REVISION SUMMARY rockchip-s is probably the cheapest arm64 board usb, sdcard, ethernet, uart work most of the changes are ported from linux and openbsd the rk3308_cru.c file is basically generated with a set of conversion cpp macros (convert linux macros to freebsd macros) the regulator-pwm is crude and only supports continuous mode setting cpu frequency works temperature reading works ethernet media autoselect does not work with older u-boot 2017 ethernet does not work (phy regulator seems down) TEST PLAN you need to build u-boot from git with rock-pi-s-rk3308_defconfig + EFI support preloader and trust.img are from rockchip (there is no public source code for bl31), then use rk-loaderimage (ports) to convert u-boot-dtb.bin into u-boot.img i built a 13.x kernel and it works (all the files in the diff are from -CURRENT but they are mostly the same as 13.2 ) u-boot binaries available here link <https://drive.google.com/file/d/16jwXtRo7bmHexh-VTz6OdjV2fkH4IHgX/view> disk layout is similar to other rockchip sbcs, you need 16MB of empty space before the first/efi partition REVISION DETAIL https://reviews.freebsd.org/D40712 AFFECTED FILES sys/arm64/conf/std.rockchip sys/arm64/rockchip/clk/rk3308_cru.c sys/arm64/rockchip/if_dwc_rk.c sys/arm64/rockchip/rk_grf.c sys/arm64/rockchip/rk_pinctrl.c sys/arm64/rockchip/rk_pwm.c sys/arm64/rockchip/rk_spi.c sys/arm64/rockchip/rk_tsadc.c sys/arm64/rockchip/rk_usb2phy.c sys/conf/files sys/conf/files.arm64 sys/dev/extres/regulator/regulator_pwm.c sys/dev/extres/regulator/regulator_pwm.h EMAIL PREFERENCES https://reviews.freebsd.org/settings/panel/emailpreferences/ To: titus_edc.ro, #arm64, andrew, manu Cc: emaste, freebsd-arm-list, andrew
