USB3 XHCI crashing with USB 3 hub on Octeon

Hi all, While backporting the latest USB support in U-Boot to support USB 3 hubs I decided to try the latest U-Boot for Octeon which should contain everything. When I start USB, however, with a USB 3 thumb drive plugged into a USB 3 hub, I am seeing a crash. I have enabled all of the debugging support for usb.c, usb_hub.c, xhci.c, xhci-ring.c and xhci_mem.c In my backported code which is a bit hacked up due to the lack of DT support, I am seeing it fail when it attempts to set the hub depth. Note that everything works fine with a USB 2 hub. I was hoping to compare the stock U- Boot with my hacked up code to track down the issue. -Aaron Here are the logs: => usb start starting USB...

[PATCH 00/10] Add support for extension boards detection and DT overlays application
by Kory Maincent 23 Feb '21

23 Feb '21

This series of patches aims at proposing a generic U-Boot mechanism to detect extension boards connected to the HW platform, and apply the appropriate Device Tree overlays depending on the detected extension boards. Indeed, numerous popular platforms, such as the BeagleBone or the RaspberryPi, feature some kind of extension board mechanism. These extension boards are often discoverable through some kind of EEPROM (connected on I2C, 1-wire, etc.) and require Device Tree overlays to be applied at the U-Boot level to provide a complete HW description to the Linux kernel. However, currently this logic is usually implemented ad-hoc in downstream forks of U-Boot. This series proposes to bring a HW-agnostic and generic solution to this problem to upstream U-Boot. The series shows that it is generic enough by implementing its usage for 2 different families of HW platforms and expansion boards: - The BeagleBone Black and BeagleBone AI, that use extension boards where the EEPROM describing the extension boards is connected over I2C. - The CHIP, that uses extension boards where the EEPROM describing the extension boards is connected over 1-wire. The patch series implements a new command called "extension", with two sub-commands: - "extension scan" to detect available extension boards - "extension list" will simply list the detected extension boards - "extension apply" will allow to apply the Device Tree overlays corresponding to one extension board or to all expansion boards Note that the name "extension" has been chosen to not refer to any particular board-specific terminology for extension boards ("cape" for BeagleBone, "DIP" for CHIP, "hat" for RaspberryPi, etc.). However, we welcome suggestions of other names and are definitely willing to use a different naming. The "extension apply" command requires two environment variables to be defined so that it knows how to apply DT overlays. This is described in more details in PATCH 1. This generic code requires board-specific code for the detection and enumeration of extension boards. This is simply implemented in the form of a board-specific extension_board_scan() function, which fills in a list of detected extension boards. In detail: - PATCH 1 move fdt_valid function to fdt_support file - PATCH 2 implements the generic command and logic - PATCH 3 implements the python test for the "extension" command - PATCH 4 implements the board-specific code for the BeagleBone platforms - PATCH 5 enables the mechanism for the BeagleBone AI - PATCH 6 to 8 enable the mechanism for the CHIP - PATCH 9 and 10 enable the mechanism for the BeagleBone Black Thanks in advance for your review and feedback Kory Maincent (10): fdt_support: move fdt_valid from cmd_fdt.c to fdt_support.c cmd: add support for a new "extension" command pytest: add sandbox test for "extension" command ti/common: add support for extension_scan_board function am57xx: add support for cape detect functionality arm: dts: sun5i: enable one-wire on the CHIP arm: mach-sunxi: add CHIP board target sun5i: add support for DIP detection to CHIP board arm: am335x: add support for i2c2 bus am335x: add support for cape detect functionality arch/Kconfig | 2 + arch/arm/dts/sun5i-r8-chip.dts | 6 + arch/arm/mach-omap2/am33xx/Kconfig | 1 + arch/arm/mach-omap2/am33xx/clock_am33xx.c | 1 + arch/arm/mach-omap2/omap5/Kconfig | 1 + arch/arm/mach-sunxi/Kconfig | 16 +++ arch/sandbox/dts/Makefile | 1 + arch/sandbox/dts/overlay0.dts | 9 ++ arch/sandbox/dts/overlay1.dts | 9 ++ board/sandbox/sandbox.c | 23 +++ board/sunxi/Makefile | 1 + board/sunxi/chip.c | 104 ++++++++++++++ board/ti/am335x/board.c | 3 + board/ti/am335x/board.h | 1 + board/ti/am335x/mux.c | 15 ++ board/ti/am57xx/board.c | 1 + board/ti/common/Kconfig | 3 + board/ti/common/Makefile | 1 + board/ti/common/cape_detect.c | 96 +++++++++++++ board/ti/common/cape_detect.h | 28 ++++ cmd/Kconfig | 12 ++ cmd/Makefile | 1 + cmd/extension_board.c | 167 ++++++++++++++++++++++ cmd/fdt.c | 49 ------- common/fdt_support.c | 46 ++++++ configs/CHIP_defconfig | 1 + doc/README.extension | 80 +++++++++++ include/configs/am335x_evm.h | 2 + include/configs/am57xx_evm.h | 2 + include/extension_board.h | 31 ++++ include/fdt_support.h | 2 + test/py/tests/test_extension.py | 52 +++++++ 32 files changed, 718 insertions(+), 49 deletions(-) create mode 100644 arch/sandbox/dts/overlay0.dts create mode 100644 arch/sandbox/dts/overlay1.dts create mode 100644 board/sunxi/chip.c create mode 100644 board/ti/common/cape_detect.c create mode 100644 board/ti/common/cape_detect.h create mode 100644 cmd/extension_board.c create mode 100644 doc/README.extension create mode 100644 include/extension_board.h create mode 100644 test/py/tests/test_extension.py -- 2.17.1

