Comment 18 for bug 1714750

Somebody re-reported this which reminded me that we forgot to tidy up the loose ends here.
Current status:
 * this is fixed in upstream u-boot with their commit 610eec7f0593574 (committed October 2017, and in u-boot release v2017.11 and later)
 * in QEMU's release process we put in a workaround in our commit d0dead3b6df7f6cd97 which puts the u-boot sources in their own tarball rather than extracted; this went into QEMU release 2.11.0
 * we are still shipping the same old version of u-boot we were in 2.10

So ideally we'd finish fixing this bug report by:
 * updating our u-boot to some version v2017.11 or later
 * removing the d0dead3b6df7f6cd97 workaround
