[PATCH v2] binman: Get futility by building it
by Simon Glass 14 Sep '22

14 Sep '22

A binary download is not great, since it depends on libraries being present in the system. Build futility from source instead.

[PATCH v2 0/3] Support UEFI SPI I/O protocol
by Paul Barker 14 Sep '22

14 Sep '22

These patches add support for the UEFI SPI I/O protocol defined in the UEFI Platform Initialization (PI) Specification, Version 1.7 Errata A (April 2020). This allows a UEFI application to interact with devices on the SPI bus. The code here is self-contained and easy to enable/disable at compile time. Compilation testing with am335x_evm_defconfig shows that the size of u-boot.img increases by less than 2kB when CONFIG_EFI_SPI_PROTOCOL is enabled. Changes since v1: * Do not enable CONFIG_EFI_SPI_PROTOCOL by default. * Add efi_seltest unit test. * Mark functions with EFIAPI where necessary. * Handle debug_transaction argument to efi_spi_io_transaction(). * Handle a value of zero for target->max_read_size & target->max_write_size. * Probe inactive SPI devices when initializing the EFI SPI protocol to ensure that dev_get_parent_priv() returns valid data and the exported devices are ready to use. * Skip emulated SPI peripherals. These appear as duplicates within the list of devices on the bus when using the sandbox SPI drivers. * Make most printf statements debug only.

imx8mq allocation issue
by Heiko Thiery 14 Sep '22

14 Sep '22

HI, I think on the imx8mq platform we have a problem with the introduction of the clock driver. I tried to debug the problem that the pitx-imx8m board was not able to start for some time. I was wondering why the pitx-im8m doesn't work anymore although the imx8mq_evk is running. So I switched to the imx8mq_evk for counter testing. As I already figured out in [1] also the imx8mq_evk is not able to start properly. On the EVK I enabled the DEBUG_UART and see the outputs below. I suspect all imx8mq boards have this problem.

[PATCH 0/2] sunxi: defconfig: use Kconfig defaults
by Andre Przywara 14 Sep '22

14 Sep '22

[Resending just to the mailing list forgotten on the first post] Some recent patches from Tom (thanks for that!) were converting some configuration options from header files to Kconfig symbols. For sunxi, this moved their value definition into every *board* defconfig, although they are actual per-SoC choices. Make this obvious by defining per-SoC default values in the Kconfig stanza, and removing the now redundant explicit defconfig definitions. Apart from using the opportunity to upgrading the uncompressed arm64 kernel size to 64MB, this does not change configs otherwise. Patch 1 adds the default definitions, patch 2 removes the defconfig definitions.

[v5 00/14] Add ASPEED SPI controller driver
by Chin-Ting Kuo 13 Sep '22

13 Sep '22

This patch series aims to porting ASPEED FMC/SPI memory controller driver with spi-mem interface. spi-mem dirmap framework is also synchronized from Linux. These patches have been verified on AST2600, AST2500 and AST2400 EVBs. Changes in v2: - Separate defconfig files from the SPI driver patch. - Use "if (CONFIG_IS_ENABLED(SPI_DIRMAP))" to wrap spi_dirmap related functions. - Add Winbond w25q512jv flash ID. Changes in v3: - Get AHB bus clock frequency from the function parameter. - Fix a grammatical error in spi-mem.h. Changes in v4: - Fix bug when SPI_NOR_4B_OPCODES flag is set. Changes in v5: - Separate main ASPEED SPI driver patch into different parts. * basic support. * decoded range adjustment. * clock settings. - Add support customized decoded range. - Add AST2400 platform support.

Ftdoverlays documentation
by Edoardo Tomelleri 13 Sep '22

13 Sep '22

Hello, I can not find u-boot documentation for the fdtoverlays option in extlinux.conf files, here: https://u-boot.readthedocs.io/en/latest/develop/distro.html?highlight=extli… (is it supported? I've found that in January 2021 a related patch was accepted) The docs refer to the boot loader spec (https://systemd.io/BOOT_LOADER_SPECIFICATION/), where keys devicetree and devicetree-overlay are supported. Right now, I understand that u-boot supports keywords both 'fdt' and 'devicetree' with the same meaning, and 'fdtoverlays', but not 'devicetree-overlay', is this correct? Thanks, Edoardo

[PATCH] doc: dm: Fix typo

That's most probably a typo, because driver model design documents seem to be from 2012 and there is no 2010.01 release.
