[U-Boot] [RESEND] [PATCH v3 0/8] Convert i.MX7 WaRP7 ports to DM
by Bryan O'Donoghue 30 Jan '19

30 Jan '19

V3-Resend: - Looks like this set got lost in the ether, resending. V3: - Fix Lucas' mail address "Auer, Lucas" makes git send-mail choke V2: - Add review-by as indicated - Peng Fan - Squash commit 4 and 5 from v1 - Peng Fan - Leave usdhc1 intact because of alias of mmc0 to usdhc3 - Bryan - Add correction for spelling mistake in imx7d-pinfunc.h - Lukas Auer - Imports imx7s-warp7.dts from kernel unmodified as a result of #1 - Bryan V1: This series does a minimal conversion of WaRP7 and the BL33 version of WaRP7 to the DM. Pinctrl, GPIO, I2C, Regulators, PMIC and MMC are converted. Later patches will convert USB and UART. Bryan O'Donoghue (8): arm: dts: imx7: Correct spelling mistake in GPIO name arm: dts: imx7s-warp: Import Linux warp7 dts arm: imx7s-warp: Add DT file hooks arm: imx7s-warp: Convert to DM MMC initialization arm: dts: imx7s-warp: Create alias for mmc0 to &usdhc3 warp7: defconfig: Switch on IMX7 GPIO/pinctrl for both ports warp7: defconfig: Switch to DM for I2C arm: imx7s-warp: Convert to DM PMIC arch/arm/dts/Makefile | 3 +- arch/arm/dts/imx7d-pinfunc.h | 6 +- arch/arm/dts/imx7s-warp.dts | 442 +++++++++++++++++++++++++++++++++++ board/warp7/warp7.c | 85 +------ configs/warp7_bl33_defconfig | 14 +- configs/warp7_defconfig | 14 +- include/configs/warp7.h | 8 - 7 files changed, 484 insertions(+), 88 deletions(-) create mode 100644 arch/arm/dts/imx7s-warp.dts -- 2.20.0

[U-Boot] [PATCH 2/2] ARM: DTS: imx6q-logicpd: Update DTS/DTSI files
by Adam Ford 30 Jan '19

30 Jan '19

The i.MX6 SOM and development kits have undergone significant updates and changes over the past few months. This re-sync's the U-Boot with Logic PD's BSP.

[U-Boot] [PATCH] imx: hab: Convert non-NULL IVT DCD pointer warning to an error
by Breno Matheus Lima 30 Jan '19

30 Jan '19

The following NXP application notes and manual recommend to ensure the IVT DCD pointer is Null prior to calling HAB API authenticate_image() function: - AN12263: HABv4 RVT Guidelines and Recommendations - AN4581: Secure Boot on i.MX50, i.MX53, i.MX 6 and i.MX7 Series using HABv4 - CST docs: High Assurance Boot Version 4 Application Programming Interface Reference Manual Commit ca89df7dd46f ("imx: hab: Convert DCD non-NULL error to warning") converted DCD non-NULL error to warning due to the lack of documentation at the time of first patch submission. We have warned U-Boot users since v2018.03, and it makes sense now to follow the NXP recommendation to ensure the IVT DCD pointer is Null. DCD commands should only be present in the initial boot image loaded by the SoC ROM. Starting in HAB v4.3.7 the HAB code will generate an error if a DCD pointer is present in an image being authenticated by calling the HAB RVT API. Older versions of HAB will process and run DCD if it is present, and this could lead to an incorrect authentication boot flow.

[U-Boot] [PATCH v2 00/11] arm: Colibri iMX7 fixes and DM_MMC conversion
by Stefan Agner 30 Jan '19

30 Jan '19

From: Stefan Agner <stefan.agner(a)toradex.com> This patchset fixes some small issues with Colibri iMX7 and converts the board to use DM_MMC. It also adds the so far missing configuration for the eMMC variant. This patchset gets rid of all but one deprecation warning. The remaining warning is due to CONFIG_USB still being used. Fixing this is not entirly trivial due to missing GPIO host/ peripheral switch capabilities and will be tackled later. -- Stefan Changes in v2: - Remove imx7-colibri.dtb from Makefile - Remove unnecessary properties - New patch - New patch - Add CONFIG_FIT/DFU/CRC32_VERIFY/CMD_GPT/DFU_MMC and FAT_WRITE Stefan Agner (11): colibri_imx7: fix boot commands arm: dts: imx7: colibri: split dt for raw NAND and eMMC devices configs: colibri_imx7: enable DM for raw NAND devices configs: colibri_imx7: use separate device tree arm: dts: imx7: colibri: add usdhci peripherals to device tree configs: colibri_imx7: use DM_MMC colibri_imx7: drop legacy usdhc support configs: colibri_imx7: enable CAAM driver configs: colibri_imx7: use DFU for NAND instead of MMC configs: colibri_imx7: use distro defaults configs: add default configuraiton for Colibri iMX7 with eMMC arch/arm/dts/Makefile | 3 +- arch/arm/dts/imx7-colibri-emmc.dts | 47 +++++++++ arch/arm/dts/imx7-colibri-rawnand.dts | 46 +++++++++ .../{imx7-colibri.dts => imx7-colibri.dtsi} | 65 ++++++------- board/toradex/colibri_imx7/MAINTAINERS | 3 + board/toradex/colibri_imx7/colibri_imx7.c | 97 ------------------- configs/colibri_imx7_defconfig | 27 +++--- configs/colibri_imx7_emmc_defconfig | 66 +++++++++++++ include/configs/colibri_imx7.h | 5 +- 9 files changed, 207 insertions(+), 152 deletions(-) create mode 100644 arch/arm/dts/imx7-colibri-emmc.dts create mode 100644 arch/arm/dts/imx7-colibri-rawnand.dts rename arch/arm/dts/{imx7-colibri.dts => imx7-colibri.dtsi} (68%) create mode 100644 configs/colibri_imx7_emmc_defconfig -- 2.20.1

[U-Boot] [PATCH] pinctrl: imx: Fix select input issue
by Ye Li 30 Jan '19

30 Jan '19

The pinctrl supports to set any bit in input register on iMX6 if the MSB of input value is 0xff. But the driver uses signed int for input value, so when executing the codes below, it won't meet. Because this is arithmetic right shift. if (input_val >> 24 == 0xff) Fix the issue by changing the input_val, config_val and mux_mode to u32.

[U-Boot] [PATCH] imx: Fix potential lmb memory overwritten by stack
by Ye Li 30 Jan '19

30 Jan '19

At default, u-boot reserves the memory from SP - 4KB to DRAM end for lmb in arch_lmb_reserve. So lmb won't allocate any memory from it. But we found the 4K gap for SP is not enough now, because some FDT updating operations are added in our u-boot before jumping to kernel, which needs larger stack. This causes the lmb allocated memory is overwritten by stack. Fix the issue by implementing the board_lmb_reserve to reserve from SP - 16KB to memory end for lmb.
