In a later patch, we'll modify the depex of
"ArmPkg/Drivers/CpuDxe/CpuDxe.inf" (currently "AFTER gArmGicDxeFileGuid")
to "gHardwareInterruptProtocolGuid OR gHardwareInterrupt2ProtocolGuid".
Considering platforms that include "ArmPkg/Drivers/CpuDxe/CpuDxe.inf",
there are two classes:
(1) The platform gets its gHardwareInterruptProtocolGuid or
gHardwareInterrupt2ProtocolGuid instance from
"ArmPkg/Drivers/ArmGic/ArmGicDxe.inf". For such platforms, the
upcoming CpuDxe change is not a problem, because commit 61a7b0ec63
made ArmGicDxe wait for the CPU Arch Protocol with a protocol notify.
(2) The platform gets its hardware interrupt protocol(s) from a different
driver that has a hard depex on the CPU Arch Protocol. The upcoming
CpuDxe change would lead to a loop in the DXE dispatch order.
In the edk2 tree, only "BeagleBoardPkg/BeagleBoardPkg.dsc" falls in class
(2), and the driver in question is "Omap35xxPkg/InterruptDxe". Port (most
of) commit 61a7b0ec63 to it.
