[PATCH v6 0/9] Integrate EFI capsule tasks into u-boot's build flow
by Sughosh Ganu 04 Aug '23

04 Aug '23

This patchset aims to bring two capsule related tasks under the u-boot build flow. One is the embedding of the public key into the platform's dtb. The public key is in the form of an EFI Signature List(ESL) file and is used for capsule authentication. This is being achieved by adding the signature node containing the capsule public key in the architecture's u-boot.dtsi file. Currently, the u-boot.dtsi file has been added for the sandbox and arm architectures. The path to the ESL file is being provided through a Kconfig symbol(CONFIG_EFI_CAPSULE_ESL_FILE). Changes have also been made to the test flow so that the keys used for signing the capsule, and the ESL file, are generated prior to invoking the u-boot's build, which enables embedding the ESL file into the dtb as part of the u-boot build. The other task is related to generation of capsules. The capsules can be generated as part of u-boot build, and this is being achieved through binman, by adding a capsule entry type. The capsules can be generated by specifying the capsule parameters as properties under the capsule entry node. Changes have also been made to the efi capsule update feature testing setup on the sandbox variants. Currently, the capsule files and the public key ESL file are generated after u-boot has been built. This logic has been changed so that the capsule input files along with the keys needed for capsule signing and authentication are generated prior to initiation of the u-boot build. The placement of all the files needed for generation of capsules is under the test/py/tests/test_efi_capsule/test_files/ directory. The document has been updated to reflect the above changes. Changes since V5: This series drops the changes for generating capsules by reading the params from a config file. This was suggested by Simon Glass. The config file changes would be submitted separately once these changes get merged. * Get rid of the logic of keeping the files under the /tmp/capsules/ directory from earlier versions. * New patch which introduces the input files and certs needed for EFI capsule update testing in the tree. * The capsule input files and certs are put under the test/py/tests/test_efi_capsule/test_files/ directory. * Add support for the oemflag parameter used in FWU A/B updates. This was missed in the earlier version. * Use a single function, generate_capsule in the mkeficapsule bintool, instead of the multiple functions in earlier version. * Remove the logic for generating capsules from config file as suggested by Simon. * Use required_props for image index and GUID parameters. * Use a subnode for the capsule payload instead of using a filename for the payload, as suggested by Simon. * Add a capsule generation test with oemflag parameter being passed. * Remove the documentation for generating the capsule through config file, as that functionality is not added through this series. * Use the public key ESL file from the tree instead of the /tmp/capsules/ directory being used in previous version. * Use the public key ESL file and other input files from the tree instead of the /tmp/capsules/ directory being used in previous version. * Use macros for other input files and certs.

[PATCH] efi_loader: Increase default variable store size to 32K

Debian's arm64 UEFI Secure Boot shim makes the EFI variable store run out of space while mirroring its MOK database to variables. This can be observed in QEMU like so: $ tools/buildman/buildman -o build/qemu_arm64 --boards=qemu_arm64 -w $ cd build/qemu_arm64 $ curl -L -o debian.iso \ https://cdimage.debian.org/debian-cd/current/arm64/iso-cd/debian-12.0.0-arm… $ qemu-system-aarch64 \ -nographic -bios u-boot.bin \ -machine virt -cpu cortex-a53 -m 1G -smp 2 \ -drive if=virtio,file=debian.iso,index=0,format=raw,readonly=on,media=cdrom [...] => # interrupt autoboot => env set -e -bs -nv -rt -guid 605dab50-e046-4300-abb6-3dd810dd8b23 SHIM_VERBOSE 1 => boot [...] mok.c:296:mirror_one_esl() SetVariable("MokListXRT43", ... varsz=0x4C) = Out of Resources mok.c:452:mirror_mok_db() esd:0x7DB92D20 adj:0x30 Failed to set MokListXRT: Out of Resources mok.c:767:mirror_one_mok_variable() mirror_mok_db("MokListXRT", datasz=17328) returned Out of Resources mok.c:812:mirror_one_mok_variable() returning Out of Resources Could not create MokListXRT: Out of Resources [...] Welcome to GRUB! This would normally be fine as shim would continue to run grubaa64.efi, but shim's error handling code for this case has a bug [1] that causes a synchronous abort on at least chromebook_kevin (but apparently not on QEMU arm64). Double the default variable store size so the variables fit. There is a note about this value matching PcdFlashNvStorageVariableSize when EFI_MM_COMM_TEE is enabled, so keep the old default in that case.

