2013-11-06	powerpc/scom: Enable 64-bit addresses	Benjamin Herrenschmidt	1	-4/+4
	On P8, XSCOM addresses has a special "indirect" form that requires more than 32-bits, so let's use u64 everywhere in the code instead of u32. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2013-10-11	powerpc/scom: Change scom_read() and scom_write() to return errors	Benjamin Herrenschmidt	1	-6/+17
	scom_read() now returns the read value via a pointer argument and both functions return an int error code Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2011-04-20	powerpc: Add SCOM infrastructure	Benjamin Herrenschmidt	1	-0/+156
	SCOM is a side-band configuration bus implemented on some processors. This code provides a way for code to map and operate on devices via SCOM, while the details of how that is implemented is left up to a SCOM "controller" in the platform code.
