This prevented a number of machines in the FreeBSD.org cluster from
booting due to "ZFS: i/o error - all block copies unavailable"
after an unclean shutdown.
The new bcache code does not know the size of the disk, and therefore may attempt to read past the end of the disk while trying to fill its read-ahead cache.
This is usually not an issue, it fails gracefully on all of my machines, but some BIOSes seem to retry the reads for up to 30 seconds each, resulting in a long stall during boot

FDT overlays is de-facto standard for describing expansion boards like
Beaglebone capes or Raspberry Pi shields. The ides is to have basic
DTB for base board and overlays DTB for shields/capes and to construct
final DTB either using human-readable configuration or some
self-discovery mechanism. I believe this approach can also be expanded
to support dynamically loadable FPGA bitstreams on systems like
Zedboard/Zybo.
Overlaying process is simmilar to executable link process for
binaries: each DTB has "exported" symbols and "undefined" symbols, the
latter are resolved using information for the former obtained from
base DTB or one of the overlays applied earlier (more rare case).
This symbols information is not generated by standard dtc that FreeBSD
has in base system, patched[1] version required to produces
overlay-compatible blobs. So although DTB files generated by
buildkernel do not support overlays there are enough
vendor/community-provided DTB blobs ciruclating around to justify
committing this change to ubldr.
This commit introduces handler for "fdt_overlays" variable that can be
defined either as a loader env variable or U-Boot env variable.
fdt_overlays is comma-separated list of .dtbo files located in
/boot/dtb/ directory along with base .dtb. ubldr loads files and
applies them one-by-one to base .dtb and then passes result blob to
the kernel.

The block cache implementation in loader has proven to be almost useless, and in worst case even slowing down the disk reads due to insufficient cache size and extra memory copy.
Also the current cache implementation does not cache reads from CDs, or work with zfs built on top of multiple disks.
Instead of an LRU, this code uses a simple hash (O(1) read from cache), and instead of a single global cache, a separate cache per block device.
The cache also implements limited read-ahead to increase performance.
To simplify read ahead management, the read ahead will not wrap over bcache end, so in worst case, single block physical read will be performed to fill the last block in bcache.

This revision suggests dtsi patches to be used with the original OpenWRT
dtsi files so we can re-use what has already been done in OpenWRT for the
Mediatek/Ralink SoCs.
The only thing that is required after importing this revision should be
the following:
1. Import OpenWRT dts/dtsi files into sys/gnu/dts/mips
2. Run the following script in sys/gnu/dts/mips:
for f in `ls [mr]t*.dtsi`; do
printf "\n#include <fbsd-$f>\n" > $f
done
This will apply our dtsi patches to OpenWRT's dtsi files and will allow us
to re-use dts/dtsi files for ~170 Mediatek/Ralink boards.
Currently our drivers are not 100% compatible with OpenWRT's dts files, but
they're compatible enough.
We can add more functionality in the future that would better leverage the
OpenWRT work as well.

because when there's no static hints (the default), this value can be
fetched from the hint. When there is a static hints file, the hint
passed from the boot loader to the kernel is ignored, but for the BIOS
case we're able to find it anyway. However, with UEFI, the fallback
doesn't work, so we get a panic instead.
Switch to acpi.rsdp and use TUNABLE_ULONG_FETCH instead. Continue to

Note: The PCIe driver is pure mash at this moment. It will be reworked

After ARM_INTRNG introduction, MPIC code needed several modifications:
- IRQ resource and its handler added
- several DEVMETHODs of INTRNG interface implemented
- defines enhanced to ensure code compiles as well for AXP as for A38X
- added dummy MSI_IRQ, ERR_IRQ defines for Armada38x
- MPIC driver was added to files.armada38x, ARM_INTRNG option enabled in

Instead of modifying Armada38X DTS, offsets to CPU registers defined in

Until now, ubldr has been trying to locate the U-Boot API using a hint
address (U-Boot's current stack pointer), aligning it to 1MiB and going
over a 3MiB (or 1MiB in case of MIPS) memory region searching for a
valid API signature.
This change introduces an alternative way of doing this, namely the
following:
- both U-Boot's bootelf and go commands actually pass argc and argv to
the entry point (e.g., ubldr's start function, but they should also
be passed over to main() transparently)
- so, instead of trying to go and look for a valid API signature, we
look at the parameters passed to main()
- if there's an option '-a' with argument, which is a valid hexadecimal
unsigned long number (x), we try to verify whether we have a valid
API signature at address x. If so - we use it. If not - we fallback
to the original way of locating the API signature.
The U-Boot change, which causes the API structure address to be
exported as an environment variable, was committed to mainline U-Boot
as commit 22aa61f707574dd569296f521fcfc46a05f51c48

For the tests I've used FAT32 disk images (as FAT32 is supported by U-boot),
which include /boot/kernel/kernel and /boot/kernel/ubldr.bin
In U-boot I do:
fatload ide 0 <LOAD_ADDR> /boot/kernel/ubldr.bin; go <LOAD_ADDR>
where LOAD_ADDR is 80800000 for 32-bit and ffffffff80800000 for 64-bit
