soft_spi does not get probed in DM
by Fabio Estevam 29 Jan '20

29 Jan '20

Hi Jagan, On a mx7dsabresd board I am not being able to probe the soft_spi driver using DM with mainline U-Boot. Device tree used is the same one as used in the kernel (imx7d-sdb.dts). soft_spi driver is used to communicate with a I/O expander (supported via CONFIG_DM_74X164), but it can't get probed: spi 0 [ ] soft_spi |-- spi4 which causes the the I/O expander to not get probed as well. What needs to be done for soft_spi to get probed in DM? The "spi-gpio" compatible is present, CONFIG_SPI_SOFT is enabled. We need to use the I/O expander to reset the Ethernet PHY and bring Ethernet functionality back. Thanks, Fabio Estevam

[U-Boot] [PATCH v2 0/9] miscellaneous ubispl and ubi improvements
by Markus Klotzbuecher 29 Jan '20

29 Jan '20

From: Markus Klotzbuecher <markus.klotzbuecher(a)kistler.com> This series contains a couple of UBI and UBI SPL improvements, notably a ubispl extension to allow loading volumes by name. The motivation is to use the UBI atomic volume rename functionality to allow double copy software updates of U-Boot on UBI. To do that we configured the SPL to always load the same volume name (e.g. "u-boot"), and the software updater always installs into the secondary volume "u-boot_r". After a successful upgrade, these two volume names are switched. This extension is protected by #ifdefs as it will somewhat slow down loading of volumes by id. This is because the code needs to disable the optimization of ignoring all volume ids which are not to-be-loaded, since these can only be resolved after attaching. We have tested both with and without fastmap enabled and both paths seems to work reliably. As per Heikos request, this v2 adds two patches that migrate the omap2plus and at91 CONFIG_ENV_* to defconfigs and likewise for the two boards using ubispl. The first migration was supported by an extension to the moveconfig script (patch 1) to expand simple expressions. Both migrations were tested to be binary equal before and after the change. Changes v2: - Add a patch (1) for moveconfig to expand simple expressions - Add patch (3) to move at91 and omap2plus CONFIG_ENV_ to defconfigs - Add patch (7) to migrate boards using ubispl to KConfig - Add missing commit messages - Indicate version of kernel code which was used in ubispl Hamish Guthrie (2): env: ubi: support configurable VID offset ubispl: add support for loading volumes by name Markus Klotzbuecher (7): moveconfig: expand simple expressions env: ubi: KConfig: add CONFIG_ENV_UBI_VOLUME_REDUND at91, omap2plus: configs: migrate CONFIG_ENV_ to defconfigs ubi: fix UBI_SILENCE_MSG ubispl: migrate configuration to Kconfig configs: migrate ubispl boards to KConfig ubispl: introduce separate CONFIG_UBI_SPL_SILENCE_MSG common/spl/Kconfig | 98 ++++++++ common/spl/spl_ubi.c | 7 + configs/am335x_guardian_defconfig | 2 + configs/am335x_igep003x_defconfig | 16 ++ configs/am335x_pdu001_defconfig | 1 + configs/am335x_shc_defconfig | 2 + configs/am335x_shc_ict_defconfig | 2 + configs/am335x_shc_netboot_defconfig | 2 + configs/am335x_shc_sdboot_defconfig | 2 + configs/am335x_sl50_defconfig | 1 + configs/am43xx_evm_defconfig | 1 + configs/am43xx_evm_qspiboot_defconfig | 3 + configs/am43xx_evm_rtconly_defconfig | 1 + configs/am43xx_evm_usbhost_boot_defconfig | 1 + configs/am43xx_hs_evm_defconfig | 1 + configs/at91rm9200ek_defconfig | 3 + configs/at91rm9200ek_ram_defconfig | 3 + configs/at91sam9260ek_dataflash_cs0_defconfig | 3 + configs/at91sam9260ek_dataflash_cs1_defconfig | 3 + configs/at91sam9261ek_dataflash_cs0_defconfig | 3 + configs/at91sam9261ek_dataflash_cs3_defconfig | 3 + configs/at91sam9263ek_dataflash_cs0_defconfig | 3 + configs/at91sam9263ek_dataflash_defconfig | 3 + configs/at91sam9263ek_norflash_boot_defconfig | 3 + configs/at91sam9263ek_norflash_defconfig | 3 + configs/at91sam9g10ek_dataflash_cs0_defconfig | 3 + configs/at91sam9g10ek_dataflash_cs3_defconfig | 3 + configs/at91sam9g20ek_2mmc_defconfig | 2 + configs/at91sam9g20ek_dataflash_cs0_defconfig | 3 + configs/at91sam9g20ek_dataflash_cs1_defconfig | 3 + configs/at91sam9m10g45ek_mmc_defconfig | 1 + configs/at91sam9n12ek_mmc_defconfig | 1 + configs/at91sam9n12ek_spiflash_defconfig | 3 + configs/at91sam9rlek_dataflash_defconfig | 3 + configs/at91sam9rlek_mmc_defconfig | 1 + configs/at91sam9x5ek_dataflash_defconfig | 3 + configs/at91sam9x5ek_mmc_defconfig | 1 + configs/at91sam9x5ek_spiflash_defconfig | 3 + configs/at91sam9xeek_dataflash_cs0_defconfig | 3 + configs/at91sam9xeek_dataflash_cs1_defconfig | 3 + configs/axm_defconfig | 1 + configs/brppt1_mmc_defconfig | 2 + configs/brppt1_nand_defconfig | 2 + configs/brppt1_spi_defconfig | 3 + configs/brxre1_defconfig | 2 + configs/chiliboard_defconfig | 2 + configs/cm_t335_defconfig | 2 + configs/cm_t35_defconfig | 1 + configs/cm_t43_defconfig | 3 + configs/cm_t54_defconfig | 2 + configs/corvus_defconfig | 1 + configs/draco_defconfig | 1 + configs/eco5pk_defconfig | 1 + configs/etamin_defconfig | 2 + configs/ethernut5_defconfig | 3 + .../gardena-smart-gateway-at91sam_defconfig | 4 + configs/gurnard_defconfig | 2 + configs/igep00x0_defconfig | 17 ++ configs/mcx_defconfig | 1 + configs/meesc_dataflash_defconfig | 3 + configs/meesc_defconfig | 1 + configs/mt_ventoux_defconfig | 1 + configs/omap3_overo_defconfig | 1 + configs/omap4_sdp4430_defconfig | 1 + configs/pengwyn_defconfig | 1 + configs/picosam9g45_defconfig | 1 + configs/pm9261_defconfig | 3 + configs/pm9263_defconfig | 3 + configs/pxm2_defconfig | 1 + configs/rastaban_defconfig | 1 + configs/rut_defconfig | 1 + configs/sama5d27_som1_ek_mmc1_defconfig | 1 + configs/sama5d27_som1_ek_mmc_defconfig | 1 + configs/sama5d2_icp_mmc_defconfig | 1 + configs/sama5d2_ptc_ek_mmc_defconfig | 1 + configs/sama5d2_xplained_emmc_defconfig | 1 + configs/sama5d2_xplained_mmc_defconfig | 1 + configs/sama5d2_xplained_spiflash_defconfig | 3 + configs/sama5d36ek_cmp_mmc_defconfig | 1 + configs/sama5d36ek_cmp_spiflash_defconfig | 3 + configs/sama5d3_xplained_mmc_defconfig | 1 + configs/sama5d3xek_mmc_defconfig | 1 + configs/sama5d3xek_spiflash_defconfig | 3 + configs/sama5d4_xplained_mmc_defconfig | 1 + configs/sama5d4_xplained_spiflash_defconfig | 3 + configs/sama5d4ek_mmc_defconfig | 1 + configs/sama5d4ek_spiflash_defconfig | 3 + configs/smartweb_defconfig | 1 + configs/snapper9260_defconfig | 2 + configs/snapper9g20_defconfig | 2 + configs/taurus_defconfig | 1 + configs/thuban_defconfig | 1 + configs/ti816x_evm_defconfig | 2 + configs/tricorder_defconfig | 2 + configs/tricorder_flash_defconfig | 1 + configs/twister_defconfig | 1 + configs/usb_a9263_dataflash_defconfig | 3 + configs/vinco_defconfig | 3 + configs/wb45n_defconfig | 1 + configs/wb50n_defconfig | 1 + drivers/mtd/ubi/Kconfig | 2 +- drivers/mtd/ubi/io.c | 2 + drivers/mtd/ubispl/ubispl.c | 215 +++++++++++++++++- drivers/mtd/ubispl/ubispl.h | 9 +- env/Kconfig | 24 +- env/ubi.c | 17 +- include/configs/am335x_evm.h | 3 -

