The linux kernel relies on the RTC reporting pending interrupts if
the RTC alarm was used to wake the system. If we clear these flags
here then the rtc-cmos driver in the kernel will think that no
interrupts are pending and will not re-start the timerqueue to
handle the alarm timerqueue node.
This flag doesn't exist in SMM but the rtc code is compiled there.
Since rtc_init() is not called by SMM it is guarded with an ifdef.
I performed several thousand suspend/resume cycles without seeing
an issue where hwclock was unable to read from /dev/rtc. There
still is a potential kernel issue where the timerqueue can stall
but this makes that much less likely to happen on resume.

What happens is that the addresses read from various table headers'

passed to get_phys_mem, the crash happens while that function is
executed.
dlaurie@ found out that replacing "@" with "<" in fact fixes the

it will now create an 8M image with CBFS covering the last 1M of

Our linker script for romstage checks for global variables and
makes the build fail if there are any (on non-AMD systems).
This is great, but having the build fail without any indication
which variables are global is not very useful.
Moving the check to the Makefile allows us to let the linking stage
succeed and reveil which variable names end up in the data and bss
sections of the binary.
To test, add "int foo;" as the first line in src/mainboard/samsung/lumpy/romstage.c
and build coreboot for Lumpy. See the build break the following
way:
LINK cbfs/fallback/romstage_null.debug
Forbidden global variables in romstage:
00006a84 B foo

PCIE devices are detected and initialized by the AMD PCIe init functions,
which is in cimx rd890. The parameters are read from devicetree.cb before PCIe init.
Now, all bridges and devices are trained on the device 0.0 enable.
After PCIe init, the PCIe ports with devices are on and the PCIe ports
without devices are off. so resources may be allocated correctly
during the rest of the PCI scan.
But if the devicetree was being used to enable/disable devices after initialization,
the problems would arise. Take a look at the serial log:
do_pci_scan_bridge for PCI: 00:02.0
PCI: pci_scan_bus for bus 01
PCI: pci_scan_bus returning with max=001
do_pci_scan_bridge returns max 1
do_pci_scan_bridge for PCI: 00:03.0
PCI: pci_scan_bus for bus 02
PCI: pci_scan_bus returning with max=002
do_pci_scan_bridge returns max 2
do_pci_scan_bridge for PCI: 00:04.0
PCI: pci_scan_bus for bus 03
PCI: pci_scan_bus returning with max=003
do_pci_scan_bridge returns max 3
PCI bridge 02.0, 03.0 and 04.0 are not inserted devices, but these bridges
are still scanned. This is not correct.

There are four mainboards using agesa family15 code:
Supermicro h8scm and h8qgi, Tyan s8226 and AMD dinar.
All of these boards' PCI domain starts from 0x18.0. Take h8scm as
an example, PCI devices from 0.0 to 0x14.5 is under 0x18.0.
Now, the PCI domain's scan bus function stats from 0.0. This would
result to the PCI devices be scanned twice. Because when the function
run to device 18.0, it would scan from 0.0 again.
This issue would result to 2 problems:
1) PCI device may be assigned two different PCI address.
If this happenned on VGA device, coreboot maybe not load
vga bios correctly.
2) coreboot initializes rd890's IO APIC twice.
So this patch scans from 0x18.0 and could resolve the problems above.

As the field is for debug print use only, a minor change in the output
should do no harm. The strings no longer include word "Mainboard".

This is the smallest possible change to make early_serial.c
compile when included from romstage.c.
early_serial could be reworked to be built as separate unit
(romstage-y), but that should be done for all SuperIOs,
not some individual outlier.

The constant field "name" in chip_operations is common to multiple
different devices within a chip and cannot reflect the actual device
as found on the platform.
The intention is that a driver sets dev->name as part of the device
enumeration sequence with the detected hardware type and revision.
The field is for debug print use only.
