    _______________________________________________________

Details:

A few coreboot-specific commands (like cbmemc and lscoreboot) have recently
been made available on all x86 platforms, not just i386-coreboot. However, all
these commands depend on coreboot tables being present in the system when run.
Otherwise grub_linuxbios_table_iterate() calls grub_fatal() and GRUB
terminates.

However grub_linuxbios_table_iterate() is called when initialising cbmemc.mod.
This is problematic since the module is loaded even when one wants to just
view the help text for the "cbmemc" command, which has an admittedly quite
cryptic name.

The grub_fatal() call should probably be moved somewhere else (coreboot
platform init?), while the commands themselves should fail non-fatally.