[RFC][PATCH v4] Add support for SoM "VoCore2"
by Mauro Condarelli 29 Jan '20

29 Jan '20

Foreword: Patch sent as reference only, as it *still* does not work as expected. Most likely some cache misalignment is afoot (but I didn't change anything there). Symptoms are: * Dynamically loading a *different* version of U-Boot with: usb start; load usb 0:1 80200000 u-boot.bin; go 80200000 very often does not work. Workaround is: usb start; load usb 0:1 80200000 u-boot.bin; load usb 0:1 85000000 uImage; go 80200000 * I noticed a very strange behavior with Linux command line handling: U-Boot 2020.01-00646-g03de3f19fa (Jan 28 2020 - 22:56:42 +0100) CPU: MediaTek MT7628A ver:1 eco:2 Boot: DDR2, SPI-NOR 3-Byte Addr, CPU clock from XTAL Clock: CPU: 580MHz, Bus: 193MHz, XTAL: 40MHz Model: VoCore2 DRAM: 128 MiB WDT: Started with servicing (60s timeout) MMC: mmc@10130000: 0 Loading Environment from FAT...

[PATCH v6 02/10] lib: elf: Move the generic elf loading/validating functions to lib
by Keerthy 29 Jan '20

29 Jan '20

Move the generic elf loading/validating functions to lib/ so that they can be re-used and accessed by code existing outside cmd. While at it remove the duplicate static version of load_elf_image_phdr under arch/arm/mach-imx/imx_bootaux.c.

mmc init fails after soft reset on T1042
by Amarnath MB 28 Jan '20

28 Jan '20

Hi all, I working on a T1042RDB based custom board which has a 8GB eMMC (4bit mode) on board. I was able to successfully boot 2019.07 uboot on my board from NOR flash. After booting, mmcinfo command detects the on board eMMC and displays it's properties. But when I issue mmcinfo command after soft reset through reset command, it gives me mmc_init timeout error. After adding DEBUG and CONFIG_MMC_TRACE macros to my board header file, i came to know that the eMMC fails to respond to CMD 2. What can be the issue here? Can anyone guide me? Regards, Amarnath MB
