In the cpuid helper functions eax is always written to
by the cpuid instruction, so add it to the output clobbered list.
This prevents GCC from generating code with undefined behaviour
when the function is inlined.
Test: Verified that the generated assembly is sane and runtime
tests showed no "strange" behaviour when calling cpuid
functions.

Currently, all the masters controlled by DAPC are in domain 0. With
this setting, there is a potential security problem. For example, if a
certain master is somehow hacked, it may attempt to access registers
that it is not supposed to, with successful results. This is due to the
fact that, in the current setting, all masters are in domain 0 and can
access almost all registers. To prevent this problem, we assign masters
to different domains and restrict access to registers based on each
domain.
This patch sets domains for masters:
SSPM - domain 3
CPUEB - domain 14
PCIE0 - domain 2
SPM - domain 9

ASPM on the WLAN PCIe bus introduces large latency spikes, which can be
measured with cyclictest:
$ cyclictest --policy=rr --priority=12 --interval=10000 --threads=1 --loops=6000
Disabling ASPM for WLAN reduces the latency spikes from 2,500-3,000 usec
down to 35-65 usec. These latency spikes can impact the user when
real-time processes like Audio (cras) are starved of CPU time, leading
to buffer underruns resulting in crackling/distorted audio.
ASPM is already disabled for Nipperkin devices (CB:63537), so this CL
disables it for both in the shared declaration of
guybrush_czn_dxio_descriptors.

PSR data is created and stored in CSE data partition. In platforms that
employ CSE Lite SKU firmware, a firmware downgrade involves clearing of
CSE data partition which results in PSR data being lost. The PSR data
needs to be preserved across the firmware downgrade flow. CSE Lite SKU
firmware supports command to backup PSR data, and this command can be
sent only in post-RAM stages. So the cse_fw_sync actions needs to be
moved to ramstage.
This patch ensures SOC_INTEL_CSE_LITE_SYNC_IN_RAMSTAGE is selected when
PSR is enabled.

GPE is used on the Librem 11 for the keyboard dock connector, its sense

The register offsets are documented in the datasheet volume 2 (Intel

This adds support for booting the Librem L1UM v2 mainboard with
coreboot, using binaries from the original BIOS.
The following features have been tested on PureOS:
- USB: front USB3, rear USB3, USB2 header on board
- SATA: 8x SATA ports, one M.2 M-key shared with SATA0
- PCIe: two PEG slots, one PCIe slot from PCH, and one M.2 M-key
- Network: 2x GbE
- Video: BMC VGA and IPMI
- Serial: Physical serial port, provided by BMC SuperIO
- Hardware monitor
- POST code display
- TPM2
These binaries are extracted from the original BIOS:
- Intel Management Engine
- Intel Firmware Descriptor
This was developed and tested on a Librem L1UM v2 using a Core i7-9700
CPU. Native graphics init works for the Aspeed AST2500 BMC.
For development, the serial port console works from bootblock. Early
init waits for the BMC to finish booting since this is required for
serial port output.
