* EmbeddedPkg: Extend NvVarStoreFormattedLib LIBRARY_CLASSMarcin Wojtas2019-04-291-1/+1
| | | | | | | | | | Latest change allowed to add dependency on NvVarStoreFormattedLib for the DXE_DRIVER modules. Although effectively it is hooked using the 'NULL' class, extend the LIBRARY_CLASS with according type for consistency sake.

* EmbeddedPkg: Allow DXE_DRIVER to depend on NvVarStoreFormattedLibMarcin Wojtas2019-04-251-2/+2
| | | | | | | | | | | | | | | Some modules (such as FaultTolerantWriteDxe) use the FlashNvStorage PCDs (PcdFlashNvStorageFtw*). In case the flash contents are not mapped in memory, the module loading order of the FVB driver may become important. To handle above, this patch allows to hook the dependency of desired DXE_DRIVER type module in the .DSC file via NvVarStoreFormattedLib NULL resolution.

* EmbeddedPkg: introduce NvVarStoreFormattedLibLaszlo Ersek2018-04-122-0/+93
Some platforms don't format a variable store template at build time; instead they format the non-volatile varstore flash chip during boot, dynamically. Introduce NvVarStoreFormattedLib to enable such platforms to delay the "variable read" service drivers until the platform specific module(s) report that the variable store has been formatted. The platform-specific module that performs the formatting during startup is usually an FVB or MM FVB driver. Under the proposed scheme, it becomes responsible for installing gEdkiiNvVarStoreFormattedGuid with a NULL interface in the protocol database. In turn, the platform DSC will hook NvVarStoreFormattedLib into the variable service driver, to make the latter wait for the FVB driver. Platforms that need not delay the variable service driver like this may still use the same FVB driver; gEdkiiNvVarStoreFormattedGuid will simply be ignored.
