Subject: sun4m: Set HostID in NVRAM
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f9681f116ce06612b12ef41d8637f6659255ec98;p=qemu.git

sun4m: Set HostID in NVRAM

On SparcStations, the HostID field in the NVRAM is equal to the last
three bytes of the MAC address (which is also stored in the NVRAM).

This constant is used as an identification/serial number on Solaris.
