This change adds a new HWCALC model, HWCALC_FXCG_MANAGER, which identifies Casio's official fx-CG Manager software. Both the Prizm and, to my surprise, the fx-CG Manager use the old RAM address of 88000000 (P1) and a8000000 (P2) instead of the new fx-CG 50 address of 8c000000 (P1) and ac000000 (P2). The VRAM is hence adjusted at startup to move hardcoded pointers into the proper space. Added to the kernel moving the VBR space dynamically on the Prizm, this allows gint to be fully compatible with these platforms. The fx-CG Manager is detected by its product ID made of 0xff. Also adds a proper interface to the R61524 driver, even though it's not any more complete than previously, and fixes an oversight where the HWURAM entry of the kernel data array was no longer computed since the TLB management change. As of now, the fx-CG Manager still has a bug regarding return-to-menu since returning from the main menu doesn't work very well and often loops. This has been seen occasionally on some Graph 90+E so it's unlikely to be a platform-specific problem.
