4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync// Declaration for internal functions
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync Executes an SMBus operation to an SMBus controller.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync This function provides a standard way to execute Smbus script
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync as defined in the SmBus Specification. The data can either be of
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync the Length byte, word, or a block of data.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param SmbusOperation Signifies which particular SMBus hardware protocol instance
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync that it will use toexecute the SMBus transactions.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param SmBusAddress The address that encodes the SMBUS Slave Address,
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync SMBUS Command, SMBUS Data Length, and PEC.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param Length Signifies the number of bytes that this operation will
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync do. The maximum number of bytes can be revision specific
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync and operation specific.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param Buffer Contains the value of data to execute to the SMBus slave
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync device. Not all operations require this argument. The
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync length of this buffer is identified by Length.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @param Status Return status for the executed command.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync This is an optional parameter and may be NULL.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync @return The actual number of bytes that are executed for this operation.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync The constructor function caches the pointer to Smbus protocol.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync The constructor function locates Smbus protocol from protocol database.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync It will ASSERT() if that operation fails and it will always return EFI_SUCCESS.
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.
