4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Makes a SAL procedure call.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync This is a wrapper function to make a SAL procedure call.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync No parameter checking is performed on the 8 input parameters,
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync but there are some common rules that the caller should follow
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync when making a SAL call. Any address passed to SAL as buffers
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync for return parameters must be 8-byte aligned. Unaligned
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync addresses may cause undefined results. For those parameters
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync defined as reserved or some fields defined as reserved must be
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync zero filled or the invalid argument return value may be returned
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync or undefined result may occur during the execution of the procedure.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync This function is only available on IPF.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param Index The SAL procedure Index number.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param Arg2 The 2nd parameter for SAL procedure calls.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param Arg3 The 3rd parameter for SAL procedure calls.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param Arg4 The 4th parameter for SAL procedure calls.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param Arg5 The 5th parameter for SAL procedure calls.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param Arg6 The 6th parameter for SAL procedure calls.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param Arg7 The 7th parameter for SAL procedure calls.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param Arg8 The 8th parameter for SAL procedure calls.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @return SAL returned registers.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync // mSalProcEntry is initialized in library constructor as SAL entry.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync The constructor function of UEFI SAL Lib.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync The constructor function looks up the SAL System Table in the EFI System Configuration
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Table. Once the SAL System Table is found, the SAL Entry Point in the SAL System Table
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync will be derived and stored into a global variable for library usage.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync It will ASSERT() if the SAL System Table cannot be found or the data in the SAL System
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Table is not the valid data.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param ImageHandle The firmware allocated handle for the EFI image.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param SystemTable A pointer to the EFI System Table.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @retval EFI_SUCCESS The constructor always returns EFI_SUCCESS.

4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync // because the SAL entry is in ascending order with the entry type,
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync // the type 0 entry should be the first if exist.

4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync // Assure the SAL ENTRY Type is 0

4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync // Make sure the EntryPoint has the valid value
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync ASSERT ((mPlabel.EntryPoint != 0) && (mPlabel.GP != 0));
