[PATCH 0/5] Introduce DSA Ethernet switch class and Felix driver
by Claudiu Manoil 25 Jan '21

25 Jan '21

DSA stands for Distributed Switch Architecture and it is a subsystem introduced in the Linux kernel to support switches that: - have an Ethernet link up to the CPU - use some form of tagging to identify the source/destination port for Rx/Tx - may be cascaded in tree-like structures. DSA is described in depth here: https://www.kernel.org/doc/Documentation/networking/dsa/dsa.txt This patch set introduces a DSA class in U-Boot to support drivers of DSA switches. DSA drivers have to implement the following ops: - enable/disable of switch ports, - insert a tag in frames being transmitted, used by the switch to select the egress port, - parse a tag in frames being received, used for Rx traffic. DSA class code deals with presentation of switch ports as Ethernet interfaces, deals with the master Ethernet device for I/O and helps with parsing of the DT assuming the structure follows the DSA kernel binding. Support for switch cascading is not included yet. In the sandbox environment, the DSA sandbox driver, the switch ports and master eth interface look like this: => dm tree Class Index Probed Driver Name ----------------------------------------------------------- [...] eth 4 [ + ] eth_sandbox |-- dsa-test-eth dsa 0 [ + ] dsa_sandbox |-- dsa-test eth 5 [ + ] dsa-port | |-- lan0 eth 6 [ + ] dsa-port | `-- lan1 => setenv ethact lan1 => ping 1.2.3.5 Using lan1 device host 1.2.3.5 is alive => This patch set also introduces a driver for the Ethernet switch integrated into NXP LS1028A, called Felix. The switch has 4 front panel ports, I/O to/from it is done though an ENETC Ethernet interface and meta-data is carried between the switch and the driver though an additional header pre-pended to the original frame. Network commands like tftp can be used on these front panel ports. The ports are disabled unless used so they do not cause issues on network topologies that include loops. Felix as seen on LS1028A RDB: => dm tree Class Index Probed Driver Name ----------------------------------------------------------- [...] dsa 0 [ + ] felix-switch | |-- felix-switch eth 4 [ + ] dsa-port | | |-- swp0 eth 5 [ + ] dsa-port | | |-- swp1 eth 6 [ + ] dsa-port | | |-- swp2 eth 7 [ + ] dsa-port | | `-- swp3 => mdio list [...] 10 - Vitesse VSC8514 <--> swp0 11 - Vitesse VSC8514 <--> swp1 12 - Vitesse VSC8514 <--> swp2 13 - Vitesse VSC8514 <--> swp3 NOTE: This patchset is a major rework of the dsa-class code since the last submission from May 5th: https://patchwork.ozlabs.org/project/uboot/cover/1588700588-8587-1-git-send… The basic concepts and data path operation (tagging) in the DSA class code remain the same as in the initial patchset from Alex, however the external API has been changed significantly (simplified), the driver model integration has been improved to the point that the DSA class code no longer needs to allocate extra memory internally (via malloc), reduced memory footprint, internal state data moved from the external API and internalized, cleaner external API, internal code reworked, completly reworked DSA sandbox driver and unit tests for better coverage and to integrate better with the eth sandbox driver and tests, etc. The DSA class code is now ported on top of the latest u-boot master branch (obviously), and I tested it thoroughly with the sandbox driver and unit tests. The felix driver has been tested with an older uboot, since there are some issues booting the latest upstream uboot on a LS1028A RDB board. Note that the felix driver itself didn't change since the last submission, except for the DSA API function calls.

