In the Base Null instance: - QemuFwCfgS3Enabled() returns constant FALSE. This is unique to the Base Null instance, and the function is already present in "QemuFwCfgS3Base.c". - The QemuFwCfgS3CallWhenBootScriptReady() function must never be called (according to the documentation, given the above). This is also unique to the Base Null instance, so implement the function in "QemuFwCfgS3Base.c". - Consequently, the QemuFwCfgS3ScriptWriteBytes(), QemuFwCfgS3ScriptReadBytes(), QemuFwCfgS3ScriptSkipBytes(), and QemuFwCfgS3ScriptCheckValue() functions must never be called either. This behavior is not unique to the Base Null instance (it will be shared with the PEI fw_cfg instance), so add these functions to "QemuFwCfgS3BasePei.c".

# Base Null library instance of the QemuFwCfgS3Lib class.
|
|
#
|
|
# This library instance returns constant FALSE from QemuFwCfgS3Enabled(), and
|
|
# all other library functions trigger assertion failures. It is suitable for
|
|
# QEMU targets and machine types that never enable S3.
