Add support for Kevin, an RK3399-based convertible chromebook that is very similar to Bob. This patch is mostly based on existing support for Bob, with only minor changes for Kevin-specific things. Unlike other Gru boards, coreboot sets Kevin's center logic to 925 mV, so adjust it here in the dts as well. The rk3399-gru-kevin devicetree has an unknown event code reference which has to be defined, set it to the Linux counterpart. The new defconfig is copied from Bob with the diffconfig: DEFAULT_DEVICE_TREE "rk3399-gru-bob" -> "rk3399-gru-kevin" DEFAULT_FDT_FILE "rockchip/rk3399-gru-bob.dtb" -> "rockchip/rk3399-gru-kevin.dtb" VIDEO_ROCKCHIP_MAX_XRES 1280 -> 2400 VIDEO_ROCKCHIP_MAX_YRES 800 -> 1600 +TARGET_CHROMEBOOK_KEVIN y With this Kevin can boot from SPI flash to a usable U-Boot prompt on the display with the keyboard working, but cannot boot into Linux for unknown reasons. eMMC starts in a working state but fails to re-init, microSD card works but at a lower-than-expected speed, USB works but causes a hang on de-init. There are known workarounds to solve eMMC and USB issues. Cc: Marty E.