[PATCH] spi: zynqmp_gqspi: fix set_speed bug on multiple runs
by Brandon Maier 23 Feb '21

23 Feb '21

If zynqmp_qspi_set_speed() is called multiple times with the same speed, then on the second call it will skip recalculating the baud_rate_val as it assumes the speed is already configured correctly. But it will still write the baud_rate_val to the configuration register and call zynqmp_gqspi_set_tapdelay(). Because it skipped recalculating the baud_rate_val, it will use the initial value of 0 . This causes the driver to run at maximum speed which for many spi flashes is too fast and causes data corruption. Instead only write out a new baud_rate_val if we have calculated the correct baud_rate_val. This opens up another issue with the "if (speed == 0)", we don't save off the new plat->speed_hz value when setting the baud rate on the speed=0 path. Instead mimic what the Linux zynqmp gqspi driver does, and have speed==0 just use the same calculation as a normal speed. That will cause the baud_rate_val to use the slowest speed possible, which is the safest option.

[PATCH v2 00/38] ppc: qemu: Convert qemu-ppce500 to driver model and enable additional driver support
by Bin Meng 23 Feb '21

23 Feb '21

At present when building qemu-ppce500 the following warnings are seen: ===================== WARNING ====================== This board does not use CONFIG_DM. CONFIG_DM will be compulsory starting with the v2020.01 release. Failure to update may result in board removal. UPD include/generated/timestamp_autogenerated.h See doc/driver-model/migration.rst for more info. ==================================================== ===================== WARNING ====================== This board does not use CONFIG_DM_PCI Please update the board to use CONFIG_DM_PCI before the v2019.07 release. Failure to update by the deadline may result in board removal. See doc/driver-model/migration.rst for more info. ==================================================== ===================== WARNING ====================== This board does not use CONFIG_DM_ETH (Driver Model for Ethernet drivers). Please update the board to use CONFIG_DM_ETH before the v2020.07 release. Failure to update by the deadline may result in board removal. See doc/driver-model/migration.rst for more info. ==================================================== The conversion of qemu-ppce500 board to driver model is long overdue. When testing the exisitng qemu-ppce500 support, PCI was found broken. This is caused by 2 separate issues: - One issue was caused by U-Boot: Commit e002474158d1 ("pci: pci-uclass: Dynamically allocate the PCI regions") Patch #1 updated the non-DM fsl_pci_init driver to dynamically allocate the PCI regions, to keep in sync with the pci uclass driver - One issue was caused by QEMU: commit e6b4e5f4795b ("PPC: e500: Move CCSR and MMIO space to upper end of address space") commit cb3778a0455a ("PPC: e500 pci host: Add support for ATMUs") Patch #3-4 fixed this issue to keep in sync with latest QEMU upstream Patch #5-8, #34-36 are minor fixes and clean-ups. Starting from patch#9, these are driver model conversion patches. Patch #11-17 are mainly related to CONFIG_ADDR_MAP, a