Ok, makes sense.

I also needed this one though:

diff --git a/drivers/thunderbolt/Kconfig b/drivers/thunderbolt/Kconfig
index bb0318ceaf93..de5d27ec67d6 100644
--- a/drivers/thunderbolt/Kconfig
+++ b/drivers/thunderbolt/Kconfig
@@ -1,7 +1,7 @@
 menuconfig THUNDERBOLT
 	tristate "Thunderbolt support for Apple devices"
 	depends on PCI
-	select APPLE_PROPERTIES if EFI_STUB
+	select APPLE_PROPERTIES if EFI_STUB && X86
 	select CRC32
 	help
 	  Cactus Ridge Thunderbolt Controller driver


Without that change, building on ARM with EFI_STUB enabled still
gives me a build failure.
