[U-Boot] Disable phy in application init
by Zvi Vered 27 Nov '18

27 Nov '18

Hello, Upon 'ping', u-boot is trying to initialize PHY. In my case, the PHY is initialized by external hardware, not by MDC\MDIO. In menuconfig, there is no option to exclude CONFIG_PHYLIB -*- Ethernet PHY How should I modify u-boot so that the CPU will not try to initialize PHY ? Thank you, Zvika

[U-Boot] [PATCH v4 0/4] Add Hardware Spinlock class
by Benjamin Gaignard 27 Nov '18

27 Nov '18

version 4: - make timeout loop more robust version 3: - use dev_get_parent - add Review-by version 2: - use -ETIMEDOUT and -ENOSYS for errors cases - do not test if ops is valid - remove useless include - add a private structure to store base address - be more verbose in configuration flag description and commit message - log the error after hwspinlock_get_by_index() This series add a news class to support hardware spinlock. Hardware spinlock could be used to protect critical sections of code between multi-processors. The proposed API remain simple with only 3 functions to be called client: - hwspinlock_get_by_index: get a hardware spinlock by integer index from device-tree node - hwspinlock_lock_timeout: lock the hardware spinlock - hwspinlock_unlock: unlock the hardware spinlock Driver API offert 4 operations: - of_xlate: translate a client's device-tree (OF) hardware specifier - lock: lock the hardware spinlock - unlock: unlock the hardware spinlock - relax: wait time between two calls to lock operations Benjamin Gaignard (4): dm: Add Hardware Spinlock class clk: stm32: add hardware spinlock clock hwspinlock: add stm32 hardware spinlock support pinctrl: stm32: make pinctrl use hwspinlock arch/arm/dts/stm32mp157c-ed1.dts | 8 ++ arch/arm/dts/stm32mp157c.dtsi | 9 ++ arch/sandbox/dts/test.dts | 4 + arch/sandbox/include/asm/state.h | 1 + configs/sandbox_defconfig | 2 + configs/stm32mp15_basic_defconfig | 2 + drivers/Kconfig | 2 + drivers/Makefile | 1 + drivers/clk/clk_stm32mp1.c | 3 + drivers/hwspinlock/Kconfig | 24 ++++++ drivers/hwspinlock/Makefile | 7 ++ drivers/hwspinlock/hwspinlock-uclass.c | 144 ++++++++++++++++++++++++++++++++ drivers/hwspinlock/sandbox_hwspinlock.c | 56 +++++++++++++ drivers/hwspinlock/stm32_hwspinlock.c | 92 ++++++++++++++++++++ drivers/pinctrl/pinctrl_stm32.c | 27 ++++++ include/dm/uclass-id.h | 1 + include/hwspinlock.h | 140 +++++++++++++++++++++++++++++++ test/dm/Makefile | 1 + test/dm/hwspinlock.c | 40 +++++++++ 19 files changed, 564 insertions(+) create mode 100644 drivers/hwspinlock/Kconfig create mode 100644 drivers/hwspinlock/Makefile create mode 100644 drivers/hwspinlock/hwspinlock-uclass.c create mode 100644 drivers/hwspinlock/sandbox_hwspinlock.c create mode 100644 drivers/hwspinlock/stm32_hwspinlock.c create mode 100644 include/hwspinlock.h create mode 100644 test/dm/hwspinlock.c -- 2.15.0

[U-Boot] [PATCH] efi_loader: bootmgr: support BootNext and BootCurrent variable behavior
by AKASHI Takahiro 27 Nov '18

27 Nov '18

See UEFI v2.7, section 3.1.2 for details of the specification. With my efishell command[1], you can try as the following: => efi boot add 1 SHELL ... => efi boot add 2 HELLO ... => efi boot order 1 2 => efi bootmgr (starting SHELL ...) => efi setvar BootNext =H0200 => efi bootmgr (starting HELLO ...) => efi dumpvar <snip ...> BootCurrent: {boot,run}(blob) 00000000: 02 00 .. BootOrder: {boot,run}(blob) 00000000: 01 00 02 00 .... Using "run -e" would be more human-friendly, though.

[U-Boot] [PATCH v1 00/16] Add support for DM_USB and DM_USB_DEV to TI's am335x and am43xx_evm platforms
by Jean-Jacques Hiblot 27 Nov '18

27 Nov '18

This series applies on top of the series "Add support for DM_USB and DM_USB_DEV to TI's K2G platforms" and "Add support for DM_USB and DM_USB_DEV for TI's DRA7 EVMs and AM57 EVMs platforms." The am433x platforms can use the generic DWC3 driver instead of relying on the dwc3-xhci driver. The am335x platforms use the musb controller. With a bit of work it can be made to support DM as well. This series only enables DM_USB and DM_USB_GADGET on am335x_boneblack_vboot. The changes for the other am335x based platforms will come in a subsequent series that reworks the configs of several TI boards. This is part of a work to move all TI's platforms to support DM_USB and DM_USB_DEV. As a side effect it makes it easy to support the full USB RDNIS bootflow (bootrom loads SPL over RNDIS, SPL loads u-boot over RNDIS, u-boot loads the images over RNDIS) This series is made of 3 parts: - some generic changes: rename DM_USB_DEV in DM_USB_GADGET and create UCLASS_USB_GADGET for the USB peripheral drivers. - am437x support for DM_USB and DM_USB_GADGET - am335x support for DM_USB and DM_USB_GADGET Tested on: - am4372 evm - beaglebone black - am335x evm (to verify that it doesn't break anything) Jean-Jacques Hiblot (16): usb: rename CONFIG_DM_USB_DEV as CONFIG_DM_USB_GADGET dm: usb: create a new UCLASS ID for USB gadget devices spl: drivers: Link usb common library to SPL if USB gadget is enabled spl: net: dm: usb: bind the gadget before attempting to load the image phy: omap_usb2: Add support for am437x dwc3-generic: Add support for the am437x board: ti: am43xx: turn on USB clocks dts: Add a u-boot specific dtsi file for the am4372 dts: am4372: Enable USB1 in SPL configs: am43xx_evm: Enable DM_USB and DM_USB_GADGET configs: am43xx: Enable RNDIS support in SPL usb: musb-new: Allow the diver not to use the set_phy_power() callback usb: musb-new: Add support for DM_USB_GADGET arm: am33xx: Register USB controllers if DM_USB is used but not OF_CONTROL configs: am335x_evm: Do not disable DM_USB in SPL configs: am335x_boneblack_vboot: enable DM_USB and RNDIS boot in SPl arch/arm/Kconfig | 4 +- arch/arm/dts/am4372-generic-u-boot.dtsi | 2 + arch/arm/dts/am4372-u-boot.dtsi | 40 +++++++ arch/arm/dts/am437x-gp-evm-u-boot.dtsi | 2 + arch/arm/dts/am437x-idk-evm-u-boot.dtsi | 2 + arch/arm/dts/am437x-sk-evm-u-boot.dtsi | 2 + arch/arm/include/asm/omap_musb.h | 8 ++ arch/arm/mach-omap2/am33xx/board.c | 58 ++++++++-- board/sunxi/board.c | 2 +- board/ti/am43xx/board.c | 22 ++++ common/Makefile | 3 + common/spl/spl_net.c | 4 +- configs/am335x_boneblack_vboot_defconfig | 8 ++ configs/am43xx_evm_defconfig | 17 +++ configs/am57xx_evm_defconfig | 2 +- configs/am57xx_hs_evm_defconfig | 2 +- configs/dra7xx_evm_defconfig | 2 +- configs/dra7xx_hs_evm_defconfig | 2 +- configs/k2g_evm_defconfig | 2 +- configs/k2g_hs_evm_defconfig | 2 +- drivers/Makefile | 1 + drivers/phy/omap-usb2-phy.c | 45 ++++++-- drivers/usb/Kconfig | 2 +- drivers/usb/dwc3/core.c | 2 +- drivers/usb/dwc3/dwc3-generic.c | 7 +- drivers/usb/gadget/ether.c | 2 +- drivers/usb/gadget/udc/Makefile | 4 + drivers/usb/gadget/udc/udc-core.c | 41 ------- drivers/usb/musb-new/am35x.c | 8 +- drivers/usb/musb-new/musb_dsps.c | 8 +- drivers/usb/musb-new/musb_gadget.c | 11 ++ drivers/usb/musb-new/musb_uboot.c | 4 +- drivers/usb/musb-new/omap2430.c | 2 +- drivers/usb/musb-new/sunxi.c | 2 +- drivers/usb/musb-new/ti-musb.c | 179 +++++++++++++++++++++++-------- include/configs/am335x_evm.h | 1 - include/dm/uclass-id.h | 1 + include/linux/usb/gadget.h | 2 +- 38 files changed, 375 insertions(+), 133 deletions(-) create mode 100644 arch/arm/dts/am4372-u-boot.dtsi -- 2.7.4

[U-Boot] [PATCH v3 0/9] efi_loader: fix memory handling
by Heinrich Schuchardt 27 Nov '18

27 Nov '18

The Sandbox uses an address space that is neither the physical nor the virtual address space of the operating system. In the EFI subsystem we should only use addresses that can be used by an EFI application. With the patch series we eliminate the Sandbox addresses from the EFI memory map. In the flattened device tree the Sandbox needs its own address space. So make sure that this is always used here. v3: merge two preexisting patch series resequence the patches to avoid changes to be undone later fix the value of fdtcontroladdr on the sandbox rebase patches Heinrich Schuchardt (9): efi_loader: eliminate sandbox addresses efi_selftest: add test for memory allocation efi_selftest: building sandbox with EFI_SELFTEST efi_loader: macro efi_size_in_pages() fdt: sandbox: correct use of ${fdtcontroladdr} fdt_support: fdt reservations on the sandbox efi_loader: fix memory mapping for sandbox efi_loader: create fdt reservation before copy efi_selftest: check fdt is marked as runtime data cmd/bootefi.c | 56 ++++---- common/board_r.c | 3 +- common/fdt_support.c | 3 +- include/efi_loader.h | 11 +- lib/efi_loader/efi_memory.c | 15 +- lib/efi_selftest/Kconfig | 2 +- lib/efi_selftest/Makefile | 1 + lib/efi_selftest/efi_selftest_memory.c | 187 +++++++++++++++++++++++++ lib/fdtdec.c | 6 +- test/py/tests/test_efi_selftest.py | 10 +- 10 files changed, 246 insertions(+), 48 deletions(-) create mode 100644 lib/efi_selftest/efi_selftest_memory.c -- 2.19.1
