Using USB Mass Storage on AM335X
by Otavio Salvador 02 Nov '20

02 Nov '20

Hi, I am working on porting mainline U-Boot to a custom AM335X board that only has eMMC as the boot medium. I can load U-Boot via serial boot and flash MLO and u-boot.img into the eMMC using DFU. Then the board boots successfully via eMMC. Now I want to run the "ums" command to be able to mount the eMMC on the host. The problem I am getting is that when I select CONFIG_CMD_USB_MASS_STORAGE=y the board no longer boots. Does anyone know why selecting CONFIG_CMD_USB_MASS_STORAGE=y causes the board to not boot anymore? Thanks for your help -- Otavio Salvador O.S.

[PATCH v2 0/9] ARM: dts: at91: DTC 1.6.0+ warning fixes
by Eugen Hristev 02 Nov '20

02 Nov '20

This series fixes warnings when moving to DTC 1.6.0+. Anyone who still has these boards and is willing to test them, it's appreciated. I do not have any of the boards listed here at the moment. Thanks !

[PATCH v4 0/3] env: Access Environment in SPI flashes before relocation
by Heiko Schocher 02 Nov '20

02 Nov '20

Add the possibility to access Environment stored in SPI NOR Flash before relocation. This is used in DM/DTS rework for the aristainetos boards. There mutliple DTS are packed into a FIT image and through a variable in the Environment the correct DTS will be selected. For this we need very early access to the Environment. Also may this is good for selecting the console baudrate again through Environment which I think currently does not work for any board based on DM/DTS and with Environment in SPI NOR flash. Add this to aristainetos board, as aristainetos DM board updates are now in mainline. travis build: https://travis-ci.org/github/hsdenx/u-boot-test/builds/733559949 Changes in v4: - rebased to current master 5dcf7cc590 Changes in v3: - env_sf_init_early() always return 0 now. If we do not return 0 in this function, env_set_inited() never get called, which has the consequence that env_load/save/erase never work, because they check if the init bit is set. - add comment from Simon Glass - add missing function comments - use if(IS_ENABLED...) - drop extra brackets - let env_sf_init() decide, which function to call add comment that it is necessary to return env_sf_init() with 0. - new in v3 as aristainetos board DM changes are in mainline now Changes in v2: - patch "env: split env_import_redund into 2 functions" is new in version 2. Idea is to not duplicate too much code as Simon suggested.

[PATCH 0/8] Pin control support for RZ/G2[HN]
by Biju Das 01 Nov '20

01 Nov '20

This patch series adds pin control support for RZ/G2[HN] SoC's. Also added pinctrl optimization for RZ/G2[HMN] SoC's. This patches are based on u-boot-sh/next. + Geert The last 3 patches in this series are RFC, which aims to optimize pinctrl size for RCar SoC 's( The u-boot size is reduced from 1025221 to 964365 bytes) The saving is around ~60K. Please share your comments. Note:- 1) I haven't tested the RFC changes on r-car boards due to unavailability of the boards. 2) Optimization is based on the fact that some pins are not enabled in board dts(like DRIF,MSIOF etc..) u-boot-sh\next -------------- $ size drivers/pinctrl/renesas/*.o text data bss dec hex filename 151332 288 1 151621 25045 drivers/pinctrl/renesas/built-in.o 3811 288 1 4100 1004 drivers/pinctrl/renesas/pfc.o 48123 0 0 48123 bbfb drivers/pinctrl/renesas/pfc-r8a7795.o 47939 0 0 47939 bb43 drivers/pinctrl/renesas/pfc-r8a77965.o 47751 0 0 47751 ba87 drivers/pinctrl/renesas/pfc-r8a7796.o $ ls -al u-boot.bin -rw-r--r-- 1 biju biju 1025221 Oct 28 08:48 u-boot.bin $ size u-boot text data bss dec hex filename 942336 36208 71632 1050176 100640 u-boot After Applying patch 1-5 ---------------------- $ size drivers/pinctrl/renesas/*.o text data bss dec hex filename 151868 288 1 152157 2525d drivers/pinctrl/renesas/built-in.o 3811 288 1 4100 1004 drivers/pinctrl/renesas/pfc.o 48375 0 0 48375 bcf7 drivers/pinctrl/renesas/pfc-r8a7795.o 48191 0 0 48191 bc3f drivers/pinctrl/renesas/pfc-r8a77965.o 47751 0 0 47751 ba87 drivers/pinctrl/renesas/pfc-r8a7796.o $ ls -al u-boot.bin -rw-r--r-- 1 biju biju 1026621 Oct 28 08:42 u-boot.bin $ size u-boot text data bss dec hex filename 943732 36208 71632 1051572 100bb4 u-boot After applying RFC patches -------------------------- $ size drivers/pinctrl/renesas/*.o text data bss dec hex filename 125310 288 1 125599 1ea9f drivers/pinctrl/renesas/built-in.o 3811 288 1 4100 1004 drivers/pinctrl/renesas/pfc.o 40157 0 0 40157 9cdd drivers/pinctrl/renesas/pfc-r8a7795.o 39973 0 0 39973 9c25 drivers/pinctrl/renesas/pfc-r8a77965.o 39533 0 0 39533 9a6d drivers/pinctrl/renesas/pfc-r8a7796.o $ ls -al u-boot.bin -rw-r--r-- 1 biju biju 964365 Oct 28 09:32 u-boot.bin $ size u-boot text data bss dec hex filename 881478 36208 71632 989318 f1886 u-boot Biju Das (8): pinctrl: renesas: r8a77965: Add R8A774B1 PFC support pinctrl: renesas: r8a77951: Add R8A774E1 PFC support pinctrl: renesas: r8a7796: Optimize pinctrl image size for R8A774A1 pinctrl: renesas: r8a77965: Optimize pinctrl image size for R8A774B1 pinctrl: renesas: r8a7795: Optimize pinctrl image size for R8A774E1 pinctrl: renesas: r8a7796: Optimize pinctrl image size for R8A7796 pinctrl: renesas: r8a77965: Optimize pinctrl image size for R8A77965 pinctrl: renesas: r8a7795: Optimize pinctrl image size for R8A7795 arch/arm/mach-rmobile/Kconfig.64 | 2 + drivers/pinctrl/renesas/Kconfig | 26 + drivers/pinctrl/renesas/Makefile | 2 + drivers/pinctrl/renesas/pfc-r8a7795.c | 939 ++++++++++++++----------- drivers/pinctrl/renesas/pfc-r8a7796.c | 36 + drivers/pinctrl/renesas/pfc-r8a77965.c | 931 +++++++++++++----------- drivers/pinctrl/renesas/pfc.c | 22 + drivers/pinctrl/renesas/sh_pfc.h | 2 + 8 files changed, 1146 insertions(+), 814 deletions(-) -- 2.17.1
