Add a Kconfig option to select no specific platform support.
Signed-off-by: Stefano Stabellini <[email protected]>
---
Changes in v3:
- need to add ifneq ($(CONFIG_NO_PLAT),y) around subdir-y += platforms
otherwise compilation fails when no platforms are selected:
make -f /local/repos/xen-upstream/xen/Rules.mk -C
/local/repos/xen-upstream/xen/arch/arm built_in.o
make[3]: Entering directory `/local/repos/xen-upstream/xen/arch/arm'
make[3]: *** No rule to make target `platforms/built-in.o', needed by
`built_in.o'. Stop.
