qemu: arm: Remove platform specific function to get RNG device

2022-03-31T17:06:16Z

The QEMU platform has a function defined to get the random number generator(RNG) device. However, the RNG device can be obtained simply by searching for a device belonging to the RNG uclass. Remove the superfluous platform function defined for the QEMU platform for getting the RNG device.

board: gateworks: venice: determine dram size at runtime

2022-03-31T12:27:52Z

The SPL does not update the memory node with the dram size from EEPROM but instead we can use get_ram_size which does a simple memory test to determine the available RAM. Update PHYS_SDRAM_SIZE to 4GiB as that is the max used on the Venice boards. Signed-off-by: Tim Harvey Reviewed-by: Fabio Estevam

board: gw_ventana: gsc: fix GSC read/write functions

2022-03-31T12:27:51Z

commit 7c84319af9c7 ("dm: gpio: Correct use of -ENODEV in drivers") changed the return code for an I2C NAK from -ENODEV to -EREMOTEIO. Update the gsc_i2c_read and gsc_i2c_write functions for this change to properly retry the transaction on a NAK meaning the GSC is busy.

sunxi: Fix old GMAC pinmux setup

2022-03-26T00:16:06Z

Commit 5bc4cd05d7d4 ("sunxi: move non-essential code out of s_init()") moved the call to eth_init_board() from s_init() into board_init_f(). This means it's now only called from the SPL, which makes sense for most of the other moved low-level functions. However the GMAC pinmux and clock setup in eth_init_board() was not happy about that, so it broke the sun7i GMAC. Since Ethernet is of no use in the SPL anyway, just move the call into board_init(), which is only run in U-Boot proper. This fixes Ethernet operation for the A20 SoCs, which broke in v2022.04-rc1, with the above mentioned commit.

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.

k210: use the board vendor name rather than the marketing name

2022-03-15T09:43:11Z

"kendryte" is the marketing name for the K210 RISC-V SoC produced by Canaan Inc. Rather than "kendryte,k210", use the usual "canaan,k210" vendor,SoC compatibility string format in the device tree files and use the SoC name for file names. With these changes, the device tree files are more in sync with the Linux kernel DTS and drivers, making uboot device tree usable by the kernel.
