docs: use #!/usr/bin/env bash shebang instead of #!/bin/bash ...

Some distributions might not have bash in /bin, but in $PATH.

Using #!/usr/bin/env bash solves this, and is consistent with how the
perl and python shebangs look like in the tree.

pstore: fix build by re-resolving botched merge conflict ...

297ac7288 ("pstore: Only capture log messages") removed the pstore console.
v3 of the eventually merged 75a74b5c ("console: fix out-of-bounds read
in dputc(/dev/*, ...)") reinstated part of this code, which broke the
pstore build because the now removed bufsize member had a user
reintroduced in the patch.

Fix this by reverting the offending patch's changes to the pstore code.
It wasn't applicable to begin with.

net: designware: eqos: fix NULL pointer use in dev_printf ...

Inside mdio_register, a read of the PHY's id register is attempted.
If it fails, we print an error message with eqos_err, which uses the
ethernet device's unique name, but at this time there has been none set,
because eth_register was not yet called. Fix this by using the MDIO bus
device instead.

net: designware: eqos: enable clocks before mdio_register ...

We can't be using the MAC including the MDIO controller while the clocks
are off, but this is exactly the case when mdio_register is called and
the interface is not yet up. To allow reading the PHY id to succeed
before the interface is up, turn on the clocks as part of the
initialization in the probe.

This fixes following error at probe time:

    ERROR: <NULL>: MDIO not idle at entry

The NULL is fixed in a follow-up commit.

filetype: mvebu: Fix kwbimage v1 detection ...

The kwbimage detection calculates a checksum over the first 31 bytes of
the image. This is correct for the v0 image format, but for the v1 image
format the checksum in the image also covers the extenstion headers.
These might not be completely present in the initial buffer provided to
file_detect_type(), so just drop the checksum calculation for v1 images.

designware_eqos.c contains an eqos_stop implementation to stop the NIC

am335x_sdram_size() may be called when we are not running at the
address we are linked at. This means tree switch conversions and

Since Kernel commit 5b63fb90adb9 ("ARM: dts: Fix incomplete dts data for
am3 and am4 mmc") (barebox commit 419db1f984 ("dts: update to
v5.3-rc7")) the AM33xx MMC2 controller is unconditionally enabled in the
dts. This has the effect that the driver probes for this device and then
can't access the registers as the clock is disabled. Enable the clock to
let the driver probe successfully.

ARM: dts: stm32mp: report psci v0.2 at least ...

ARM TF-A reports compatibility with PSCI v1.1 since v1.5. Upstream
ARM TF-A support for STM32MP was introduced with v1.6.
It's thus safe to assume that the STM32MP barebox will never have to
interact with a secure monitor implementing PSCI v0.1.

Overwrite the psci device tree compatible to specify v0.2. This is the
first version that implements PSCI_VERSION, which allows the barebox
psci client driver selected in this commit to query the actual PSCI
version and fix it up into the device tree.

This fixes an issue where resetting via PSCI fails in Linux because the
upstream device tree compatible:

  reboot: Restarting system
  Reboot failed -- System halted
