[PATCH 0/8]
by Patrick Delaunay 03 Mar '21

03 Mar '21

Serie proposed after analysis in [1], to correctly handle Domain Access Control Register (DACR) and activate the domain checking in MMU against the permission bits in the translation tables and avoids prefetching issue on ARMv7, as indicated in [1]. I propose a clean and general solution for ARMv7, when the LPAE is not activated; after this update, I revert the correction done for OMAP by the commit de63ac278cba ("ARM: mmu: Set domain permissions to client access") Tests on ARMv7 platform is requested before integration, so I think the target can be v2021.07 (next). The 2 first patch of the serie solve issues for stm32mp platform when dcache is activate in pre-reloc or in SPL.

U-Boot ECDSA Implementation Question
by Tim Romanski 03 Mar '21

03 Mar '21

Hello, I'm a current intern at Microsoft, and one of my priorities is to enable ECDSA for U-Boot image signing/verification. Simon mentioned someone is already working on ECC, it would be great to get synced up with related progress. For signing, I will likely replicate the existing approach of using the openssl library. I'm aware that signing happens on a host machine and verification happens during boot, which implies verification should have a custom implementation to avoid the openssl overhead in the U-Boot binary. My thoughts are to copy an ECC verification implementation from a well-tested widely-used open source project. I was wondering, is U-Boot's current RSA verification copied from another project? If so, how are security patches between the two copies of code usually handled? I'm thinking of deriving from the ECDSA implementation currently in the Linux kernel, though I'd also appreciate suggestions if there's a better/more widely tested & used implementation. All the best, Tim

[PATCH v3 1/1] env: sf: single function env_sf_save()
by Harry Waschkeit 03 Mar '21

03 Mar '21

Instead of implementing redundant environments in two very similar functions env_sf_save(), handle redundancy in one function, placing the few differences in appropriate pre-compiler sections depending on config option CONFIG_ENV_OFFSET_REDUND. Additionally, several checkpatch complaints were addressed. This patch is in preparation for adding support for env erase.

[PATCH v3 0/2] Add Gateworks Venice board support
by Tim Harvey 03 Mar '21

03 Mar '21

The Gateworks Venice product family consists of several boards based on the i.MX 8M Mini SoC. A challenge I've had with this is that the board model information is stored in an I2C based EEPROM that must be read to know what PMIC is on the board in order to adjust certain power rails before DRAM init is called. I found this to be a challenge in the SPL as the SPL does not free memory thus the conceprt of calling dm_uninit() followed by dm_init_and_scan() to change dt's live in the SPL runs out of memory. Therefore I can't rely on DT/DM within the SPL for things that may differ board to board.

[PATCH V4] ARM: imx: Include u-boot.img in u-boot-with-spl.imx if OF_SEPARATE=y
by Marek Vasut 03 Mar '21

03 Mar '21

The u-boot-with-spl.imx is a concatenation of SPL and u-boot.uim. The u-boot.uim is u-boot.bin wrapped in uImage. In case OF_SEPARATE is enabled, the u-boot.bin does not contain control DT for U-Boot, and so u-boot.uim does not contain the DT, and so u-boot-with-spl.imx does not contain the DT, and a system where u-boot-with-spl.imx is written to offset 1024B to the start of storage no longer boots, as it is missing DT. In case OF_SEPARATE is enabled, u-boot.img contains both u-boot.bin and the necessary DTs. Therefore, use u-boot.img instead of u-boot.uim to generate u-boot-with-spl.imx when OF_SEPARATE is enabled.
