Re: [PATCH] IntelFsp2Pkg: add TempRamExitPpi.h.

["Nate DeSimone" <nathaniel.l.desimone@intel.com>]

Hi Chasel,

Please update the comments for the TempRamExit() function declaration to include all of the FSP specification allowed return values:

EFI_SUCCESS - FSP execution environment was initialized successfully.
EFI_INVALID_PARAMETER - Input parameters are invalid.
EFI_UNSUPPORTED - The FSP calling conditions were not met.
EFI_DEVICE_ERROR - Temporary memory exit failed.

With this change...
