rockchip: rk3399: Add support for chromebook_kevin

2022-03-18T10:12:03Z

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.

rockchip: gru: Set up SoC IO domain registers

2022-03-18T10:12:03Z

The RK3399 SoC needs to know the voltage value provided by some regulators, which is done by setting relevant register bits. Configure these the way other RK3399 boards do, but with the same values as are set in the equivalent code in coreboot.

scripts: Makefile.lib: generate dsdt_generated.c instead of dsdt.c

2022-02-25T16:21:24Z

There is a conflict between the static file lib/acpi/dsdt.c and the file dsdt.c generated dynamicaly by scripts/Makefile.lib. When a mrproper is done, the static file dsdt.c is removed. If a build with acpi enabled is launched after, the following error is raised: CC lib/acpi/acpi_table.o make[2]: *** No rule to make target 'lib/acpi/dsdt.asl', needed by 'lib/acpi/dsdt.c'. Stop. scripts/Makefile.build:394: recipe for target 'lib/acpi' failed To avoid such error, the generated file is named dsdt_generated.c instead of dstdt.c.

treewide: Use OF_REAL instead of !OF_PLATDATA

Now that we have a 'positive' Kconfig option, use this instead of the negative one, which is harder to understand. Signed-off-by: Simon Glass

imx: Finish migration of IMX_CONFIG to Kconfig

2021-08-31T21:46:37Z

- Provide a default Kconfig value of the default script - Largely continue to define this via the board Kconfig file - For the boards that select a script based on defconfig rather than TARGET, keep this within the defconfig. Signed-off-by: Tom Rini

x86: coral: Allow booting from coreboot

2021-07-15T11:50:14Z

Set up coral so that it can boot from coreboot, even though it is a bare-metal build. This helps with testing since the same image can be used in both cases. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: coral: Show memory config and SKU ID on startup

2021-03-27T03:26:48Z

Provide the model information through sysinfo so that it shows up on boot. For memconfig 4 pins are provided, for 16 combinations. For SKU ID there are two options: - two pins provided in a ternary arrangement, for 9 combinations. - reading from the EC Add a binding doc and drop the unused #defines as well.
