Caveats: Support for the internal SATA controller is currently missing,
as is support for framebuffer resolutions other than 720x480. These
deficiencies will be remedied soon.
Special thanks to Peter Grehan for providing the hardware that made this
port possible, and thanks to Geoff Levand of Sony Computer Entertainment
for advice on the LV1 hypervisor.
The controller is commonly found on DM&P Vortex86 x86 SoC. The
driver supports all hardware features except flow control. The
flow control was intentionally disabled due to silicon bug.
DM&P Electronics, Inc. provided all necessary information including
sample board to write driver and answered many questions I had.
Many thanks for their support of FreeBSD.

usually false while on pSeries we have found that it is true. The real-mode?

BIOS does not support ACPI. The other options in the menu retain their
existing numbers, option 2 is simply blanked out (and '2' is ignored).

was incorrect as further down the road cons_probe() calls malloc() so the
former can't be called before init_heap() has succeed. Instead just exit
to the firmware in case init_heap() fails like OF_init() does when hitting
a problem as we're then likely running in a very broken environment where
hardly anything can be trusted to work.
OF loader on systems where address cells and size cells are both 2 (the
Mambo simulator) and fix an error where cons_probe() was called before
init_heap() but used malloc() to set environment variables.

- Teach gptboot and gptzfsboot about new files. I haven't touched the
rest, but there is still a lot of code duplication to be removed.
- Implement full GPT support. Currently we just read primary header and
partition table and don't care about checksums, etc. After this change we
verify checksums of primary header and primary partition table and if
there is a problem we fall back to backup header and backup partition
table.
- Clean up most messages to use prefix of boot program, so in case of an
error we know where the error comes from, eg.:
gptboot: unable to read primary GPT header
- If we can't boot, print boot prompt only once and not every five
seconds.
- Honour newly added GPT attributes:
bootme - this is bootable partition
bootonce - try to boot from this partition only once
bootfailed - we failed to boot from this partition
- Change boot order of gptboot to the following:
1. Try to boot from all the partitions that have both 'bootme'
and 'bootonce' attributes one by one.
2. Try to boot from all the partitions that have only 'bootme'
attribute one by one.
3. If there are no partitions with 'bootme' attribute, boot from
the first UFS partition.
- The 'bootonce' functionality is implemented in the following way:
1. Walk through all the partitions and when 'bootonce'
attribute is found without 'bootme' attribute, remove
'bootonce' attribute and set 'bootfailed' attribute.
'bootonce' attribute alone means that we tried to boot from
this partition, but boot failed after leaving gptboot and
machine was restarted.
2. Find partition with both 'bootme' and 'bootonce' attributes.
3. Remove 'bootme' attribute.
4. Try to execute /boot/loader or /boot/kernel/kernel from that
partition. If succeeded we stop here.
5. If execution failed, remove 'bootonce' and set 'bootfailed'.
6. Go to 2.
If whole boot succeeded there is new /etc/rc.d/gptboot script coming
that will log all partitions that we failed to boot from (the ones with
'bootfailed' attribute) and will remove this attribute. It will also
find partition with 'bootonce' attribute - this is the partition we
booted from successfully. The script will log success and remove the
attribute.
All the GPT updates we do here goes to both primary and backup GPT if
they are valid. We don't touch headers or partition tables when
checksum doesn't match.

and sys/boot/pc98/boot2, do not simply assign 'gcc' to CC, since compile
flags are sometimes passed via this variable, for example during the
build32 stage on amd64. This caused the 32-bit libobjc build on amd64
to fail.
Instead, only replace the first instance of clang (if any, including
optional path) with gcc, and leave the arguments alone.

it possible to boot from ZFS RAIDZ for example from within VirtualBox.
The problem with VirtualBox is that its BIOS reports only one disk present.
If we choose to ignore this report, we can find all the disks available.
We can't have this work-around to be turned on by default, because some broken
BIOSes report true when it comes to number of disks, but present the same disk
multiple times.
- Change putc_func_t to use a char instead of an int for the character.
- Make functions and variables not used outside of this source file static.
- Remove unused prototypes and variables.
- The OFW read and seek methods take 3 and not 4 input arguments.
Before the change it wasn't possible and the following error was printed:
ZFS: can only boot from disk, mirror or raidz vdevs
Now if the original vdev (the one we are replacing) is still present we will
read from it, but if it is not present we won't read from the new vdev, as it
might not have enough valid data yet.
