To be able to boot ELKS from the Flash of my SBC, tune the existing ROMFS to store the root filesystem in that Flash, as the kernel with the CONFIG_ROMCODE option.

Guidelines:

Implementation roadmap:

  • add a dummy /dev/rom0 device
  • force root device to /dev/rom in case of ROM boot
  • add a mkromfs tool to create the FS (romfs.bin)
  • add configuration parameter CONFIG_ROMFS_BASE
  • low level routines for direct access to filesystem in ROM
  • use low level routines in existing ROMFS code
  • support device nodes in filesystem (to allow /bin/sh to use /dev/tty1)
