Splits the NorFlashDxe driver to introduce a NorFlashDeviceLib that implements the specifics for the respective flash. This will allow us to plug different libraries implementing functionality of various NOR Flash. The flash specific code in NorFlashDxe has been moved to P30NorFlashDeviceLib library. 2. Adds support for CadenceQspiNorFlashDeviceLib which is used by N1Sdp platform along with NorFlashDxe driver. N1Sdp uses an emulated variable storage on DDR memory for the variable storage. But this emulated variable storage is a volatile memory and so the values of variables can't persist on next reboot or in power cycle. In N1Sdp platform, the SoC is connected to IOFPGA which has a Cadence Quad SPI (QSPI) controller. This QSPI controller manages the flash chip device via QSPI bus. With these changes we use this NOR flash device for persistent variable storage. 3. Fixes memory leak in NorFlashCreateInstance() function. v3: - Fixed code review comments - Added 3 new patches for the following: - Fix memory leak in NorFlashCreateInstance() - Make local functions STATIC in NorFlashDxe - Remove unimplemented functions from NorFlash.h v2: - Fixed code review comments - Split the NorFlashDxe driver and moved flash specific code to P30NorFlashDeviceLib - Added NOR flash Dxe Driver for N1Sdp as a library instead of a driver Link to branch with the patches in this series - https://github.com/sah01Kaushal/edk2-platforms/tree/n1sdp_persistent_stor= age_v3 Links to