[patch v3 0/9] rk3399 (Pinebook pro) EDP support
by Arnaud Patard 25 Jan '21

25 Jan '21

This patchset add support for the rk3399 eDP. It has been tested on the pinebook pro and Google Kevin chromeos devices. The changes have been written by studying the linux code, since I didn't find any manual for theses part of the RK3399 SoC. On the linux kernel side, on recent kernels, it needs commit "pwm: rockchip: Keep enabled PWMs running while probing" otherwise the pinebook pro will freeze when probing the display. Changes since v2: - Respect alphabetical order in uboot.dtsi in patch "rk3399-pinebook-pro-u-boot.dtsi: Enable edp" - drop "configs/pinebook-pro-rk3399_defconfig: enable SYS_USB_EVENT_POLL_VIA_INT_QUEUE" (pbp_defconfig_usb_poll.patch) patch, since the same change has been merged with change https://gitlab.denx.de/u-boot/custodians/u-boot-rockchip/-/commit/b197c934b… - change patch subjects. Changes since v1: - Add reset support for the VOP and eDP. This was needed and it appears to also solve the issue with warm reset. - Fix a debug string in the vop driver - Drop the patch "drivers/video/rockchip/rk_edp.c: Change clock rate". - Address various comments

[PATCH 0/3] Fixes for SPI-NAND issues on LS1088A
by Mathew McBride 25 Jan '21

25 Jan '21

This patchset resolves issues seen when using SPI-NAND with the LS1088A's qspi controller. The main issue seen is data corruption when reading SPI-NAND, due to a controller quirk not being applied. Using the same settings as the LS2088A (the bigger brother of LS1088A) solves this issue. In the course of debugging the above issue, it was found that the fsl_qspi driver was not correctly reporting the operation width (single/dual/quad) configured for the device in DTS. (e.g I configured my device for single-lane reads only but quad operations were being issued) A fix for this issue is already present in Linux and can be adapted for U-Boot, providing a missing export for spi_mem_default_supports_op is added. Mathew McBride (3): mem: spi-mem: define spi_mem_default_supports_op spi: fsl_qspi: Ensure width is respected in spi-mem operations spi: fsl_qspi: apply the same settings for LS1088 as LS208x drivers/spi/fsl_qspi.c | 12 ++---------- include/spi-mem.h | 10 ++++++++++ 2 files changed, 12 insertions(+), 10 deletions(-) -- 2.30.0

[PATCH] mmc: mmc_spi: Do not drop first RX byte after CMD TX
by Jiaxun Yang 25 Jan '21

25 Jan '21

As per MMC SPI specification, R1 response could just follow the CMD TX. Currently we drop the first RX byte after the CMD TX. It is harmless in realworld as MMC card need time to take command action so the first resp will always be R1b(busy). However in QEMU ssi-sd emulation, R1 resp is just followed after, so R1 will be dropped here.

[RFC PATCH] arm: EFI: Disallow EFI bootmgr when providing PSCI
by Andre Przywara 25 Jan '21

25 Jan '21

When "bootefi bootmgr" is run, it switches the CPU into non-secure state. This breaks platforms like 32-bit Allwinner boards that rely on running in secure state until late in the process, when they install the PSCI handler in secure memory and drop into non-secure state. They hang just before entering the kernel, after the "Starting the kernel" message. Commit f3866909e350 ("distro_bootcmd: call EFI bootmgr even without having /EFI/boot") changed the order of EFI probing, so the EFI bootmgr is now *always* run, resulting in the default distro boot commands now *always* failing, even in the total absence of any UEFI directories or boot files. So use the newly added build option to disable the EFI bootmgr, which makes those boards boot again using the distro boot commands. Explicitly calling "bootefi bootmgr" still breaks the boot, though. Signed-off-by: Andre Przywara <andre.przywara(a)arm.com> Reported-by: Jernej Skrabec <jernej.skrabec(a)siol.net> --- Hi, the above is the result of my analysis, happy to stand corrected in case I missed something. I know that this is not a proper solution, but it's an effective stop-gap measure to fix all those boards. It looks like a proper solution would either be: - Let the EFI bootmgr run in the current security state. - Install the PSCI handlers early in U-Boot. Both solutions sound rather involved, so probably require more time. But we need to fix this breakage now.
