2014-06-19OvmgPkg: QemuFwCfgLib: export QEMU_FW_CFG_FNAME_SIZELaszlo Ersek
Names of firmware configuration files always take 56 bytes (including at least one terminating NUL byte). Expose this constant to all consumers of QemuFwCfgLib because further interfaces may depend on it.

2014-01-03OvmfPkg: QemuFwCfgLib: implement for SECLaszlo Ersek
The QemuFwCfgSecLib library instance - is stateless, - has no library constructor, - is available to SEC client code, - must be queried with QemuFwCfgIsAvailable() before use, - is restricted to SEC in order to limit the explicit querying requirement. (There is no current user.)

2014-01-03OvmfPkg: QemuFwCfgLib: extract stateful implementationLaszlo Ersek
The current implementation of QemuFwCfgLib is: - stateful - implicitly initialized in the library constructor. OVMF's SEC runs from read-only memory/flash. When the library is linked into a SEC binary (which currently never happens), the "mQemuFwCfgSupported" global variable becomes read-only, making the library non-functional. Extract the stateful, implicitly initialized library implementation into a separate file, making room for a stateless, explicitly queried implementation that's usable in SEC. Restrict the stateful implementation to the current, non-SEC clients.

2014-01-03OvmfPkg: QemuFwCfgLib: introduce InternalQemuFwCfgIsAvailable()Laszlo Ersek
This internal function allows separation of library-internal and for-clients external availability of fw_cfg. The interface contract of QemuFwCfgIsAvailable() is changed so that now it may modify fw_cfg state. All current users are compliant with the new contract.
