Hi hackers,

I'd like to share a few things I've been working on recently around
FreeBSD/arm64, and I'm looking for testers and code review before
attempting to upstream the relevant parts.

1) DPAA2: SFP+ now works on LX2160A (runtime configuration support)


https://github.com/freebsd/freebsd-src/compare/main...networkextension:freebsd-src:dpaa2-runtime-config

   In addition, an eSDHC (sdhci) driver attached via ACPI for the
   on-board TF/microSD card reader has started working:


https://github.com/freebsd/freebsd-src/compare/main...networkextension:freebsd-src:sdhci-fsl-acpi

   Testing on LX2160A-based boards (e.g. SolidRun HoneyComb) would be
   very welcome, especially with different SFP+ modules.

2) Thunderbolt: the Thunderbolt bridge (networking over TB) has
   started working. Work-in-progress trees:


https://github.com/networkextension/freebsd-src/tree/polar/thunderbolt-intree

https://github.com/freebsd/freebsd-src/compare/main...networkextension:freebsd-src:polar/thunderbolt-nhi-icm

   The second branch covers the NHI driver and ICM-based connection
   management. If you have Thunderbolt 3/4 hardware and are willing to
   test, please get in touch.

3) Swift toolchain on FreeBSD: three patches submitted upstream, one
   already merged:

   https://github.com/swiftlang/swift/pull/90143
   https://github.com/swiftlang/swiftly/pull/565
   https://github.com/apple/swift-nio-ssl/pull/587 (merged)

   Snapshot builds for FreeBSD are available here:

   https://github.com/networkextension/swift-freebsd

4) FreeBSD as a guest on Apple M-series SoCs using the macOS
   Virtualization.framework (vz):

   https://gist.github.com/networkextension/bfa6ee87d37c39300d9b72333e54d829

5) arm64 16K page size support, tested on Neoverse N1:


https://github.com/freebsd/freebsd-src/compare/main...networkextension:freebsd-src:arm64-16k-neoverse-n1
   https://gist.github.com/networkextension/b34041ea32383530a0e08e60d293240d

Any testing, review comments, or guidance on how best to split these
up for Phabricator reviews would be much appreciated. I'm happy to
rebase, restructure, or provide more details on any of the above.

Thanks,
yarshure