[PATCH v5 0/3] board: toradex: add verdin am62 support
by Marcel Ziswiler 04 Aug '23

04 Aug '23

From: Marcel Ziswiler <marcel.ziswiler(a)toradex.com> This series adds initial support for the Toradex Verdin AM62 SoM [1]. The first commit adds resp. PID4s to the ConfigBlock, the second one fixes an early clocking issue confirmed to be a weird bug in TI's scripting. And last but not least support for the Toradex Verdin AM62 is added. Azure CI all passed [2]. Thanks! [1] https://www.toradex.com/computer-on-modules/verdin-arm-family/ti-am62 [2] https://dev.azure.com/u-boot/u-boot/_build/results?buildId=6792&view=results Changes in v5: - Fix doc/board/toradex/verdin-am62.rst title underline being too short. - Add verdin-am62 to doc/board/toradex/index.rst. Thanks to Emanuele having run this series on the azure CI to find out. - Update U-Boot output in doc/board/toradex/verdin-am62.rst to latest. - State that the device trees were taken straight from Linux v6.5-rc1. - Remove k3-am625-verdin-wifi-dev-binman.dtsi include from r5 dts. - Remove memory@ and reserved-memory nodes. - Simplify sa_secproxy and esm nodes. - Get rid of ifdef zeros around usb stuff in device trees. - Re-work doc/board/toradex/verdin-am62.rst in a more re-usable way. Thanks to Nishanth for pointing those differences out as compared to arch/arm/dts/k3-am625-r5-sk.dts and his suggestions on the rst stuff. Changes in v4: - Re-based on top of master with recent binman integration, mac_efuse, cpsw-phy-sel and mdio clean-up and dtsi bump from linux v6.5-rc1. - Verdin AM62 binman enablement and further clean-up after re-base. - Removed all ifdefs from DTs now with bumped Linux dtsi. - Avoid relocated U-Boot and DT reserved-memory clash. - Enable of_system_setup. Changes in v3: - Add Verdin AM62 launch configuration SKUs as well. - Integrate our recent find of CTRL_SLEEP_MOCI# needing to be driven from A53 SPL as it may be used to control some power-rails on the carrier board. E.g. on the Yavia carrier board it is needed to power the I2C EEPROM on the carrier board. - Improve boot environment in R5 SPL vs. A53. - Integrate launch configuration SKUs to Wi-Fi handling. - Re-sync device trees from Linux kernel v6.5-rc1. - Add warning if memory is less than expected. Changes in v2: - Add Bryan's reviewed-by tag. Thanks! - Use 1.2 GHz rather than 1.25 GHz A53 clock as on the EVM/SK. - Also add power-domain 166 as on the EVM/SK. - Get rid of main_bcdma and main_pktdma as not required in R5 SPL. - Get rid of all bootph-pre-ram in Ethernet and SDHC1 aka SD card related pinctrls as not required in any SPL. - Enable CONFIG_TI_SECURE_DEVICE by default as Non-HS devices will continue to boot due to runtime device type detection. - Disable FAT and SPI support as not required in R5 SPL. - Also enable CONFIG_SPL_MMC_HS200_SUPPORT in R5 SPL. - Enable CONFIG_LEGACY_IMAGE_FORMAT to allow sourcing unsigned script images e.g. like our current boot scripts. - Increase CONFIG_SYS_BOOTM_LEN to 64 MB to allow booting bigger compressed images as e.g. in the Toradex Easy Installer case. - Change memory configurations to operate at temperatures of up to 95 degrees celsius. - Increase CONFIG_SYS_MAXARGS from default 16 to 64. - Enable CONFIG_CMD_REMOTEPROC, CONFIG_SPL_DM_GPIO_LOOKUP_LABEL and CONFIG_SPL_I2C_EEPROM. - For R5 SPL increase CONFIG_SPL_STACK_R_MALLOC_SIMPLE_LEN to 0x140000, enable CONFIG_SPL_I2C, CONFIG_DM_I2C and CONFIG_SYS_I2C_OMAP24XX and savedefconfig got rid of CONFIG_SPL_FIT_IMAGE_POST_PROCESS.
