Build

1. Open command window, go to the WORKSPACE.
2. Go to the board folder you want to build. ex. Type cd Intel\AlderLakeOpenBoardPkg\AlderLakeSimics.
3. Type SetEdk2Env.bat.
4. Type prep and make prebuild finish for debug build, prep r for release build.
5. Type bld to build AlderLake BIOS image.
6. BIOS is generated at WORKSPACE\RomImages\BOARDNAME.fd.
7. Whole Image for Simics is generated at WORKSPACE\RomImages\MinPlatform\AlderLakeSimicsLP\ADL_Simics_DEBUG.bin

The user can run FITC tool to build full image for flash (BIOS + ME + DESC). The user can also burn the BIOS image to correct flash region directly.
