[edk2-devel] [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.
