IEEE 1275-1994 Standard for Boot (Initialization Configuration)
Firmware: Core Requirements and Practices
E.3.2.2 Bus-specific methods for bus nodes
A package implementing the scsi-2 device type shall implement the
following bus-specific method:
no-data-command ( cmd-addr -- error? )
Executes a simple SCSI command, automatically retrying under
certain conditions. cmd-addr is the address of a 6-byte command buffer
containing an SCSI command that does not have a data transfer phase.
Executes the command, retrying indefinitely with the same retry criteria
as retry-command.
error? is nonzero if an error occurred, zero otherwise.
NOTE no-data-command is a convenience function. It provides
no capabilities that are not present in retry-command, but for
those commands that meet its restrictions, it is easier to use.

Prevent buffer over-read in grub_machine_mmap_iterate. This was
causing phys_base from being calculated properly. This then
caused the wrong value to be placed in ramdisk_image within
struct linux_hdrs. Which prevented the ramdisk from loading on
boot.
Newer SPARC systems contain more than 8 available memory entries.
For example on a T5-8 with 2TB of memory, the memory layout could
