board: gateworks: venice: determine dram size at runtime

2022-03-31T12:27:52+00:00

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.

arm: socfpga: vining: Fix mtdparts for 2x256 MiB SF variant

2022-03-28T19:49:03+00:00

The 2x256 MiB SF variant of this system has 192 MiB rootfs MTD partition
containing UBI on SF0, use the correct size in U-Boot environment, else
U-Boot cannot mount UBI and boot on this variant.

mtd: gpmi: fix the bch setting backward compatible issue

2022-03-28T12:22:17+00:00

Previous u-boot code changed the default bch setting behavior and caused
backward compatible issue. This fix choose the legacy bch geometry back
again as the default option. If the minimum ecc strength that NAND chips
required need to be chosen, it can be enabled by either adding DT flag
"fsl,use-minimum-ecc" or CONFIG_NAND_MXS_USE_MINIMUM_ECC in configs. The
unused flag "fsl,legacy-bch-geometry" get removed.

Fixes: 51cdf83eea (mtd: gpmi: provide the option to use legacy bch geometry)

efi_loader: remove efi_disk_is_system_part()

2022-03-20T10:03:06+00:00

The block IO protocol may be installed on any handle. We should make
no assumption about the structure the handle points to.

efi_disk_is_system_part() makes an illegal widening cast from a handle
to a struct efi_disk_obj. Remove the function.

rockchip: rk3399: Add support for chromebook_kevin

2022-03-18T10:12:03+00:00

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.

rockchip: bob: Enable more configs

2022-03-18T10:12:03+00:00

This patch enables some configs that should be working on the Bob board,
based on what is observed to work on the Kevin board.

The Bob board uses an Embedded DisplayPort panel compatible with the
simple panel and Rockchip eDP drivers. Its backlight is controlled by
the Chromium OS Embedded Controller Pulse Width Modulator. Enable these
for the board.

Also set VIDEO_ROCKCHIP_MAX_{XRES,YRES} to 1280x800, the resolution of
its panel. This had to be done for the Kevin board, but it's untested if
this is actually necessary for Bob.

The Rockchip video driver needs to assert/deassert some resets, so also
enable the reset controller. RESET_ROCKCHIP defaults to y for this board
when DM_RESET=y, so it's enough to set that.

The Bob board has two USB 3.0 Type-C ports and one USB 2.0 Type-A port
on its right side. Enable the configs relevant to USB devices so these
can be used. This is despite a known issue with RK3399 boards where USB
de-init causes a hang, as there is a known workaround.

Some other rk3399-based devices enable support for the SoC's random
number generator in commit a475bef5340c ("configs: rk3399: enable rng on
firefly/rock960/rockpro64"), as it can provide a KASLR seed when booting
using UEFI. Enable it for Bob as well.

The default misc_init_r() for Rockchip boards sets cpuid and ethernet
MAC address based on e-fuse block. A previous patch extends this on Gru
boards to set registers related to SoC IO domains as is necessary on
these boards. Enable this function and configs for it on Bob.

The microSD card slot on this board (and others based on Gru) is
connected to a GPIO controlled regulator (ppvar-sd-card-io), which must
be operable by U-Boot. Enable the relevant config option to allow this.

Bob boards also use the Winbond W25Q64DW SPI flash chip, enable support
for Winbond SPI flash chips in the board config so U-Boot can boot with
this chip.
