[PATCH 01/17] miiphy: Introduce mdio_init()
by Marek Vasut 27 Jan '25

[PATCH v2 0/4] Enable bloblist support on Vexpress64
by Harrison Mutai 27 Jan '25

27 Jan '25

This series of patches enhances the vexpress64 platform by enabling bloblist support. It also introduces support for CONFIG_BLOBLIST_PASSAGE. This is necessary to boot vexpress64 and other boards without manually specifying a fixed address and size for the bloblist. After this change, all the bloblist init modes are supported (i.e., fixed, alloc, passage) and Vexpress64 boots with CONFIG_BLOBLIST_PASSAGE. Changes in v2: * The commit body for the typo fix was expanded. * The default BLOBLIST_RELOC_SIZE was removed when CONFIG_BLOBLIST_PASSAGE is enabled, the relocation size depends on the size of bloblist received.

[PATCH] net: fsl_enetc: Enable optional ENETREF clock on i.MX95
by Marek Vasut 27 Jan '25

27 Jan '25

The ENETCv4 port DT nodes on i.MX95 may contain optional clock phandle to IMX95_CLK_ENETREF "ref" clock. These "ref" clock must be enabled for the ethernet to work. These "ref" clock are enabled after cold boot, but when the system booted Linux and rebooted, those "ref" clock might have been disabled in the process, which would make ethernet inoperable after reboot. Make sure those "ref" clock are always correctly enabled.

[PATCH 01/10] pinctrl: imx: Push imx_pinctrl_ops into drivers and staticize

27 Jan '25

Move imx_pinctrl_ops into drivers and staticize. This is preparatory patch for follow up pinctrl drivers which will not use this variant of imx_pinctrl_ops content.

[PATCH v3 0/5] Add pmem node for preserving distro ISO's
by Sughosh Ganu 27 Jan '25

27 Jan '25

When installing a distro via EFI HTTP boot some OS installers expect the .iso image to be preserved and treat it as a "CDROM" to install packages. This is problematic in EFI, since U-Boot mounts the image, starts the installer, and eventually calls ExitBootServices. At that point the image U-Boot mounted disappears. Some distros don't care and download the missing packages from a web archive, while others halt the installation complaining they can't find certain packages. If the firmware uses ACPI, this is supported by using NFIT which provides NVDIMM ramdisks to the OS and preserves the image. We don't have anything in place for Device Trees though. Since DT supports persistent memory nodes (pmem) use those and preserve the .iso for installers. The issue can be reproduced by attempting an EFI HTTP boot with Ubuntu live server ISO, or a Rocky Linux ISO. The installation would fail with the failure to locate certain packages. The earlier version had aligned the addition of pmem nodes with the EFI HTTP boot feature. This has been changed, based on a review comment from Heinrich to instead be done by looping through the memory based blkmamp devices. Changes since V2: * Fix a checkpatch error for putting a blank line after a function * Use blkmap device based scanning for adding the pmem nodes Ilias Apalodimas (2): efi_loader: add a function to remove memory from the EFI map efi_loader: preserve installer images in pmem Masahisa Kojima (1): fdt: add support for adding pmem nodes Sughosh Ganu (2): blkmap: store type of blkmap device in corresponding structure blkmap: add pmem nodes for blkmap mem mapping devices boot/fdt_support.c | 40 ++++++++++++- boot/image-fdt.c | 9 +++ cmd/blkmap.c | 16 ++++-- drivers/block/blkmap.c | 90 +++-------------------------- drivers/block/blkmap_helper.c | 47 +++++++++++++++- include/blkmap.h | 103 +++++++++++++++++++++++++++++++++- include/efi_loader.h | 11 ++-- include/fdt_support.h | 13 +++++ lib/efi_loader/efi_bootmgr.c | 22 ++++++-- lib/efi_loader/efi_memory.c | 51 ++++++++++++----- lib/lmb.c | 4 +- test/dm/blkmap.c | 16 +++--- 12 files changed, 302 insertions(+), 120 deletions(-) -- 2.34.1

[PATCH 1/8] cyclic: Prevent corruption of cyclic list on reassignment
by Marek Vasut 27 Jan '25

27 Jan '25

Make cyclic_register() return error code, 0 in case of success, -EALREADY in case the called attempts to re-register already registered struct cyclic_info. The re-registration would lead to corruption of gd->cyclic_list because the re-registration would memset() one of its nodes, prevent that. Unregister only initialized struct cyclic_info.

[PATCH 1/1] examples/api: improve determination of LOAD_ADDR
by Heinrich Schuchardt 27 Jan '25

27 Jan '25

The current load address for the 'demo' binary does not work for qemu_arm_defconfig. The suitability of an address to load an ELF binary and run it does not only depend on the architecture but also on the memory layout of the board. On most boards we can assume that 8 MiB of memory is available above $loadaddr. So $loadaddr + 0x400000 should work there.
