treewide: change email links from mailman to patch.msgid.link with message-id

2026-07-03T20:41:14Z

In preparation of the migration of the mailman mailing-list currently hosted on the denx.de infrastructure, migrate the links in the code, comments and documentation to https://patch.msgid.link to be future proof and always link to the expected content data and uses the message-id in the URL which will help find the appropriate e-mail in the future.

p2041rdb: use the upstream device tree

2026-05-15T11:28:30Z

Switch to the upstream device tree, which already includes the UART nodes we need for the DM. We also need to increase malloc area before relocation otherwise you'll get the following error and the board panics: DRAM: Initializing....using SPD alloc space exhausted ptr 414 limit 400 Signed-off-by: Michael Walle Signed-off-by: Peng Fan

caam: don't write memory at 0 on PPC

2026-05-15T11:28:29Z

For non-secure boot environments pamu_init() isn't called but the CAAM will still call sec_config_pamu_table() -> config_pamu() which then uses an uninitialized ppaact variable. In fact, that variable is initialized with 0, so the config_pamu() will happily assume the structure is there and will operate on that memory. Call pamu_init() in the non-secure boot case, too.

powerpc: fix dead default for SYS_L3_SIZE

2026-05-06T02:28:35Z

The 'default ... if SYS_L3_SIZE_512KB' statement is written twice, making the second instance dead code. Based on the context, I believe the author of the code intended to set a default value of '1048576' when SYS_L3_SIZE_1024KB is set. This dead code was detected by kconfirm, a static analysis tool for Kconfig. Fixes: b85d75951fe ("powerpc: Migrate SYS_L3_SIZE to Kconfig") Signed-off-by: Julian Braha Signed-off-by: Peng Fan

sata: Rework the CMD_SATA and SATA symbols

2026-04-03T18:06:14Z

Today we typically enable CMD_SATA in order to have the SATA functionality itself enabled, despite there being a clean split between the two symbols. This in turn leads to potential configuration problems. Split things so that SATA continues to be separate and not CMD_SATA instead depends, functionally, on AHCI being enabled. To do all of this: - Have X86 select AHCI directly rather than "default y" it later. - Make CMD_SATA be a default y option, given the split of platforms that enabled SATA and did, or did not, enable CMD_SATA. - Change "imply CMD_SATA" to "imply SATA" - Correct TARGET_VEXPRESS64_JUNO because you cannot select SATA_SIL without PCI (and in turn, SATA is needed for SATA_SIL). - Update a number of defconfigs to have no functional change.

powerpc/mpc83xx: Move alignment padding into __u_boot_list section

2026-04-02T23:41:02Z

u-boot-dtb.bin is built by concatenating u-boot-nodtb.bin and u-boot.dtb. u-boot-nodtb.bin, in turn, is generated by objcopy'ing the contents of u-boot (U-Boot in ELF format) into a raw file. In order to find the bundled FDT (u-boot.dtb), the code in lib/fdtdec.c uses the _end symbol. Platform-specific linker scripts ensure that _end is 8-byte aligned, which is required by libfdt. For the PowerPC MPC83xx platform, the ALIGN(8) directive was outside a section, with the unfortunate effect that the potentially generated padding bytes would not be copied by objcopy. This resulted in a discrepancy between the _end symbol on the one hand, and the size of u-boot-nodtb.bin and thus the starting location of the actual FDT on the other side. Under these conditions, the FDT could not be found and boot would fail early. This commit fixes it by moving the ALIGN(8) into the __u_boot_list section, which is non-empty and thus copied into u-boot-nodtb.bin. Signed-off-by: J. Neuschäfer Reviewed-by: Tom Rini

core: Rework REGMAP symbols implementation

2026-03-30T22:59:35Z

As exposed by "make randconfig", we have an issue with the dependencies for REGMAP (and xPL variants). As this is a library function, it should always be selected and not depended on by other functionality. This is largely done correctly today, so just correct the few outliers.

powerpc: Call bootm_final()

2026-03-18T19:17:34Z

Replace the open-coded bootstage_fdt_add_report() and bootstage_report() with a call to bootm_final(). This also adds the "Starting kernel" message, board_quiesce_devices() and dm_remove_devices_active() which were not previously called on PowerPC. Signed-off-by: Simon Glass

board: nxp: Rename board directory from board/freescale to board/nxp

2026-01-28T06:26:50Z

This patch renames the board directory from board/freescale to board/nxp because NXP now provides Board Support Packages (BSPs) and tools for the former Freescale i.MX and other i.MX products. All relevant references have been updated accordingly. This change does not affect functionality. Signed-off-by: Alice Guo Reviewed-by: Fabio Estevam
