The Semihalf team has been working on adding the FreeBSD support for the NXP LS1028A SoC, as well as its GPU-less variant (NXP LS1027A).

NXP LS1028A/LS1027A SoC is a dual-core 64-bit ARMv8 Cortex-A72 application processor with high-speed peripherals such as 2 Time-Sensitive Networking-capable (TSN) Ethernet controllers, quad-port TSN-enabled switch, PCIE, SD/MMC, USB3.0 and others.

The original support was extended in the following way:

  • ENETC Ethernet driver

    • Add support for PHY interrupts

    • Fix VID/mcast address hash calculation

    • Serialize MDIO transactions

    • Allow loading driver as a module

  • Improvements in the FSL SDHCI driver

    • Add support for HS200/HS400 modes

    • Add full support for software reset

    • Provide more accurate clk calculation

    • Implement pulse width detection errata

    • Fix vccq reconfiguration

  • FLEX SPI NOR controller driver

  • Additional features:

    • TMP461 thermal sensor driver

    • PCF85063 RTC driver driver

    • TCA6408 I2C GPIO expander driver

TODO:

  • Improve MMC HS200/HS400 support for other SoCs using the FSL SDHCI controller.