library to support targets that have non-identity virtual-physical address mappings. A new command 'addrmap' is introduced to aid debugging, and a fix to arch/powerpc/asm/include/io.h is made to correct the usage of CONFIG_ADDR_MAP as it can only be used in the post- relocation phase. Also the initialization of this library is moved a bit earlier in the post-relocation phase otherwise device drivers won't work. Patch #19-21 are 85xx PCI driver fixes. It adds support to controller register physical address beyond 32-bit, as well as support to 64-bit bus and cpu address as current upstream QEMU uses 64-bit cpu address. Starting from patch#24, these are additional driver support patches. Patch #24, #26 are minor fix to the 'virtio' command and BLK driver dependency. Patch #25 enables the VirtIO NET support as by default a VirtIO standard PCI networking device is connected as an ethernet interface at PCI address 0.1.0. Patch #27 enables the VirtIO BLK driver support. Patch #28-30 enables the GPIO support. Patch #31-32 enables poweroff via GPIO. Patch #33 enables RTC over the I2C bus. Patch #37 moves the qemu-ppce500 boards codes to board/emulation as that is the place for other QEMU targets like x86, arm, riscv. Patch #38 adds a reST document to describe how to build and run U-Boot for the QEMU ppce500 machine. I hope we can make this series to U-Boot v2021.04 release. This series is available at u-boot-x86/qemu-ppc for testing. This cover letter is cc'ed to QEMU mailing list for a heads-up. A future patch will be sent to QEMU mailing list to bring its in-tree U-Boot source codes up-to-date. Changes in v2: - drop the revert patch of commit e002474158d1 - new patch: pci: fsl_pci_init: Dynamically allocate the PCI regions - add more details in the commit message, and put some comments in the codes to explain why - add doc/usage/addrmap.rst - new patch: test: cmd: Add a basic test for 'addrmap' command - new patch: virtio: Fix VirtIO BLK driver dependency - new patch: ppc: qemu: Enable VirtIO BLK support - new patch: ppc: mpc85xx: Add 'gpibe' register to 'struct ccsr_gpio' - new patch: gpio: mpc8xxx: Support controller register physical address beyond 32-bit - new patch: ppc: qemu: Enable GPIO support - new patch: dm: sysreset: Add a Kconfig option for the 'reset' command - new patch: ppc: qemu: Enable support for power off via GPIO - new patch: ppc: qemu: Enable RTC support via I2C - new patch: ppc: qemu: Delete the temporary FDT virtual-physical mapping after U-Boot is relocated - new patch: ppc: qemu: Drop a custom env variable 'fdt_addr_r' - new patch: ppc: qemu: Drop fixed_sdram() - add descriptions for VirtIO BLK, RTC and power off Bin Meng (38): pci: fsl_pci_init: Dynamically allocate the PCI regions ppc: qemu: Update MAINTAINERS for correct email address common: fdt_support: Support special case of PCI address in fdt_read_prop() ppc: qemu: Support non-identity PCI bus address ppc: qemu: Fix CONFIG_SYS_PCI_MAP_END ppc: mpc85xx: Wrap LAW related codes with CONFIG_FSL_LAW ppc: qemu: Drop init_laws() and print_laws() ppc: qemu: Drop board_early_init_f() ppc: qemu: Enable OF_CONTROL ppc: qemu: Enable driver model include: Remove extern