commit d55f09d9bc3ff592ec90a046eb9ad0558813ef4b Author: Lee Leahy leroy.p.leahy@intel.com Date: Sun Jul 24 18:21:13 2016 -0700
drivers/intel/fsp2_0: Display FSP calls and status
Disable the chatty FSP behavior for normal builds. Use a Kconfig value to enable the display of the FSP call entry points, the call parameters and the returned status for MemoryInit, SiliconInit and FspNotify. Use inline functions to reduce the impact on the mainline code and compiled results.
TEST=Build and run on Galileo Gen2
