[PATCH 0/3] Introduce new sign binman's option
by Ivan Mikhaylov 18 Feb '23

18 Feb '23

From: Ivan Mikhaylov <ivan.mikhaylov(a)siemens.com> This patch introduces prototype of new sign binman's option. Enhancing the sign procedure, as example: mkimage -G privateky -r -o sha256,rsa4096 -F fit.fit binman replace -i flash.bin -f fit.fit fit into: binman sign -i flash.bin -k privatekey -a sha256,rsa4096 -f fit.fit fit It works with extracted FIT container and image, which provides key signing and replacing FIT container in directed image. Also, I'll add additional enhancement in future to this procedure with skipping on FIT container and providing extract->sign->replace in whole instead of sign->replace with documentation update and test as well. As example: binman sign -i flash.bin -k privatekey -a sha256,rsa4096 -f fit Ivan Mikhaylov (3): binman: add sign option for binman binman: add documentation for binman sign option binman: add test for sign option tools/binman/binman.rst | 10 +++++ tools/binman/cmdline.py | 13 ++++++ tools/binman/control.py | 26 +++++++++++- tools/binman/ftest.py | 42 +++++++++++++++++++ tools/binman/test/225_fit_sign.dts | 67 ++++++++++++++++++++++++++++++ 5 files changed, 157 insertions(+), 1 deletion(-) create mode 100644 tools/binman/test/225_fit_sign.dts -- 2.35.1

[PATCH 1/2 v3] tpm: add a function that performs selftest + startup
by Ilias Apalodimas 17 Feb '23

17 Feb '23

As described in [0] if a command requires use of an untested algorithm or functional module, the TPM performs the test and then completes the command actions. Since we don't check for TPM_RC_NEEDS_TEST (which is the return code of the TPM in that case) and even if we would, it would complicate our TPM code for no apparent reason, add a wrapper function that performs both the selftest and the startup sequence of the TPM. It's worth noting that this is implemented on TPMv2.0. The code for 1.2 would look similar, but I don't have a device available to test.

[PATCH v2 00/17] Basic StarFive JH7110 RISC-V SoC support
by Yanhong Wang 16 Feb '23

16 Feb '23

This series of patches base on the latest branch/master, and add support for the StarFive JH7110 RISC-V SoC and VisionFive V2 board. In order for this to be achieved, the respective DT nodes have been added, and the required defconfigs have been added to the boards' defconfig. What is more, the basic required DM drivers have been added, such as reset, clock, pinctrl, uart, ram etc. Note that the register base address of reset controller is same with the clock controller. Therefore, there is no device tree node alone for reset driver. It binds device node in the clock driver. The u-boot-spl and u-boot has been tested on the VisionFive V2 boards which equip with JH7110 SoC and works normally. For more information and support, you can visit RVspace wiki[1]. [1] https://wiki.rvspace.org/ Changes in v2: - Renamed file 'jh7110-regs.h' to 'regs.h'. - Reworded the clear L2 LIM memory code in C. - Removed flash init call in 'spl_soc_init' function. - Reworded the clock driver. - Rename the macro 'SET_DIV' to 'ASSIGNED_CLOCK_PARENTS' in 'spl.c'. - Moved the device tree node 'dmc@15700000' from 'jh7110-u-boot.dtsi' to 'starfive_visionfive2-u-boot.dtsi'.

bind/unbind command not working for usb_ether
by Tim Harvey 15 Feb '23

15 Feb '23

Greetings, I'm trying to understand how to use the U-Boot bind command to bind the usb_ether driver to the usb class to register a USB ethernet gadget network device as referenced in: commit 02291d83fdaaf ("doc: add bind/unbind command documentation") commit 49c752c93a78 ("cmd: Add bind/unbind commands to bind a device to a driver from the command line") I have enabled: CONFIG_DM_USB=y CONFIG_USB_GADGET=y CONFIG_USB_ETHER=y However the 'usb_ether' driver is never registered and thus doesn't appear in a 'dm tree' list and can't be bound to the usb controller. With the help of Heiko I've found two ways to get the usb_ether driver to register: dt-way: - add of match in ether.c: diff --git a/drivers/usb/gadget/ether.c b/drivers/usb/gadget/ether.c index 63d552bc8b..8e2a05a5af 100644 --- a/drivers/usb/gadget/ether.c +++ b/drivers/usb/gadget/ether.c @@ -2690,10 +2690,16 @@ int usb_ether_init(void) return 0; } +static const struct udevice_id usb_ether_ids[] = { + { .compatible = "gadget,usb_ether" }, + { } +}; + U_BOOT_DRIVER(eth_usb) = { .name = "usb_ether", .id = UCLASS_ETH, .probe = usb_eth_probe, + .of_match = usb_ether_ids, .ops = &usb_eth_ops, .priv_auto_alloc_size = sizeof(struct ether_priv), .platdata_auto_alloc_size = sizeof(struct eth_pdata), - then add it directly in your board u-boot.dts: +&usbotg1 { + usb_ether0 { + compatible = "gadget,usb_ether"; + status = "okay"; + }; +}; The non-dt way: - bind it manually in board code with: { struct udevice *dev; struct udevice *usb_dev; int ret; ret = uclass_first_device(UCLASS_USB, &usb_dev); if (!usb_dev || ret) printf("%s: No USB device found\n", __func__); ret = device_bind_driver(usb_dev, "usb_ether", "usb_ether", &dev); if (!dev || ret) printf("%s: usb - not able to bind usb_ether device\n", __func__); } - Note that this is the same code from usb_ether_init() but with UCLASS_USB instead of UCLASS_USB_GADGET_GENERIC What is the intended way to bind the usb_ether gadget device at runtime? Additionally Heiko found that once bound and usb_ether is registered as a network device using a network command like ping/tftpboot calls usb_setup_ehci_gadget() which removes the USB driver ... and so also the child usb ethernet gadget device then re-probes only the usb driver and not the gadget thus fails. I compared this to how the 'ums' command works and that also removes the usb driver and child nodes but because ums isn't a gadget driver it doesn't get removed and works. Best Regards, Tim

[PATCH] fs/btrfs: handle data extents, which crosss stripe boundaries, correctly
by Qu Wenruo 13 Feb '23

13 Feb '23

[BUG] Since btrfs supports single device RAID0 at mkfs time after btrfs-progs v5.14, if we create a single device raid0 btrfs, and created a file crossing stripe boundary: # mkfs.btrfs -m dup -d raid0 test.img # mount test.img mnt # xfs_io -f -c "pwrite 0 128K" mnt/file # umount mnt Since btrfs is using 64K as stripe length, above 128K data write is definitely going to cross at least one stripe boundary. Then u-boot would fail to read above 128K file: => host bind 0 /home/adam/test.img => ls host 0 < > 131072 Fri Dec 30 00:18:25 2022 file => load host 0 0 file BTRFS: An error occurred while reading file file Failed to load 'file' [CAUSE] Unlike tree blocks read, data extent reads doesn't consider cases in which one data extent can cross stripe boundary. In read_data_extent(), we just call btrfs_map_block() once and read the first mapped range. And if the first mapped range is smaller than the desired range, it would return error. But since even single device btrfs can utilize RAID0 profiles, the first mapped range can only be at most 64K for RAID0 profiles, and cause false error. [FIX] Just like read_whole_eb(), we should call btrfs_map_block() in a loop until we read all data. Since we're here, also add extra error messages for the following cases: - btrfs_map_block() failure We already have the error message for it. - Missing device This should not happen, as we only support single device for now. - __btrfs_devread() failure With this bug fixed, btrfs driver of u-boot can properly read the above 128K file, and have the correct content: => host bind 0 /home/adam/test.img => ls host 0 < > 131072 Fri Dec 30 00:18:25 2022 file => load host 0 0 file 131072 bytes read in 0 ms => md5sum 0 0x20000 md5 for 00000000 ... 0001ffff ==> d48858312a922db7eb86377f638dbc9f ^^^ Above md5sum also matches.

[PATCH 0/5] vidconsole: refactoring and support for wider fonts
by Dzmitry Sankouski 13 Feb '23

13 Feb '23

Modern mobile phones typically have high pixel density. Bootmenu is hardly readable on those with 8x16 font. This patch series aims to add wider fonts for devices with high ppi. Add 16x32 ter font from linux, and allow font size configuration. Use new font in starqltechn board. Note: Only tested with 32BPP configuration. 8BPP and 16BPP testing may needed. I cannot do it, because I don't have such devices.
