Skip asking github for latest hash, if we're requesting a specific hash

Means one less call to curl in that scenario

I wonder if any of this is needed.
I believe rpi-update and rpi-update HEAD both get the latest code, so just the line
FW_REV=${FW_REV:-HEAD} may be all that is needed.

just the line FW_REV=${FW_REV:-HEAD} may be all that is needed.

That would end up writing HEAD into /boot/.firmware_revision though, which probably isn't very useful ;-)

(and I guess https://github.com/Hexxeh/rpi-update/blob/master/rpi-update#L355 means that you'd then only be able to rpi-update just the once?)

[popcornmix]

Yes, good point.

@lurch what is the conclusion on this one? That the RP is ready to merge, that it should be dismissed or?

[lurch]

IMHO this patch is still worth merging. I've just rebased it on top of the latest version of master.
