[PATCH] ARM: dts: stm32: Auto-detect second MAC on STM32MP15xx DH electronics DHCOM
by Marek Vasut 14 Jun '24

14 Jun '24

Test whether this system is compatible with STM32MP15xx DHCOM SoM, if so, test whether R292 pull up is populated on pin PC3, which is an indication that the second MAC chip, KS8851-16MLL, is populated. Use this information to patch 'status' DT property into the second ethernet MAC DT node and enable/disable the MAC on systems where the chip is/isn't populated respectively. Use spl_perform_fixups() to patch the U-Boot proper DT from SPL and ft_board_setup() to patch Linux DT from U-Boot proper. This way both software components are configured the same way.

[PATCH] ARM: dts: stm32: Add generic SoM compatible to STM32MP15xx DH electronics DHSOM
by Marek Vasut 14 Jun '24

14 Jun '24

Add generic SoM compatible string into machine compatible string for all STM32MP15xx based DH electronics DHSOM. This way, common board code can match on this compatible. No functional change.

silent u-boot not working
by Jonas Kvinge 14 Jun '24

14 Jun '24

Hi, I'm running openSUSE Tumbleweed on an RPI CM4, I'm trying to silence u- boot boot messages, with the default configuration there is an u-boot logo on the top right corner and boot text, I'd like to get rid of the logo and all text if possible. The keyboard is not working before the Linux kernel is loaded, so I can not interrupt u-boot and enter any commands, so where should I put "set env silent 1"? I've followed the guide on https://github.com/ARM-software/u-boot/blob/master/doc/README.silent I have built u-boot from source using `make rpi_4_defconfig` configuration modified the configuration with make menuconfig, and verified this in .config before builing. CONFIG_SILENT_CONSOLE=y CONFIG_SILENT_U_BOOT_ONLY=y CONFIG_SILENT_CONSOLE_UPDATE_ON_SET=y CONFIG_SILENT_CONSOLE_UPDATE_ON_RELOC=y CONFIG_SILENT_CONSOLE_UNTIL_ENV=y Copied the binary to /boot/efi/u-boot.bin and /boot/vc/u-boot.bin I've also tried to define CONFIG_EXTRA_ENV_SETTINGS in include/configs/rpi.h according to: https://stackoverflow.com/questions/34356844/how-to-disable-serial-consolen… and rebuilt and copied to binary again, still not working. The text and logo is still present during boot, what am I doing wrong here? Jonas

[PATCH v2] stm32mp: Reserve OPTEE area in EFI memory map
by Patrice Chotard 14 Jun '24

14 Jun '24

Since commit 7b78d6438a2b3 ("efi_loader: Reserve unaccessible memory") memory region above ram_top is tagged in EFI memory map as EFI_BOOT_SERVICES_DATA. In case of STM32MP1/STM32MP13 platforms, above ram_top, there is one reserved-memory region tagged "no-map" dedicated to OP-TEE : _ addr=de000000 size=2000000 for stm32mp157x-dkx and stm32mp135f-dk _ addr=fe000000 size=2000000 for stm32mp157c-ev1 Before booting kernel, EFI memory map is first built, the OPTEE region is tagged as EFI_BOOT_SERVICES_DATA and when reserving LMB, the tag LMB_NONE is used. Then after, the LMB are completed by boot_fdt_add_mem_rsv_regions() which try to add again the same OPTEE region (addr=de000000 size=2000000 in case of stm32mp157x-dkx / stm32mp135f-dk or addr=fe000000 size=2000000 in case for stm2mp157c-ev1) but now with LMB_NOMAP tag which produces the following error message : _ for stm32mp157x-dkx / stm32mp135f-dk : "ERROR: reserving fdt memory region failed (addr=de000000 size=2000000 flags=4)" _ for stm32mp157c-ev1 : "ERROR: reserving fdt memory region failed (addr=fe000000 size=2000000 flags=4)" To avoid this, OPTEE area shouldn't be used by EFI, so we need to mark it as reserved.
