by Simon Glass 15 Aug '22

15 Aug '22

This series contains some minor enhancements for the TPM code to make it work with Chromium OS verified boot. Simon Glass (8): tpm: Export the TPM-version functions tpm: Require a digest source when extending the PCR tpm: Correct the permissions command in TPMv1 tpm: Correct the define-space command in TPMv2 tpm: sandbox: Allow init of TPM in a different phase tpm: Allow reporting the internal state tpm: Implement state command for Cr50 tpm: Allow commiting non-volatile data cmd/tpm-common.c | 20 ++++++ cmd/tpm-user-utils.h | 2 + cmd/tpm-v1.c | 3 +- cmd/tpm-v2.c | 3 + cmd/tpm_test.c | 5 +- drivers/tpm/cr50_i2c.c | 117 +++++++++++++++++++++++++++++++++ drivers/tpm/tpm-uclass.c | 10 +++ drivers/tpm/tpm2_tis_sandbox.c | 17 ++++- include/tpm-common.h | 20 ++++++ include/tpm-v2.h | 68 +++++++++++++++++++ include/tpm_api.h | 18 ++++- lib/tpm-v1.c | 5 +- lib/tpm-v2.c | 64 ++++++++++++++++-- lib/tpm_api.c | 102 ++++++++++++++-------------- test/dm/Makefile | 1 + test/dm/tpm.c | 34 ++++++++++ 16 files changed, 419 insertions(+), 70 deletions(-) create mode 100644 test/dm/tpm.c -- 2.35.1.574.g5d30c73bfb-goog

[PATCH v3] pinctrl: nuvoton: Add NPCM8xx pinctrl driver
by Stanley Chu 13 Aug '22

13 Aug '22

Add Nuvoton BMC NPCM845 Pinmux and Pinconf support. Signed-off-by: Stanley Chu <yschu(a)nuvoton.com> --- v3: - separate group names and function names in different tables to allow for adding additional functions v2: - drop the WDnRCRB/CORSTCB register

[PATCH v2 0/3] arm: layerscape: Add sfp driver
by Sean Anderson 13 Aug '22

13 Aug '22

This adds a driver for the Security Fuse Processor (SFP). It only supports Trust Architecture (TA) 2.1 SFPs, but it should be fairly trivial to add support for TA 3.1 SFPs. See [1] for Linux bindings/driver support. [1] https://lore.kernel.org/linux-arm-kernel/20220422145147.2210587-1-sean.ande… Changes in v2: - Use the sfp clock directly, instead of assuming we get the platform clock. This corresponds better to what other drivers on these devices do. - Rename clock to "sfp" to be more descriptive. - update the clockgen node for ls1021a Sean Anderson (3): arm: layerscape: Add sfp driver ARM: dts: ls1021a: update the clockgen node arch: layerscape: Add SFP binding MAINTAINERS | 5 + arch/arm/dts/fsl-ls1012a.dtsi | 7 + arch/arm/dts/fsl-ls1043a.dtsi | 7 + arch/arm/dts/fsl-ls1046a.dtsi | 7 + arch/arm/dts/ls1021a.dtsi | 87 ++++----- drivers/misc/Kconfig | 14 ++ drivers/misc/Makefile | 1 + drivers/misc/ls2_sfp.c | 350 ++++++++++++++++++++++++++++++++++ 8 files changed, 426 insertions(+), 52 deletions(-) create mode 100644 drivers/misc/ls2_sfp.c -- 2.35.1.1320.gc452695387.dirty

[PATCH v2 0/5] DFU: Update dfu_alt_info parser etc.
by Masami Hiramatsu 10 Aug '22

10 Aug '22

Hi, Here is the 2nd version of improving DFU subsystem series. This improves dfu_alt_info parser and fixing documents etc. In this version I fixed a build error of cmd/dfu.c so that it can be build without DFU_OVER_USB and DFU_OVER_TFTP (in this case, the platform will use the DFU only for EFI capsule update.) When I was debuging my patch for updating dfu_alt_info on the DeveloperBox platform, I found that dfu_alt_info parser didn't accept redundant spaces and tabs. Also the dfu.rst description seems wrong. Moreover, there is no way to check whether the parser parses the dfu_alt_info correctly. These patches fixes such issues. [1/5] is just for avoiding buffer overrun, [2/5] and [3/5] improves dfu_alt_info parser to accept redundant spaces and tabs, and check the number of arguments strictly so that the parser (and user) can notice any unexpected parameters. [4/5] fixes the documents (there seems some wrong description maybe coming from copy&paste). [5/5] allows user to run 'dfu list' even if the platform doesn't support DFU_OVER_USB nor DFU_OVER_TFTP. Thank you, --- Masami Hiramatsu (5): DFU: Do not copy the entity name over the buffer size DFU: Accept redundant spaces and tabs in dfu_alt_info DFU: Check the number of arguments and argument string strictly doc: usage: DFU: Fix dfu_alt_info document cmd/dfu: Enable 'dfu list' command without DFU_OVER_USB cmd/dfu.c | 8 +++---- doc/usage/dfu.rst | 57 ++++++++++++++++++++++++++++++++++-------------- drivers/dfu/dfu.c | 37 ++++++++++++++++++++++++------- drivers/dfu/dfu_mmc.c | 55 +++++++++++++++++++++++++++------------------- drivers/dfu/dfu_mtd.c | 34 +++++++++++++++++++---------- drivers/dfu/dfu_nand.c | 34 ++++++++++++++++++----------- drivers/dfu/dfu_ram.c | 24 ++++++++++---------- drivers/dfu/dfu_sf.c | 34 ++++++++++++++++++----------- drivers/dfu/dfu_virt.c | 5 +++- include/dfu.h | 33 ++++++++++++++++++---------- 10 files changed, 205 insertions(+), 116 deletions(-) -- Masami Hiramatsu <masami.hiramatsu(a)linaro.org>

