particular interest in (and support for) SRI International and the
University of Cambridge's BERI FPGA soft-core processor. This includes
micro device drivers for the Altera JTAG UART console, memory-mapped
flash, and the Altera SD Card IP core in both boot2 and loader. boot2
can be written to the on-board Intel StrataFlash on the DE4 board, and
loader can be placed in StrataFlash or the SD Card.
Plenty of XXX comments, but works quite well locally in practice and I
am using it daily. Although I had originally ported the ARM version
of boot2, the current version is x86-derived as that proved more
feature-complete. As we don't currently use partitions on our flash
disks, support for that has been commented out relative to x86, but
would be easy to add back. FDT support has not yet been hooked up,
although some skeleton parts have been put in place for that.
This may well be a useful starting point for ports to other 32-bit and
64-bit MIPS-ISA systems.
This merge is synchronised to CheriBSD github commit
e41d74fd71, but with some additions of
$FreeBSD.

A 32-bit libstand is needed on 64-bit platforms for use by various
bootloaders. Previously only the 32-bit version was built, installed as
/usr/lib/libstand.a.
A new 64-bit libstand consumer will arrive in the near future, so move
the bootloader-specific 32-bit version to sys/boot/libstand32/.
Explicitly link against this version in the 32-bit loaders.

- Similar to the hack for bootinfo32.c in userboot, define
_MACHINE_ELF_WANT_32BIT in the load_elf32 file handlers in userboot.
This allows userboot to load 32-bit kernels and modules.
- Copy the SMAP generation code out of bootinfo64.c and into its own
file so it can be shared with bootinfo32.c to pass an SMAP to the i386
kernel.
- Use uint32_t instead of u_long when aligning module metadata in
bootinfo32.c in userboot, as otherwise the metadata used 64-bit
alignment which corrupted the layout.
- Populate the basemem and extmem members of the bootinfo struct passed
to 32-bit kernels.
- Fix the 32-bit stack in userboot to start at the top of the stack
instead of the bottom so that there is room to grow before the
kernel switches to its own stack.
- Push a fake return address onto the 32-bit stack in addition to the
arguments normally passed to exec() in the loader. This return
address is needed to convince recover_bootinfo() in the 32-bit
locore code that it is being invoked from a "new" boot block.
- Add a routine to libvmmapi to setup a 32-bit flat mode register state
including a GDT and TSS that is able to start the i386 kernel and
update bhyveload to use it when booting an i386 kernel.
- Use the guest register state to determine the CPU's current instruction
mode (32-bit vs 64-bit) and paging mode (flat, 32-bit, PAE, or long
mode) in the instruction emulation code. Update the gla2gpa() routine
used when fetching instructions to handle flat mode, 32-bit paging, and
PAE paging in addition to long mode paging. Don't look for a REX
prefix when the CPU is in 32-bit mode, and use the detected mode to
enable the existing 32-bit mode code when decoding the mod r/m byte.

generally bring the kernel config into line with what we have for other
Marvell/Kirkwood systems (add lots of useful devices and options).
One particularly notable addition amongst the kernel config changes is
USB_HOST_ALIGN=32, which may help eliminate data corruption on USB drives.

This is because several Makefiles under sys/boot/i386 and sys/boot/pc98
use ${LD} directly to link, and the normal LDFLAGS value should not be

This fix is not ideal as it assumes a 32 bit int, but does fix the issue
for most cases.

Use the published compatible strings (our own invention, "ti,mmchs" is
still accepted as well, for now).
Don't blindly turn on 8-bit bus mode, because even though the conroller
supports it, the board has to be wired appropriately as well. Use the
published property (bus-width=<n>) and honor all the valid values (1,4,8).
The eMMC device on a Beaglebone Black is wired for 8-bit, update the dts.
The mmchs controller can inherently do both 1.8v and 3.0v on the first
device and 1.8v only on other devices, unless an external transceiver is
used. Set the voltage automatically for the first device and honor
the published fdt property (ti,dualvolt) for other devices.
Thanks go to Ilya Bakulin for figuring out the voltage compatibility stuff.
The imx6.dtsi is incomplete, but has enough to support devices that work

It also allows any combination of the units to be en/disabled in the
