[PATCH 1/3] smegw01: Allow booting the Yocto image by default
by Fabio Estevam 12 Jul '21

12 Jul '21

On the Yocto image there is a single partition and the kernel and dtb are present in the 'boot' directory. Change it accordingly so that the board can boot the Yocto image by default. Use the generic 'load' command instead, which is able to read from an ext4 partition.

[PATCH 01/11] imx: ventana: remove USB_KEYBOARD support

For some time now having USB_KEYBOARD support has caused usb to be initialized on boot. To allow for a quicker bootup we don't want this for Ventana and don't really need USB keyboard support so remove it.

[PATCH 0/9] Add support for imx8mm-venice-gw7901 and DSA switch
by Tim Harvey 10 Jul '21

10 Jul '21

The GW7901 is an IMX8M Mini based board with a KSZ9897 switch hanging off the IMX8M FEC. In order to support a fixed-link connection to a U-Boot DSA switch some changes need to be made to the FEC driver. Additionally, in order to support per-port unique MAC addrs for DSA we must introduce a mechanism to put the master device in promiscuous mode. All patches are here including adding the dts for the board as well as a dsa driver and necessary patches to fec/dsa so that it is clear how this fits together.

[PATCH v4] armv8: Handle EL2 Host mode
by Mark Kettenis 10 Jul '21

10 Jul '21

On implementations that support VHE, the layout of the CPTR_EL2 register depends on whether HCR_EL2.E2H is set. If the bit is set, CPTR_EL2 uses the same layout as CPACR_EL1 and can in fact be accessed through that register. In that case, jump to the EL1 code to enable access to the FP/SIMD registers. This allows U-Boot to run on systems that pass control to U-Boot in EL2 with EL2 Host mode enabled such as machines using Apple's M1 SoC.

[PATCH v3 00/20] TI/Cadence: Add Sierra/Torrent SERDES driver
by Kishon Vijay Abraham I 09 Jul '21

09 Jul '21

Patch series adds Sierra and Torrent SERDES driver for the SERDES used in TI's K3 platforms. This SERDES is used by USB3, PCIe and Ethernet. This series is mostly an adaptation of drivers added in upstream Linux kernel. Changes from v2: 1) Re-worked "Handle gracefully NULL pointers" to fix Simons comments 2) Ported the part that allows creating clocks without explicit sub-nodes in DT from the upstream linux kernel. Changes from v1: 1) Fixed string comparison strncmp() to remove "==" 2) Added a test for node name comparison to ignore unit address in test/dm 3) Added better commit message in "drivers: reset: Handle gracefully NULL pointers" Alan Douglas (1): phy: cadence: Add driver for Sierra PHY Aswath Govindraju (7): dt-bindings: phy: Add definitions for additional phy types phy: cadence: Add driver for Torrent SERDES board: ti: j721e: Add support for probing and configuring Torrent serdes on J7200 arm: dts: k3-j7200-main: Add DT node for torrent serdes arm: dts: k3-j7200-common-proc-board: Enable SERDES DT arm: dts: k3-j7200-common-proc-board-u-boot: Add u-boot tags for torrent serdes configs: j7200_evm_a72_defconfig: Add config for torrent serdes and common clock framework Jean-Jacques Hiblot (2): phy: ti: j721e-wiz: Add support for WIZ module present in TI J721E SoC configs: j721e_evm_a72: Enable the drivers required for the USB3 support Kishon Vijay Abraham I (10): dm: core: Add helper to compare node names dm: test: Add test case to check node name ignoring unit address drivers: reset: Handle gracefully NULL pointers dt-bindings: phy: Add defines for AM64 SERDES Wrapper dt-bindings: phy: cadence-torrent: Add defines for refclk driver dt-bindings: ti-serdes-mux: Add defines for AM64 SoC usb: cdns3: cdns3-ti: Fix clk_get_by_name() to get the correct name ARM: dts: k3-j721e: Add the entries required for USB3 support on USB0 env: ti: j721e-evm: Add env variable to power on & reset QSGMII PHY in J7200 EVM configs: j7200_evm_a72: Enhance bootcmd to configure ethernet PHY .../k3-j7200-common-proc-board-u-boot.dtsi | 12 + arch/arm/dts/k3-j7200-common-proc-board.dts | 23 + arch/arm/dts/k3-j7200-main.dtsi | 63 + .../k3-j721e-common-proc-board-u-boot.dtsi | 19 +- board/ti/j721e/evm.c | 34 +- configs/j7200_evm_a72_defconfig | 9 +- configs/j721e_evm_a72_defconfig | 6 + drivers/core/ofnode.c | 13 + drivers/phy/Kconfig | 3 + drivers/phy/Makefile | 2 + drivers/phy/cadence/Kconfig | 11 + drivers/phy/cadence/Makefile | 2 + drivers/phy/cadence/phy-cadence-sierra.c | 757 +++++ drivers/phy/cadence/phy-cadence-torrent.c | 2468 +++++++++++++++++ drivers/phy/ti/Kconfig | 9 + drivers/phy/ti/Makefile | 1 + drivers/phy/ti/phy-j721e-wiz.c | 1154 ++++++++ drivers/reset/reset-uclass.c | 35 +- drivers/usb/cdns3/cdns3-ti.c | 2 +- include/configs/j721e_evm.h | 16 +- include/dm/ofnode.h | 10 + include/dt-bindings/mux/ti-serdes.h | 5 + include/dt-bindings/phy/phy-cadence.h | 20 + include/dt-bindings/phy/phy-ti.h | 21 + include/dt-bindings/phy/phy.h | 1 + test/dm/core.c | 14 + 26 files changed, 4700 insertions(+), 10 deletions(-) create mode 100644 drivers/phy/cadence/Kconfig create mode 100644 drivers/phy/cadence/Makefile create mode 100644 drivers/phy/cadence/phy-cadence-sierra.c create mode 100644 drivers/phy/cadence/phy-cadence-torrent.c create mode 100644 drivers/phy/ti/Kconfig create mode 100644 drivers/phy/ti/Makefile create mode 100644 drivers/phy/ti/phy-j721e-wiz.c create mode 100644 include/dt-bindings/phy/phy-cadence.h create mode 100644 include/dt-bindings/phy/phy-ti.h -- 2.17.1
