HEADS UP: NXP LS1046A SoC support in the tree

[Marcin Wojtas]

Hello all,

On behalf of the Semihalf team I'd like to announce that starting from
r365054 FreeBSD is ready to run NXP LS1046A system-on-a-chip with most
of the interfaces supported.

LS1046A are quad-core 64-bit ARMv8 Cortex-A72 processors with
integrated packet processing acceleration and high speed peripherals
including 10 Gb Ethernet, PCIe 3.0, SATA 3.0 and USB 3.0 for a wide
range of networking, storage, security and industrial applications. It
is confirmed that at least some parts of the kernel support (such as
SDHCI) was successfully used on the Solid-Run LX2K Honeycomb
development platform.

Below is the port status together with the features, which were
originally developed on top of the release/11.2.0 that have made their
way to FreeBSD-HEAD:
* LS1046A core support (Quad-CA72 SMP, timers, IRQS, UART)
  - already working in vanilla FreeBSD-HEAD before
* DWC3 USB3.0 host controller driver (FreeBSD-HEAD
  version developed by manu@)
* VF610 I2C controller (adjusted to work with the LS1046A)
* TI LM75 temperature sensor (adjusted to work with the LS1046A)
* QorIQ platform clockgen
* LS1046A CPU clockgen
* LS1046A GPIO
* RX8803 I2C RTC
* TCA6416 I2C GPIO expander
* LS1046A AHCI
* LS1046A SDHCI

The major out-of-tree components are that albeit working on top of
release/11.2.0, still require significant effort to adopt to
FreeBSD-HEAD:
* DPAA network controller support
* QSPI controller support

This was a joined effort of Semihalf and Alstom Group (main
development sponsor), in particular:
Laurent Muller
David Fontaine
Yannis Planus
Artur Rojek
Dawid Górecki
Kornel Dulęba
Kamil Koczurek
Michał Stanek
Jacek Klimkowicz

Best regards,