[PATCH] net: dm9000: Correctly handle empty FIFO
by Marek Vasut 08 Aug '22

08 Aug '22

Assign packet pointer only in case the MAC reports anything in the FIFO. In case the MAC indicates empty FIFO, return 0 to pass that information to the network stack.

[PATCH v2 1/2] net: phy: marvell: Support reg config via "marvell, reg-init" DT property
by Stefan Roese 08 Aug '22

08 Aug '22

This patch adds support for the "marvell,reg-init" DT property, which is used to describe board specific Marvell PHY register configurations in the board dts file. This DT property is supported in the Linux Kernel since a longer time. Adding it to U-Boot now, enables the boards which describe the register settings in their DT files here as well. I've included calling this marvell_of_reg_init() to all foo_config() functions in this patch as well. If CONFIG_DM_ETH is not set, there is no ofnode, or no "marvell,reg-init" property, the PHY initialization is unchanged. The function marvell_of_reg_init() is a port of the Linux version. Please note that I explicitly did not add error checking and handling to the U-Boot version, as this is basically not done for phy_read/write in this Marvell PHY code. This will be used by the upcoming ethernet support on the MIPS Octeon EBB 7304 board.

[PATCH u-boot-marvell] arm: mvebu: Do not define or overwrite vectors in SPL build
by Pali Rohár 05 Aug '22

05 Aug '22

U-Boot SPL is executed by the BootROM. And BootROM expects that U-Boot SPL code returns back to the BootROM. Reset vectors during execution of U-Boot SPL should not be changed as BootROM does not expect it and uses its own reset vectors. Add ifdefs which disable overwriting reset vectors for 32-bit mvebu platforms on which U-Boot SPL should returns back to the BootROM.

[PATCH 1/3] mmc: fsl_esdhc_imx: use VENDORSPEC_FRC_SDCLK_ON when necessary
by haibo.chen＠nxp.com 27 Jul '22

27 Jul '22

From: Haibo Chen <haibo.chen(a)nxp.com> After commit f132aab40327 ("Revert "mmc: fsl_esdhc_imx: use VENDORSPEC_FRC_SDCLK_ON to control card clock output""), it involve issue in mmc_switch_voltage(), because of the special design of usdhc. For FSL_USDHC, it do not implement VENDORSPEC_CKEN/PEREN/HCKEN/IPGEN, these are reserved bits(Though RM contain the definition of these bits, but actually internal IC logic do not implement, already confirm with IC team). Instead, use VENDORSPEC_FRC_SDCLK_ON to gate on/off the card clock output. Here is the definition of this bit in RM: [8] FRC_SDCLK_ON Force CLK output active Do not set this bit to 1 unless it is necessary. Also, make sure that this bit is cleared when uSDHC’s clock is about to be changed (frequency change, clock source change, or delay chain tuning). 0b - CLK active or inactive is fully controlled by the hardware. 1b - Force CLK active In default, the FRC_SDCLK_ON is 0. This means, when there is no command or data transfer on bus, hardware will gate off the card clock. But in some case, we need the card clock keep on. Take IO voltage 1.8v switch as example, after IO voltage change to 1.8v, spec require gate off the card clock for 5ms, and gate on the clock back, once detect the card clock on, then the card will draw the dat0 to high immediately. If there is not clock gate off/on behavior, some card will keep the dat0 to low level. This is the reason we fail in mmc_switch_voltage(). To fix this issue, and concern that this is only the fsl usdhc hardware design limitation, set the bit FRC_SDCLK_ON in the beginning of the wait_dat0() and clear it in the end. To make sure the 1.8v IO voltage switch process align with SD specification. For standard tuning process, usdhc specification also require the card clock keep on, so also add these behavior in fsl_esdhc_execute_tuning().
