would it be feasible to enable GPT support for clearfrog at source?
by ѽ҉ᶬḳ℠ 03 Jan '20

03 Jan '20

The source conf for clearfrog appears absent of GPT support albeit there should not be space concern for that target, if that is the reason. Owning such device I took me some effort and time to figure out why the device would not boot from a GPT partition but only from legacy MBR. Thus I would appreciate if GPT support could be implement for this target. As far as I can comprehend from the source code it would require + CONFIG_CMD_GPT + CONFIG_PARTITION_UUIDS but maybe there is more?

[PATCH v5 0/7] rockchip: Add Binman support
by Jagan Teki 03 Jan '20

03 Jan '20

This is v5 set for Binman support in rockchip, [1] here is previous patchset. This series add single boot image with binman for arm32 and pad_cat for arm64 rockchip platforms both TPL + SPL and SPL-alone targets. Changes for v5: - collect kever review tag - drop idbloader.img from clean target Changes for v4: - support all rockchip platforms - add new patches for dtsi changes - update documentation - format proper commit message - rebase on master Changes for v3: - rebase on master - add binman for rk3288, rk3328, rk3368, rk3399 - added rst documentation for rockchip Changes for v2: - Add few clean target patches - update bl31.elf env handling code, with logging - support puma itb, via BL31 and PMUM0 env - enable BUILD_TARGET for ROCKCHIP_RK3399 [1] https://patchwork.ozlabs.org/cover/1182449/ Any inputs?

[U-Boot] [PATCH 0/4] omapl138_lcdk: fix MMC boot
by Bartosz Golaszewski 03 Jan '20

03 Jan '20

From: Bartosz Golaszewski <bgolaszewski(a)baylibre.com> Booting from MMC on omapl138-lcdk is currently broken after we enabled driver-model in SPL. While I know what's wrong - the bind() callback not being called - I can't for the life of me figure out how to fix it. I'm still working on proper changes, but for now, I'd like to propose this series which fixes MMC boot with a workaround in which we call mmc_boot() manually from probe. First two patches drop some legacy code that's no longer needed. The third patch adds a U_BOOT_DEVICE() for mmc as we don't yet have full DT support (also in-progress). The last patch adds the workaround to the davinci mmc driver. This series depends on Adam Ford's patch increasing the pre-reloc malloc pool.

Problems with rock64 after enabling CONFIG_MISC_INIT_R
by Peter Hjalmarsson 03 Jan '20

03 Jan '20

Hi, After the following commit I have problems with my rock64 SBCs: commit 893b4d0df4deb802480aeb606d3b0aa2d0ea27d8 Author: Ben Wolsieffer <benwolsieffer(a)gmail.com> Date: Tue Dec 3 00:24:31 2019 -0500 rockchip: rk3328: rock64: enable CONFIG_MISC_INIT_R This commit in current form results in identical cpuid and MAC-address for my rock64 boards, and thus creates problems. Please revert this as it seems like it this is due to missing code. What creates this problem? The rock64 config currently does not configure ROCKCHIP_EFUSE or ROCKCHIP_OTP. The code tries to use rockchip_cpuid_from_efuse from ./arch/arm/mach-rockchip/misc.c to get cpuid. When none of the above is configured, this function is a no-op returning only 0. Setting any of them, and the boot stops with: --- rockchip_cpuid_from_efuse() rockchip_cpuid_from_efuse: could not find efuse device initcall sequence 00000000fefc0d58 failed at call 0000000000202dac (err=-1) ### ERROR ### Please RESET the board ### --- So my guess is that there is missing code to properly read cpuid from EFUSE on rk3328, and until that is fixed so we can enable ROCKCHIP_EFUSE, CONFIG_MISC_INIT_R needs to be disabled in the default configuration for the rock64 board. Best Regards, Peter Hjalmarsson

[PATCH v2] riscv: Add option to print registers on exception
by Sean Anderson 03 Jan '20

03 Jan '20

When debugging, it can be helpful to see more information about an unhandled exception. This patch adds an option to view the registers at the time of the trap, similar to the linux output on a kernel panic.

[PATCH v1] colibri_imx7: disable HAB and CAAM support
by Igor Opaniuk 03 Jan '20

From: Igor Opaniuk <igor.opaniuk(a)toradex.com> Currently Colibri iMX7 NAND version doesn't boot at all with HABv4 support enabled. If CSF section is included in the final imx binary, BootROM every time switches to usb recovery mode. However eMMC version of the same SoM works without any issues.
