[PATCH 1/1] efi_loader: simplify 'printenv -e'
by Heinrich Schuchardt 15 Jul '20

15 Jul '20

Currently default output of 'printenv -e' is restricted to variables with GUID EFI_GLOBAL_VARIABLE. This excludes db and dbx. As the number of variables is small there is no need for this restriction. If no GUID is provided, print all matching variables irrespective of GUID. Always show the numeric value of the GUID. If the GUID provided to 'setenv -e' is invalid, return CMD_RET_USAGE.

[PATCH 0/6] Improve USB Keyboard support for all rpi boards
by Jason Wessel 15 Jul '20

15 Jul '20

Prior to this patch set, I had just a small number of USB keyboards function properly with the Rasbpberry Pi boards. Nearly every composite USB keyboard/mouse I had access to including the Raritan IP/KVM devices would not initialize properly. At this point I have tested all generations of the Raspberry Pi boards (0-4) and the USB keyboards I use day to day are working properly. For the RPi4, I tested against the rpi-master branch which now has the required USB patches, all the other boards were tested against the master branch. v1: - Testing completed against all generations of raspberry pi boards - check patch warnings add errors have been fixed rfc v3: - Add in patch 6 - Finally got the GearHead keyboard + mouse composite USB device working rfc v2: - Minor cleanups to patches 1-3 based on prior review - Patch 4 & 5 are new to fix various xhchi crashes while having additional devices plugged in along with booting off the usb port. The nonblocking mode turned out to be somewhat complex. rfc v1: The original purpose of the patch set was to fix problems with the USB keyboard support with the rpi4. The generic xhci code lacks a non blocking call to read an event. This causes major problems for the sleep function as well as for ethernet downloads where a keyboard poll for interrupting the download blocks for 5 seconds. ---------------------------------------------------------------- Jason Wessel (6): xhci: Add polling support for USB keyboards usb_kbd: succeed even if no interrupt is pending common/usb.c: Work around keyboard reporting "USB device not accepting new address" xhci-ring.c: Add the poll_pend state to properly abort transactions xhci-ring: Fix crash when issuing "usb reset" usb.c: Add a retry in the usb_prepare_device() common/usb.c | 16 +++++++++++++--- common/usb_kbd.c | 4 +++- drivers/usb/host/xhci-ring.c | 123 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++--------------------------- drivers/usb/host/xhci.c | 11 ++++++----- include/usb/xhci.h | 5 +++-- 5 files changed, 121 insertions(+), 38 deletions(-)

[RFC PATCH 0/3] DM_MDIO for fsl_tsec driver

rockchip RK3399 emmc booting
by Belisko Marek 15 Jul '20

15 Jul '20

Hi, I'm trying to run mainline on a custom rk3399 board which boots from eMMC only. Currently I'm using Rockchip SDK which can build an image for the whole system) and then flash it to emmc using (AFAIU using dfu in u-boot). Does anyone have experience with mainline running on rk3399 and have the same functionality? Or is there another way to flash images to eMMC?

15 Jul '20

This series is split off from the original ACPI series and renumbered to version 1. It includes functions for generating more ACPI constructs as well as I2C, GPIO and sound support. There are also quite a few patches related to getting coral to work correctly with ACPI. Changes in v2: - Rename binman_entry_find_() - Fix 'Gailed' typo - Rename parameter from 'name' to 'scope' - Add a comment pointing to the PCI spec - Move this patch before the audio-codec drivers - Use BIT() for the SPEAKER enum Add a comment about only x86 boards supporting NHLT Add a comment about only x86 boards supporting NHLT -

[PATCH 0/3] lib: fdt: Remove two functions from fdtdec.c
by Michal Simek 15 Jul '20

15 Jul '20

Hi, Simon has asked in thread https://lists.denx.de/pipermail/u-boot/2020-July/419489.html to move to ofnode functions. And by looking at it I found that fdtdec_setup_memory/banksize_fdt() can be removed to simplify conversion to ofnode. Renesas low level code is simply to convert to previous functions that's why there is no reason to keep wrappers around. Thanks, Michal Michal Simek (3): ARM: rmobile: Switch back to fdtdec_setup_memory/banksize_fdt() Revert "lib: fdt: Split fdtdec_setup_memory_banksize()" Revert "lib: fdt: Split fdtdec_setup_mem_size_base()" board/renesas/rcar-common/common.c | 4 +-- include/fdtdec.h | 39 ------------------------------ lib/fdtdec.c | 29 +++++++--------------- 3 files changed, 11 insertions(+), 61 deletions(-) -- 2.27.0

[PATCH v4 0/2] add optee support for broadcom NS3 soc
by Rayagonda Kokatanur 15 Jul '20

15 Jul '20

This is fourth patch set series prepared on top of third patch set ("add FIT image support for broadcom NS3 soc"). This patch adds optee support. Changes from v3: -Address review comments from Simon, Rearrange code and remove while loop, Add comments for function. Changes from v2: -Address review comments from Simon, Remove own return code and use standard error code. Take out common lines from different functions and move them into common static function. Remove include <common.h> as its not required. Move functions with printf from header file into c file. -Address slef review comments, Remove optee dt node as this file is no longer in sync with linux. Changes from v1: -Address review comments from Thomas Fitzsimmons, Expand the bnxt full form. -Address review comments from Simon Glass, Move c file from board/broadcom/bcmns3/chimp_optee.c to drivers/tee/broadcom, Move header file from include/brcm/chimp.h to include/broadcom/chimp.h Rayagonda Kokatanur (1): configs: ns3: enable tee and optee driver Vikas Gupta (1): drivers: tee: broadcom: add optee based bnxt fw load driver configs/bcm_ns3_defconfig | 5 +- drivers/tee/Kconfig | 1 + drivers/tee/Makefile | 1 + drivers/tee/broadcom/Kconfig | 7 ++ drivers/tee/broadcom/Makefile | 3 + drivers/tee/broadcom/chimp_optee.c | 180 +++++++++++++++++++++++++++++ include/broadcom/chimp.h | 43 +++++++ 7 files changed, 239 insertions(+), 1 deletion(-) create mode 100644 drivers/tee/broadcom/Kconfig create mode 100644 drivers/tee/broadcom/Makefile create mode 100644 drivers/tee/broadcom/chimp_optee.c create mode 100644 include/broadcom/chimp.h -- 2.17.1
