Core System & NVSRAM Driver Architecture (core.h)

The Core System driver manages chassis-level supervisor logic and non-volatile memory:

• Chassis Controller (mmapCore.h, base 0x0000): Master FPGA configuration registers, board soft reset, hardware watchdog kick registers, and board status flags.
• NVSRAM Memory Controller (coreNvsramMap.h, base 0x0000): High-reliability battery-backed SRAM access for flight history, PBIT/CBIT fault bitmasks, and factory calibration tables.
