ARM: 9444/1: add KEEP() keyword to ARM_VECTORS

2025-04-10T12:44:45+00:00

commit c3d944a367c0d9e4e125c7006e52f352e75776dc upstream.

Without this, the vectors are removed if LD_DEAD_CODE_DATA_ELIMINATION
is enabled.  At startup, the CPU (silently) hangs in the undefined
instruction exception as soon as the first timer interrupt arrives.

On my setup, the system also boots fine without the 2nd and 3rd KEEP()
statements, so I cannot tell whether these are actually required.

ARM: 9443/1: Require linker to support KEEP within OVERLAY for DCE

2025-04-10T12:44:45+00:00

commit e7607f7d6d81af71dcc5171278aadccc94d277cd upstream.

ld.lld prior to 21.0.0 does not support using the KEEP keyword within an
overlay description, which may be needed to avoid discarding necessary
sections within an overlay with '--gc-sections', which can be enabled
for the kernel via CONFIG_LD_DEAD_CODE_DATA_ELIMINATION.

Disallow CONFIG_LD_DEAD_CODE_DATA_ELIMINATION without support for KEEP
within OVERLAY and introduce a macro, OVERLAY_KEEP, that can be used to
conditionally add KEEP when it is properly supported to avoid breaking
old versions of ld.lld.

ARM: dts: imx6ul-tqma6ul1: Change include order to disable fec2 node

2025-04-10T12:44:07+00:00

[ Upstream commit 22d8f69c8ddcd036d6e81589e95a058b86272bd1 ]

TQMa6UL1 has only one FEC which needs to be disabled as one of the last
steps.
imx6ul-tqma6ul2.dtsi can't be included in imx6ul-tqma6ul1.dtsi as the
defaults from imx6ul.dtsi will be applied again.

ARM: dts: omap4-panda-a4: Add missing model and compatible properties

2025-04-10T12:44:01+00:00

[ Upstream commit ea07a4775df03852c353514b5b7646a17bd425be ]

When moving the model and compatible properties out of the common
Pandaboard files and in to the specific boards, the omap4-panda-a4
file wasn't updated as well and so has lacked a model and compatible
entry ever since.

Pull SoC fixes from Arnd Bergmann:
 "The majority of these last fixes are for devicetree files.

  These address two important regressions for the Qualcomm SMMU and the
  Raspberry Pi 4 USB controller, as well as a larger number of patches
  fixing minor mistakes in board specific files for Rockchips, i.MX,
  starfive and broadcom.

  The non-DT changes are

   - A fix for an old boot regression on Renesas shmobile chips

   - Another boot time regression for for the Qualcomm PDR SoC driver,
     among a few other Qualcomm firmware driver fixes for efivars and
     tzmem

   - Minor Kconfig fixes for davinci and OMAP1

   - Minor code fixes for sparx5 reset controllers, OMAP memory
     controller, i.MX SCU, cpufreq and SoC drivers and a Hisilicon SoC
     driver

   - One more update to the Asahi maintainers, adding Neal Gompa as a
     reviewer"

ARM: shmobile: smp: Enforce shmobile_smp_* alignment

When the addresses of the shmobile_smp_mpidr, shmobile_smp_fn, and
shmobile_smp_arg variables are not multiples of 4 bytes, secondary CPU
bring-up fails:

    smp: Bringing up secondary CPUs ...
    CPU1: failed to come online
    CPU2: failed to come online
    CPU3: failed to come online
    smp: Brought up 1 node, 1 CPU

Fix this by adding the missing alignment directive.

After using the device for a while, Tom reports that he initially described
the switch port labels incorrectly. Apparently, ASUS's own firmware also
describes them incorrectly. Correct them to what is seen on the chassis.
