  Log:
  Add eeprom(8), a utility to display and modify system configurations
  stored in EEPROM or NVRAM. It's inspired by the NetBSD eeprom(8) and
  the SunOS/Solaris eeprom(1M) utilities. Currently, this eeprom(8)
  only supports systems equipped with Open Firmware and is only tested
  on Sun machines but should work on any platform using Open Firmware.
  A bit more specific, eeprom(8) can be used on these systems to do the
  same under FreeBSD as can be done using the printenv and setenv
  commandos in the boot monitor. One thing that only hardly can be done
  using the boot monitor but easily with eeprom(8) is to write a logo
  to the "oem-logo" property. eeprom(8) may also be useful to recover
  the boot monitor password (in the default configuration only as root,
  of course), i.e. when the boot monitor allows you to boot but you
  can't alter the configuration because the password is unknown. The
  man page may also be a useful reference of the various configuration
  variables.
  
  The idea of eeprom(8) is that handlers can be written to add support
  for any firmware that stores such configuration in EEPROM or NVRAM;
  sort of e.g. eeprom(1M) on Solaris/x86 is used to turn PAE-support
  on and off (stored in a file then, not hardware). In FreeBSD, a
  candidate for this would be a handler for the EFI boot environment
  for FreeBSD/ia64.
  
  eeprom(8) uses some code from NetBSD (eeprom.c and the base for
  eeprom.8), the handler for the Open Firmware /options node
  (ofw_options.[c,h]) was written using ofw_util.[c,h] from ofwdump(8).
