[PATCH edk2-platforms 0/5] SynQuacer SPI/TPM support

[Ard Biesheuvel]

This is the first part of a set of changes to support the Secure96
TPM on SynQuacer. This part only concerns usage by the OS of the TPM,
i.e., exposing the SPI controller and TPM peripherals correctly via
DT and ACPI.

Wiring up the TPM into UEFI requires more intrusive changes, and this
is a work in progress.

Note that patch #5 is only included for reference - it adds AML code
to reset the TPM when the device is probed via ACPI. This is necessary
since the firmware does not touch the TPM at all.

Ard Biesheuvel (5):
  Silicon/SynQuacer: add missing SPI controller interrupt lines to DT
  Silicon/SynQuacer: add ACPI description of second SPI controller
  Platform/Secure96Dxe: redefine LS connector CS as platform property
  Platform/Secure96Dxe: add TPM description to SSDT
  DO NOT MERGE - temporary hack to reset the TPM at probe time

[PATCH edk2-platforms 1/5] Silicon/SynQuacer: add missing SPI controller interrupt lines to DT

[Ard Biesheuvel]

Update the DT description of the second SPI controller with the TX,
RX and fault interrupt lines as they are assigned on SynQuacer.

[PATCH edk2-platforms 2/5] Silicon/SynQuacer: add ACPI description of second SPI controller

[Ard Biesheuvel]

The primary SPI controller on SynQuacer is reserved for the NOR
flash, and is not exposed to the OS. The second SPI controller is
wired to the low speed 96boards connector on DeveloperBox, and so
in order to use it, we must describe it to the OS (like we already
do in the device tree). So add the description to the DSDT as well.

[PATCH edk2-platforms 3/5] Platform/Secure96Dxe: redefine LS connector CS as platform property

[Ard Biesheuvel]

As opposed to the Secure96's I2C peripherals, whose bus addresses are
properties of the peripherals themselves, the SPI CS address of the
TPM is a property of the platform that incorporates the LS connector.

So tweak the macros that emit the CS values and related properties
to put it under the control of the platform that incorporates the
driver.

Urgh. We badly need to properly add some official macros for this.
You could possibly use __CONCATENATE from Base.h.

For new macros, we really should avoid leading _.
