[edk2-devel] [PATCH edk2-platforms v2 0/2] enable Secure96 mezzanine on ACPI systems

[Ard Biesheuvel]

This series plumbs in the support for describing 96boards mezzanines
via ACPI, and uses it to add a description of the Secure96. Note that
the TPM is still missing at the moment, but the I2C crypto accelerators
and the GPIO LEDs are covered.

Changes since v1:
- Don't rely on a ACPI device in the host platform's namespace to describe
  the GPIO lines - this prevents the mezzanine from using GPIOs as interrupts,
  and is generally far too restrictive. Since we need a hack (see below) for
  I2C anyway, just use the same method for the GPIO controller.
- I2C resources are described with a reference to the I2C controller via a
  string argument, which cannot be parameterized using PCDs like we do with
  GPIO interrupt numbers. (This is due to the fact that string PCDs are not
  expanded to true string literals by EDK2's AutoGen.h CPP magic). So add the
  default names (e.g., \_SB.I2C0) to Secure96.h, and permit a platform to
  override them if necessary by setting a scoped build option with a -D
  argument.

Ard Biesheuvel (2):
  Platform/96Boards: add ACPI support to mezzanine/LS connector driver
  Platform/Secure96Dxe: add ACPI description of the LEDs and I2C
    peripherals
