The boot1.elf is too fat for 30k, it's now 32k on powerpc64, and 34k on powerpc. Without this, boot1 will fail with odd behaviors.

As this is evaluation hardware with only a few users, and there is a lack of information add a warning when booting on this hardware.

In such cases, boot1 would only try to read the entire device rather than checking for partitions. Instead of panic'ing, fall back to reading the partitions as normal in such situations. This was preventing boot of installed systems on some versions of PowerKVM. PR: kern/211599 Approved by: re (gjb) 2016-09-01T20:01:38Z Glen Barber gjb@FreeBSD.org 2016-09-01T20:01:38Z urn:sha1:2c8efb0f82b9ba1d25e6d47ea8e18176b6e406ca MFC r304966 (peter): The read-ahead code from r298230 made it likely the boot code would read beyond the end of disk. r298900 added code to prevent this. Some BIOSes cause significant delays if asked to read past end-of-disk. We never trusted the BIOS to accurately report the sectorsize of disks before and this set of changes. Unfortuately they interact badly with the infamous >2TB wraparound bugs. We have a number of relatively-recent machines in the FreeBSD.org cluster where the BIOS reports 3TB disks as 1TB. With pre-r298900 they work just fine. After r298900 they stop working if the boot environment attempts to access anything outside the first 1TB on the disk. 'ZFS: I/O error, all block copies unavailable' etc. It affects both UFS and ZFS if they try to boot from large volumes. This change replaces the blind trust of the BIOS end-of-disk reporting with a read-ahead clip to prevent reads crossing the of end-of-disk boundary. Since 2^32 (2TB) size reporting truncation is not uncommon, the clipping is done on 2TB aliases of the reported end-of-disk. ie: a 3TB disk reported as 1TB has readahead clipped at 1TB, 3TB, 5TB, ... as one of them is likely to be the real end-of-disk. This should make the loader on these broken machines behave the same as traditional pre-r298900 loader behavior, without disabling read-ahead.
