=== NXP LS1028A/1027A SoC support Contact: Kornel Dulęba <[email protected]> + Contact: Artur Rojek <[email protected]> + Contact: Hubert Mazur <[email protected]> + Contact: Wojciech Macek <[email protected]> The Semihalf team has been working on adding the FreeBSD support for the link:https://www.nxp.com/products/processors-and-microcontrollers/arm-processors/layerscape-processors/layerscape-1028a-applications-processor:LS1028A[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 link:https://cgit.freebsd.org/src/log/sys/dev/enetc[driver] ** Add support for PHY interrupts ** Fix VID/mcast address hash calculation ** Serialize MDIO transactions ** Allow loading driver as a module * Improvements in the link:https://cgit.freebsd.org/src/log/sys/dev/sdhci/sdhci_fsl_fdt.c[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 link:https://cgit.freebsd.org/src/log/sys/dev/flash/flexspi/flex_spi.c[driver] * Additional features: ** TMP461 thermal sensor link:https://cgit.freebsd.org/src/log/sys/dev/iicbus/tmp461.c[driver] ** PCF85063 RTC driver link:https://cgit.freebsd.org/src/log/sys/dev/iicbus/rtc/pcf85063.c[driver] ** TCA6408 I2C GPIO expander link:https://cgit.freebsd.org/src/log/sys/dev/iicbus/gpio/tca6408.c[driver] TODO: * Improve MMC HS200/HS400 support for other SoCs using the FSL SDHCI controller.
