[PATCH] acpi: Use U-Boot version for OEM_REVISION
by Pali Rohár 06 Oct '21

06 Oct '21

OEM_REVISION is 32-bit unsigned number. It should be increased only when changing software version. Therefore it should not depend on build time. Change calculation to use U-Boot version numbers and set this revision to date number. Prior this change OEM_REVISION was calculated from build date and stored in the same format. After this change macro U_BOOT_BUILD_DATE is not used in other files so remove it from global autogenerated files and also from Makefile.

[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 0/4] crypto: Add new UCLASS_HASH
by Chia-Wei Wang 27 Sep '21

27 Sep '21

This patch series proposes new UCLASS_HASH for hash devices. Thus the hash drivers (SW or HW-accelerated) can be developed in the DM-based fashion. A purely software implemented hash driver is also added under the newly added UCLASS_HASH uclass. In addition, the FIT image hash verification is also updated to leverage the UCLASS_HASH driver if configured. As there is widly spread use of non-DM hash functions (common/hash.c), this patch does not remove them. More patches are needed if UCLASS_HASH is established.

[PATCH] test/py: tpm2: Skip tpm pytest based on env variable

From: T Karthik Reddy <t.karthik.reddy(a)xilinx.com> Tpm test cases relies on tpm device setup. Provide an environment variable "env__tpm_device_test_skip = True" to skip the test case if tpm device is not present. Only needed will have to add variable to the py-test framework.

[PATCH 0/2] Minor misc. cleanups for TI K3 SoCs
by Suman Anna 18 Sep '21

18 Sep '21

Hi Lokesh, The following are two minor cleanups/fixes that I ran into while doing some development work on a newer SoC due to different Kconfig symbols. Following is the patch summary: - Patch #1 makes the ti_sci_protocol.h self-contained when CONFIG_TI_SCI_PROTOCOL is not defined. - Patch #2 defines a release_resources_for_core_shutdown() stub. This function is used in the common code, but yet is expected to be implemented in a SoC-specific source file. regards Suman Suman Anna (2): firmware: ti_sci: Include linux/err.h in ti_sci_protocol.h arm: mach-k3: common: Add a release_resources_for_core_shutdown() stub arch/arm/mach-k3/common.c | 5 +++++ include/linux/soc/ti/ti_sci_protocol.h | 4 +++- 2 files changed, 8 insertions(+), 1 deletion(-) -- 2.32.0
