI2SMI_EN bit), system intruder detection,
etc. are not implemented yet.

From: Paulo Alcantara <pcacjr@gmail.com>
This patch adds a testcase that covers the following:
1) TCO default values
2) first and second TCO timeout
3) watch and validate ticks counter through TCO_RLD register
4) maximum supported TCO timeout (0x3ff)
5) watchdog actions (pause/reset/shutdown/none) upon second TCO
timeout
6) set and get of TCO control and status bits

To: qemu-devel; +Cc: Paulo Alcantara, Peter Maydell, Paulo Alcantara, Igor Mammedov
From: Paulo Alcantara <pcacjr@gmail.com>
If the signal is sampled high, this indicates that the system is
strapped to the "No Reboot" mode (ICH9 will disable the TCO Timer system
reboot feature). The status of this strap is readable via the NO_REBOOT
bit (CC: offset 0x3410:bit 5).
The NO_REBOOT bit is set when SPKR pin on ICH9 is sampled high. This bit
may be set or cleared by software if the strap is sampled low but may
not override the strap when it indicates "No Reboot".
This patch implements the logic where hardware has ability to set SPKR
pin through a property named "noreboot" and it's sampled high by
default.

Extract the pc_cmos_init_floppy() function from pc_cmos_init(). The
function sets two RTC registers: floppy drive types (0x10), overwriting
the earlier value in there), and REG_EQUIPMENT_BYTE (0x14), setting bits
in the prior value.

From: Laszlo Ersek <lersek@redhat.com>
With the pc-q35-2.4 machine type, if the user creates an ISA FDC manually:
-device isa-fdc,driveA=drive-fdc0-0-0 \
-drive file=...,if=none,id=drive-fdc0-0-0,format=raw
then the board-default FDC will be skipped, and only the explicitly
requested FDC will exist. qtree-wise, this is correct; however such an FDC
is currently not registered in the CMOS, because that code is only reached
for the board-default FDC.
The pc_cmos_init_late() one-shot reset handler -- one-shot because the
CMOS is not reprogrammed during warm reset -- should search for any ISA
FDC devices, created implicitly (by board code) or explicitly, and set the
CMOS accordingly to the ISA FDC(s) with iobase=0x3f0:
- if there is no such FDC, report both drives absent,
- if there is exactly one such FDC, report its drives in the CMOS,
- if there are more than one such FDCs, then pick one (it is not specified
which one), and print a warning about the ambiguity.

Thanks to the last patch, pc_cmos_init() doesn't need the (optional)
board-default FDC any longer as an input parameter. Update
pc_basic_device_init() not to hand it back to pc_init1() / pc_q35_init(),
and update the latter not to carry the FDC to pc_cmos_init(). This
simplifies the code.

It seems to make sense to import pci_regs.h from linux:
why maintain our own?
As a first step, move the header to standard-headers,
and add it to the update script.
