[PATCH] phy: rockchip: inno-usb2: fix hang when multiple controllers exit
by Icenowy Zheng 12 Nov '21

12 Nov '21

The OHCI and EHCI controllers are both bound to the same PHY. They will both do init and power_on operations when the controller is brought up and both do power_off and exit when the controller is stopped. However, the PHY uclass of U-Boot is not as sane as we thought -- they won't maintain a status mark for PHYs, and thus the functions of the PHYs could be called for multiple times. Calling init/power_on for multiple times have no severe problems, however calling power_off/exit for multiple times have a problem -- the first exit call will stop the PHY clock, and power_off/exit calls after it still trying to write to PHY registers. The write operation to PHY registers will fail because clock is already stopped. Adapt the count mechanism from phy-sun4i-usb to both init/exit and power_on/power_off functions to phy-rockchip-inno-usb2 to fix this problem. With this stopping USB controllers (manually or before booting a kernel) will work.

[PATCH 1/1] video: fix positioning in TrueType console
by Heinrich Schuchardt 28 Oct '21

28 Oct '21

With the patch accurate positioning is possible for mono-typed fonts: Fix the return value of console_truetype_putc_xy(). The current position is passed as parameter x. Some part of x represents a fractional pixel. The return value represents how much the character position must be advanced. This should only comprise the width of the current character and not the preexisting fractional pixel position. Characters are not square. As all characters of a mono-type font we can take the width of any character. 'W' as one of the widest ANSI characters provides also a good value for variable width fonts. The character width must be a float.

From: Matthias Brugger <mbrugger(a)suse.com> For now bootp and uuid code use a weak seed for generating random data. U-Boot as support for RNG devices now, so we should change to code to use them if they are present. This will help mitigate issues like seen in CVE-2019-11690.

[PATCH v2 0/6] dwc3-generic: Add Layerscape support
by Ran Wang 03 Oct '21

03 Oct '21

Hello, The purpose of this patch set is to switch from driver xhci-fsl to dwc3-generic for DWC3 IP on Layerscape platforms. Whith this change, now user can enable USB device mode by merely updating property 'dr_mode' accordingly. I also port some DWC3's errata workaorunds from driver xhci-fsl (by referring to Linux kernel mainline version implemenattion). Besides that, I fixed a PHY init problem which observed on Lyerscape platforms (such as LS1088ardb). Regards, Ran Change in v2: - Remove [2/7] usb: dwc3: add disable receiver detection in P3 quirk, because I found it causes Linux kenrel fail to detect USB device, need further check.

[PATCH] rpi: always set fdt_addr with firmware-provided FDT address
by Mauro Salvini 30 Sep '21

30 Sep '21

Raspberry firmware prepares the FDT blob in memory at an address that depends on both the memory size and the blob size [1]. After commit ade243a211d6 ("rpi: passthrough of the firmware provided FDT blob") this FDT is passed to kernel through fdt_addr environment variable, handled in set_fdt_addr() function in board file. When u-boot environment is persistently saved, if a change happens in loaded FDT (e.g. for a new overlay applied), firmware produces a FDT address different from the saved one, but u-boot still use the saved one because set_fdt_addr() function does not overwrite the fdt_addr variable. So, for example, if there is a script that uses fdt commands for e.g. manipulate the bootargs, boot hangs with error libfdt fdt_check_header(): FDT_ERR_BADMAGIC Removing the fdt_addr variable in saved environment allows to boot. With this patch set_fdt_addr() function always overwrite fdt_addr value.

[PATCH v2 1/2] arm: dts: bcm283x: Add minimal smbios information
by matthias.bgg＠kernel.org 15 Sep '21

15 Sep '21

From: Matthias Brugger <mbrugger(a)suse.com> At present SMBIOS tables are empty, which breaks some use-cases that rely on that. Add some minimal information to fulfill this.
