This is a minimalistic boot ROM written specifically for use with QEMU.
It supports loading the second-stage loader from SPI flash into RAM, SMP
boot, and not much else.

+- npcm7xx_bootrom.bin is a simplified, free (Apache 2.0) boot ROM for Nuvoton
+ NPCM7xx BMC devices. It currently implements the bare minimum to load, parse,
+ initialize and run boot images stored in SPI flash, but may grow more
+ features over time as needed. The source code is available at:
