ARM: mvebu: enable SPI for helios4 and sata and uart images for clearfog
by dgilmore＠redhat.com 11 Feb '21

11 Feb '21

In an effort to build SPI images for clearfog and helios4 I needed to make some minor changes to the dts and Kconfig for the helios4 and set some variables for UART and SATA images for ClearFog. Version 2 dropped changes for db-mv784mp-gp as the board turns out to be currently broken, the serial port is not available and the system bails after loading the SPL the dts changes for the helios4 have been shrunk back to remove everything not needed or valid Dennis

[PATCH v2 1/2] imx8mp: configs: add support for distro boot commands
by Alice Guo (OSS) 10 Feb '21

10 Feb '21

From: Alice Guo <alice.guo(a)nxp.com> Supported boot device types in iMX8MP: MMC. CONFIG_CMD_PART is added for command part and CONFIG_CMD_FS_GENERIC is for command fstype. scriptaddr is the location in RAM where boot.scr.uimg/boot.scr will be loaded to prior to execution. kernel_addr_r is the location in RAM where the kernel will be loaded to. Delete unnecessary environment variables because "run distro_bootcmd" is set to be the default boot mode. On the iMX8MP platform I used, "mmc1" represents SD card and "mmc2" represents eMMC.

[PATCH 0/3] arm: mvebu: Espressobin: Set default env values at runtime
by Pali Rohár 08 Feb '21

08 Feb '21

This patch series set default env values of $fdtfile and $ethNaddr for Espressobin board at runtime. It fixes two main issues on Espressobin board that 'env default -a' completely erases permanent board MAC addresses and also erase $fdtfile variable which is needed for booting Linux kernel via distro boot. Lot of people were complaining about erasing permanent MAC addresses by U-boot on this board and due to this issue some linux distributions started using static hardcoded MAC addresses for all Espressobin boards to workaround this issue. Apparently erase of MAC addresses or usage of static hardcoded value caused more issues on network (e.g. inability to connect two of these boards to the same network).

[PATCH 00/13] Nokia RX-51: Fix USB TTY console and enable it
by Pali Rohár 01 Feb '21

01 Feb '21

This patch series fix usbtty code (serial console via USB peripheral mode), fix underlying musb peripheral code, fix compilation of CONFIG_USB_DEVICE (used by usbtty), remove unused Nokia RX-51 code to decrease size of U-Boot binary and finally enable usbtty serial console for Nokia RX-51. With this patch series debugging of Nokia RX-51 can be done also via USB serial console. On computer this serial console is accessible via /dev/ttyACM0 device. With current implementation there is an issue in musb driver that it loose receiving bytes from USB bus when too many a characters are send over USB tty from computer. Typing on keyboard to kermit terminal connected to /dev/ttyACM0 is working fine. But pasting more more bytes to terminal cause data lost on receiving side. I do not know where is the issue or how to fix it (it looks like that data are lost at low level when reading them from msub FIFO hardware) but typing on keyboard is working fine. This is rather issue for sending files via x/y/z-modem or kermit protocol. Currently U-Boot is not able to receive any file via usbtty with musb driver due to this issue.

[PATCH 00/11] dm: Simplify livetree handling
by Simon Glass 01 Feb '21

01 Feb '21

At present there are separate code paths for livetree and flattree in places where they can be made common. Also there are a few functions that support flattree but can be moved over to use the livetree API (i.e. ofnode instead of a DT offset). This series tidies up these areas. Simon Glass (11): dm: core: Rename device_bind() to device_bind_offset() dm: core: Rename device_bind_ofnode() to device_bind() dm: core: Add a livetree function to check node status dm: Remove uses of device_bind_offset() dm: Drop uses of dev_set_of_offset() dm: core: Drop dev_set_of_offset() dm: core: Drop device_bind_offset() dm: core: Add an ofnode function to get the devicetree root dm: core: Combine the flattree and livetree binding code dm: core: Drop unused parameter from dm_scan_fdt() dm: core: Drop unused parameter from dm_extended_scan_fdt() drivers/clk/at91/compat.c | 20 ++--- drivers/clk/clk.c | 2 +- drivers/core/device.c | 10 +-- drivers/core/ofnode.c | 10 +++ drivers/core/root.c | 97 ++++++--------------- drivers/firmware/scmi/scmi_agent-uclass.c | 4 +- drivers/gpio/dwapb_gpio.c | 4 +- drivers/gpio/mt7621_gpio.c | 5 +- drivers/gpio/s5p_gpio.c | 6 +- drivers/gpio/sunxi_gpio.c | 5 +- drivers/gpio/tegra186_gpio.c | 3 +- drivers/gpio/tegra_gpio.c | 4 +- drivers/misc/i2c_eeprom.c | 4 +- drivers/mtd/spi/sandbox.c | 2 +- drivers/net/mvpp2.c | 4 +- drivers/pci/pci-uclass.c | 4 +- drivers/pci/pci_mvebu.c | 4 +- drivers/pinctrl/broadcom/pinctrl-bcm283x.c | 2 +- drivers/pinctrl/meson/pinctrl-meson.c | 5 +- drivers/pinctrl/mscc/pinctrl-jr2.c | 2 +- drivers/pinctrl/mscc/pinctrl-luton.c | 2 +- drivers/pinctrl/mscc/pinctrl-ocelot.c | 2 +- drivers/pinctrl/mscc/pinctrl-serval.c | 2 +- drivers/pinctrl/mscc/pinctrl-servalt.c | 2 +- drivers/pinctrl/mvebu/pinctrl-armada-37xx.c | 8 +- drivers/usb/host/usb-uclass.c | 4 +- include/dm/device-internal.h | 10 +-- include/dm/device.h | 5 -- include/dm/ofnode.h | 23 +++++ include/dm/root.h | 8 +- test/dm/core.c | 6 +- test/dm/ofnode.c | 12 +++ test/dm/test-fdt.c | 4 +- test/dm/test-main.c | 4 +- 34 files changed, 130 insertions(+), 159 deletions(-) -- 2.29.2.454.gaff20da3a2-goog

[PATCH 0/8] spl: fit: Play nicely with OP-TEE and Linux
by Alexandru Gagniuc 31 Jan '21

31 Jan '21

This patch series is part of a larger effort to get linux to boot really fast alongside a secure OS. One piece of the puzzle is getting Linux and OP-TEE to boot straight from SPL. This is where the FIT image comes in. The "simple" fit code was mostly ready for this, although it was quite difficult to navigate. As I was figuring out the required changes, I realized I had also managed to do some major refactoring. In fact, of the eight changes, (6) are refactoring patches, and (2) are functional changes. I wish I could have written this with a negative line count. I have unfortunately failed at that, and this series will be adding 12 lines to u-boot. The takeaway is that the following type FIT can be loaded from SPL directly: images { optee@1 { type = "tee"; os = "tee"; ... }; kernel@1 { type = "kernel"; os = "linux"; ... }; fdt(a)devicetree.dtb { ... } fdt@bootargs { ... }; }; configurations { conf@quickboot { kernel = "optee@1"; fdt = "fdt(a)stm32mp157c-ev1.dtb", "fdt@bootargs"; loadables = "kernel@1"; }; }; This series is designed to apply to u-boot/next: * 8351a29d2d Merge tag 'dm-pull-14dec20' of git://git.denx.de/u-boot-dm into next Alexandru Gagniuc (8): spl: fit: Drop 'length' argument to board_spl_fit_post_load() spl: fit: Factor out FIT parsing and use a context struct spl: fit: Pass FIT context via a structure pointer spl: fit: Remove useless loop in spl_fit_get_image_name() spl: fit: Only look up FIT configuration node once image: Do not #if guard board_fit_config_name_match() prototype spl: fit: Replace #ifdef blocks with more readable constructs spl: fit: Load devicetree when a Linux payload is found arch/arm/mach-imx/spl.c | 5 +- common/spl/spl_fit.c | 260 +++++++++++++++++++++------------------- include/image.h | 3 - include/spl.h | 2 +- 4 files changed, 141 insertions(+), 129 deletions(-) -- 2.26.2