from addr_map.h lib: addr_map: Move address_map[] type to the header file cmd: Add a command to display the address map test: cmd: Add a basic test for 'addrmap' command lib: kconfig: Mention CONFIG_ADDR_MAP limitation in the help ppc: io.h: Use addrmap_ translation APIs only in post-relocation phase common: Move initr_addr_map() to a bit earlier ppc: qemu: Switch over to use DM serial pci: mpc85xx: Wrap LAW programming with CONFIG_FSL_LAW pci: mpc85xx: Support controller register physical address beyond 32-bit pci: mpc85xx: Support 64-bit bus and cpu address ppc: qemu: Switch over to use DM ETH and PCI ppc: qemu: Drop CONFIG_OF_BOARD_SETUP cmd: Fix virtio command dependency ppc: qemu: Enable VirtIO NET support virtio: Fix VirtIO BLK driver dependency ppc: qemu: Enable VirtIO BLK support ppc: mpc85xx: Add 'gpibe' register to 'struct ccsr_gpio' gpio: mpc8xxx: Support controller register physical address beyond 32-bit ppc: qemu: Enable GPIO support dm: sysreset: Add a Kconfig option for the 'reset' command ppc: qemu: Enable support for power off via GPIO ppc: qemu: Enable RTC support via I2C ppc: qemu: Delete the temporary FDT virtual-physical mapping after U-Boot is relocated ppc: qemu: Drop a custom env variable 'fdt_addr_r' ppc: qemu: Drop fixed_sdram() ppc: qemu: Move board directory from board/freescale to board/emulation doc: Add a reST document for qemu-ppce500 arch/powerpc/cpu/mpc85xx/Kconfig | 2 +- arch/powerpc/cpu/mpc85xx/cpu.c | 2 + arch/powerpc/cpu/mpc85xx/cpu_init_early.c | 2 + arch/powerpc/include/asm/arch-mpc85xx/gpio.h | 2 +- arch/powerpc/include/asm/immap_85xx.h | 1 + arch/powerpc/include/asm/io.h | 15 +- .../{freescale => emulation}/qemu-ppce500/Kconfig | 2 +- board/emulation/qemu-ppce500/MAINTAINERS | 7 + .../{freescale => emulation}/qemu-ppce500/Makefile | 0 .../qemu-ppce500/qemu-ppce500.c | 178 +++++++-------------- board/freescale/qemu-ppce500/MAINTAINERS | 6 - cmd/Kconfig | 8 + cmd/Makefile | 1 + cmd/addrmap.c | 35 ++++ common/board_r.c | 6 +- common/fdt_support.c | 20 ++- configs/qemu-ppce500_defconfig | 27 +++- doc/board/emulation/index.rst | 1 + doc/board/emulation/qemu-ppce500.rst | 88 ++++++++++ doc/usage/addrmap.rst | 41 +++++ doc/usage/index.rst | 1 + drivers/gpio/mpc8xxx_gpio.c | 7 +- drivers/pci/fsl_pci_init.c | 5 + drivers/pci/pci_mpc85xx.c | 25 +-- drivers/sysreset/Kconfig | 6 + drivers/sysreset/sysreset-uclass.c | 2 + drivers/virtio/Kconfig | 1 + include/addr_map.h | 16 +- include/configs/qemu-ppce500.h | 30 +--- include/test/suites.h | 2 + lib/Kconfig | 2 + lib/addr_map.c | 6 +- test/cmd/Makefile | 1 + test/cmd/addrmap.c | 38 +++++ test/cmd_ut.c | 6 + 35 files changed, 397 insertions(+), 195 deletions(-) rename board/{freescale => emulation}/qemu-ppce500/Kconfig (86%) create mode 100644 board/emulation/qemu-ppce500/MAINTAINERS rename board/{freescale => emulation}/qemu-ppce500/Makefile (100%) rename board/{freescale => emulation}/qemu-ppce500/qemu-ppce500.c (65%) delete mode 100644 board/freescale/qemu-ppce500/MAINTAINERS create mode 100644 cmd/addrmap.c create mode 100644 doc/board/emulation/qemu-ppce500.rst create mode 100644 doc/usage/addrmap.rst create mode 100644 test/cmd/addrmap.c -- 2.7.4
