p2041rdb: use the upstream device tree

2026-05-15T11:28:30+00:00

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

caam: don't write memory at 0 on PPC

2026-05-15T11:28:29+00:00

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

2026-05-06T02:28:35+00:00

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.

sata: Rework the CMD_SATA and SATA symbols

2026-04-03T18:06:14+00:00

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

2026-04-02T23:41:02+00:00

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.

core: Rework REGMAP symbols implementation

2026-03-30T22:59:35+00:00

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()

2026-03-18T19:17:34+00:00

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.

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

2026-01-28T06:26:50+00:00

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.

powerpc: Update linker scripts to ensure appended device tree is aligned

2026-01-20T18:07:20+00:00

With commit 0535e46d55d7 ("scripts/dtc: Update to upstream version
v1.7.2-35-g52f07dcca47c") it is now a fatal error to U-Boot if our
device tree is not 8-byte aligned. In commit 85f586035d75 ("ARM: OMAP2+:
Pad SPL binary to 8-byte alignment before DTB") Beleswar Padhi explains
that we must have ALIGN(x) statements inside of a section to ensure that
padding is included and not simply that the linker address counter is
incremented. To that end, this patch:
- Aligns the final section before _end by 8-bytes by adding '. =
  ALIGN(8);' or changing an existing ALIGN(4) statement.
- Ensure that we do have alignment by adding an ASSERT so that when not
  aligned we fail to link (and explain why).
