[PATCH v4 0/5] Implement fastboot multiresponce
by Svyatoslav Ryhel 05 Dec '23

05 Dec '23

Currently u-boot fastboot can only send one message back to host, so if there is a need to print more than one line messages must be kept sending until all the required data is obtained. This behavior can be adjusted using multiresponce ability (getting multiple lines of response) proposed in this patch set. Implementation of multiresponce leads to ability to dump content of console buffer which, with use of "oem run", allows to entirely avoid need in UART. --- Changes from v3: - adjust membuff_readline behavior with overflow Changes from v2: - fix missing function calls if CONFIG_CONSOLE_RECORD is not enabled Changes from v1: - changed variables to static - fixed multiresponce for udp - documented use of "MORE" - converted #if to if (...) --- Ion Agorria (5): fastboot: multiresponse support fastboot: implement "getvar all" common: console: introduce overflow and isempty calls lib: membuff: fix readline not returning line in case of overflow fastboot: add oem console command support common/console.c | 15 ++++-- doc/android/fastboot-protocol.rst | 3 ++ doc/android/fastboot.rst | 1 + drivers/fastboot/Kconfig | 7 +++ drivers/fastboot/fb_command.c | 52 +++++++++++++++++++++ drivers/fastboot/fb_getvar.c | 77 +++++++++++++++++++++++++------ drivers/usb/gadget/f_fastboot.c | 29 ++++++++++++ include/console.h | 26 +++++++++++ include/fastboot-internal.h | 7 +++ include/fastboot.h | 19 ++++++++ lib/membuff.c | 10 ---- net/fastboot_udp.c | 29 +++++++++--- test/ut.c | 9 ++-- 13 files changed, 247 insertions(+), 37 deletions(-) -- 2.40.1

[PATCH 0/2] serial: msm-geni: rework oversampling and fix clk API bug
by Caleb Connolly 04 Dec '23

04 Dec '23

These patches improve GENI UART support during init by implementing the parent property read directly rather than via a misc device, and fixing the error path when the clock can't be found. In my testing, the first few lines of UART output on platforms with non-default oversampling values is often garbled, this is because the parent misc device hasn't yet probed and so the clock rate is incorrect. It is simpler to just access the geni-se parent device directly rather than via a misc device, especially as we only need to read a single register for now. Additionally, this series makes it a hard requirement that the GENI UART node is a child of the generic geni-se controller. This allows us to print a useful error if DTS is incorrect rather than attempting to continue without reading the oversampling value could result in a lot of confusion during platform bringup. --- Caleb Connolly (2): serial: msm-geni: don't rely on parent misc device serial: msm-geni: handle devm_clk_get() errors drivers/misc/Kconfig | 7 ------- drivers/misc/Makefile | 1 - drivers/misc/qcom-geni-se.c | 41 ---------------------------------------- drivers/serial/Kconfig | 2 -- drivers/serial/serial_msm_geni.c | 40 ++++++++++++++++++++++++++------------- 5 files changed, 27 insertions(+), 64 deletions(-) --- base-commit: f3fc930d775ef5c1b7b74b1427491a17680e66ae // Caleb (they/them)

[PATCH 0/4] Support StarFive Watchdog driver
by Chanho Park 04 Dec '23

04 Dec '23

This patchset adds to support StarFive Watchdog driver which is based on Linux kernel's starfive-wdt driver. Actually, the original driver supports both JH7100 and JH7110 with variant coding but this removes the JH7100 part of codes because JH7100 isn't supported in u-boot yet. However, this patch tries to keep the variant coding style for future work of JH7100 and have a consistency with the Linux driver.

[PATCH 0/5] video: Improve syncing performance with cyclic
by Simon Glass 04 Dec '23

04 Dec '23

Now that U-Boot has a background-processing feature, it is possible to reduce the amount of 'foreground' syncing of the display. At present this happens quite often. Foreground syncing blocks all other processing, sometimes for 10ms or more. When pasting commands into U-Boot over the UART, this typically result in characters being dropped. For example, on rpi_4 it isn't possible to paste in more than 35 characters before things fail. This makes updating the environment or entering long commands very painful over the console, since text must be pasted in chunks, or the vidconsole device must be dropped from stdout. This series introduces background syncing, enabled by default for boards which use video. The sync rates for foreground and background are configurable. With this series it is possible to paste in any amount of text to the command line. Some sandbox-specific work-arounds can now be removed and sandbox video (./u-boot -Dl) is significantly more responsive. This obviously increases code size, since it enables a subsystem not normally used by default. However it only applies to boards which have VIDEO enabled, which are presumably less worried about memory space since the video code is fairly large. Also it is possible to disable CMD_CYCLIC and reduce the groth to: aarch64: (for 1/1 boards) all +1081.0 rodata +65.0 text +1016.0 arm: (for 1/1 boards) all +945.0 rodata +65.0 text +880.0 Without that, the increase doubles. It is of course possible to disable CYCLIC and still use VIDEO but this reverts to the current behaviour Simon Glass (5): cyclic: Disable in SPL builds video: Move last_sync to private data video: Use cyclic to handle video sync sandbox: Increase cyclic CPU-time limit sandbox: Drop video-sync in serial driver common/Kconfig | 1 + common/Makefile | 2 +- drivers/serial/sandbox.c | 2 -- drivers/video/Kconfig | 30 +++++++++++++++++++++ drivers/video/video-uclass.c | 52 +++++++++++++++++++++++++++++------- include/cyclic.h | 6 +++-- include/video.h | 2 ++ 7 files changed, 81 insertions(+), 14 deletions(-) -- 2.43.0.rc0.421.g78406f8d94-goog

efi: Set Variable Runtime implementation
by Shantur Rathore 04 Dec '23

04 Dec '23

Hi Heinrich, I am trying to work out how to enable the SetVariableRT service in U-Boot and came across your patch [1] which initially had the SetVariable RT service enabled in EFI but in the final patch this was removed. I am hoping to implement it on top of the SPI Flash EFI store [2] to be able to set Boot order and boot items from Linux the UEFI way. Can I pick your brain on why it was dropped in the patch? Is there any limitation in SetVariableRT service ? Kind regards, Shantur [1] : https://patches.linaro.org/project/u-boot/patch/20200331060541.4212-1-xypro… [2] : https://patchwork.ozlabs.org/project/uboot/list/?series=383699

[PATCH 0/3] sunxi: add OrangePi Zero 3 board support
by Andre Przywara 04 Dec '23

04 Dec '23

The OrangePi Zero 3 is a small development board featuring the Allwinner H618 SoC. Compared to its predecessor OrangePi Zero 2, the new board uses LPDDR4 DRAM instead of DDR3 DRAM, and an X-Powers AXP313 PMIC instead of the AXP305. U-Boot gained support for both LPDDR4 DRAM and the new PMIC just recently, so add a user for those features by adding a defconfig for the new board. To make this work, patch 1/3 introduces support for zBIT SPI NOR flash chip, and patch 2/3 removes the default AXP305 PMIC selection when compiling for H616 SoCs. Patch 3/3 then adds the defconfig. The DT was already synced from the Linux kernel repo a few weeks ago.
