-/**
- Makes a SAL procedure call.
-
- This is a wrapper function to make a SAL procedure call.
- No parameter checking is performed on the 8 input parameters,
- but there are some common rules that the caller should follow
- when making a SAL call. Any address passed to SAL as buffers
- for return parameters must be 8-byte aligned. Unaligned
- addresses may cause undefined results. For those parameters
- defined as reserved or some fields defined as reserved must be
- zero filled or the invalid argument return value may be returned
- or undefined result may occur during the execution of the procedure.
- This function is only available on IPF.
-
- @param Index The SAL procedure Index number.
- @param Arg2 The 2nd parameter for SAL procedure calls.
- @param Arg3 The 3rd parameter for SAL procedure calls.
- @param Arg4 The 4th parameter for SAL procedure calls.
- @param Arg5 The 5th parameter for SAL procedure calls.
- @param Arg6 The 6th parameter for SAL procedure calls.
- @param Arg7 The 7th parameter for SAL procedure calls.
- @param Arg8 The 8th parameter for SAL procedure calls.
-
- @return SAL returned registers.

- The constructor function of UEFI SAL Lib.
-
- The constructor function looks up the SAL System Table in the EFI System Configuration
- Table. Once the SAL System Table is found, the SAL Entry Point in the SAL System Table
- will be derived and stored into a global variable for library usage.
- It will ASSERT() if the SAL System Table cannot be found or the data in the SAL System
- Table is not the valid data.
-
- @param ImageHandle The firmware allocated handle for the EFI image.
- @param SystemTable A pointer to the EFI System Table.
-
- @retval EFI_SUCCESS The constructor always returns EFI_SUCCESS.
