//  Values are 32 bit values layed out as follows:

//      Lev - is the Level code
//
//          00 - Success
//          01 - Informational
//          10 - Warning
//          11 - Error
//
//      C - is the Customer code flag  (must actually be set)
//
//      R - is a reserved bit    (unused)
//
//      Facility - is the facility code: TCPA: proposal 0x028
//
//      Code - is the facility's status code
//


// no macros are used below intentionally
// for a better error code recognition by the reader

// note that the values of TPM_E_BASE and TSS_E_BASE, TSS_W_BASE and TSS_I_BASE
// have to be adjusted for a platform other than Windows

//
// TPM specific error codes (layer nibble set to TPM layer TSS_LAYER_TPM)
