[U-Boot] dwc2 USB host initialization issue
by Bogdan Harjoc 29 Aug '18

29 Aug '18

I am trying to initialize a dwc2 usb otg host using the u-boot dwc2 driver in u-boot and barebox and am trying to get past the port power-up step. The controller is activated successfully once the Linux kernel boots up and the mass storage devices are accessible, but in u-boot and barebox it seems to not receive the USB_PORT_STAT_C_CONNECTION nor the USB_PORT_STAT_C_ENABLE port change status. In the bootloader, usb_get_port_status returns 0x510 (i.e. HIGH_SPEED | POWER | RESET), while under linux the status after powering up the port is 0x101 (i.e. POWER | CONNECTION) and the linux usb core then properly brings up the port. I looked at the submitted usb requests, and didn't see any relevant difference (bootloader vs linux). All I could see from the debug output is that PwrOn2PwrGood time and HubContrCurrent are both zero in barebox and nonzero in linux. Could the cause be the fact that in the bootloader the port comes up with HIGH_SPEED status ? Can I disable this flag during hub initialization ? Or is there another probable cause for this ? Regards, Bogdan

[U-Boot] [PATCH] imx: imx6ull: fix pinmux input_val for uart5 rx pin
by Heiko Schocher 29 Aug '18

29 Aug '18

just try to bring up an imx6ull board with console on uart5 and found, that input_val for pin MX6UL_PAD_UART5_RX_DATA__UART5_DCE_RX is 7 and not 5 on imx6ull. With this patch rx works now.

[U-Boot] [PATCH v2 0/3] RK3399: Add support for Ficus board
by Ezequiel Garcia 29 Aug '18

29 Aug '18

Add support for a new RK3399-based board. The RK3399 Ficus board is an Enterprise Edition board manufactured by Vamrs Ltd., based on the Rockchip RK3399 SoC. While here, we extend the evb_rk3399/README document with instructions for SD/MMC boot. The devicetree file for this board has been already merged in Linux maintainer's tree: https://kernel.googlesource.com/pub/scm/linux/kernel/git/mmind/linux-rockch… Changes from v1: * Drop CONFIG_ROCKCHIP_USB2_PHY which wasn't appropriate for this board, and also it was breaking the build. * Tested on travis-ci.org.

[U-Boot] [PATCH 00/10] AVB using OP-TEE
by Jens Wiklander 28 Aug '18

28 Aug '18

Hi, This adds support for storing AVB rollback indexes in the RPMB partition. The RPMB partition (content and key) is managed by OP-TEE (https://www.op-tee.org/) which is a secure OS leveraging ARM TrustZone. The Linux kernel can already support OP-TEE with reading and updating rollback indexes in the RPMB partition, the catch is that this is needed before the kernel has booted. The design here is the same as what is in the Linux kernel, with the exception that the user space daemon tee-supplicant is integrated in the OP-TEE driver here (drivers/tee/optee/supplicant.c) instead. A new uclass (UCLASS_TEE) is introduced to provide an abstraction for interfacing with a Trusted Execution Environment (TEE). There's also the OP-TEE driver using UCLASS_TEE for registration. A Trusted Application (TA) interface is added to be used by the AVB verify functions which are updated accordingly. The TA is managed by OP-TEE and is executed in a secure TrustZone protected environment. The header files drivers/tee/optee/optee_{msg,msg_supplicant,smc}.h and include/tee/optee_ta_avb.h are copied from https://github.com/OP-TEE/optee_os/tree/master more or less unmodified. They may need to be updated from time to time in order to support new features. In MMC there's a new function, mmc_rpmb_route_frames(), which as the name suggests is used to route RPMB frames to/from the MMC. This saves OP-TEE from implementing an MMC driver which would need to share resources with its counterpart here in U-boot. This was tested on a Hikey (Kirin 620) board. I've added myself as maintainer of the TEE stuff.
