(cherry picked from commit 9c2e0ba8d8)
Stop overriding CCACHE_COMPILERCHECK from rules.mk and rely on
ccache's default, which hashes the compiler binary's mtime and
size.
For a local tree that is enough: the toolchain only changes when
it is rebuilt, and a rebuild updates mtime and size. Users who
want a stricter check can still set CCACHE_COMPILERCHECK in their
environment.
CI does not depend on this export either. The workflow writes a
secondary ccache.conf with
compiler_check=string:<toolchain-commit-sha>
so the cache key is tied to the toolchain source revision. That
is both stricter than the previous "%compiler% -v -c" setting
and portable across runners, where compiler mtimes would not
match after restoring a cache archive.

(cherry picked from commit 3956287514)
The sama5d4_xplained_nandflash target incorrectly references microchip_sama5d3-xplained as its BUILD_DEVICES value.
This appears to be a copy-paste error, as all other SAMA5D4 Xplained targets (e.g. mmc and spiflash) correctly use microchip_sama5d4-xplained. The target name itself also clearly refers to the SAMA5D4 platform.
In addition, the SAMA5D3 Xplained and SAMA5D4 Xplained boards use different NAND flash hardware and configurations, so pointing the nandflash target to a SAMA5D3 device is incorrect and may lead to invalid builds or runtime issues.
Fix the inconsistency by updating BUILD_DEVICES to microchip_sama5d4-xplained, aligning the nandflash target with the rest of the SAMA5D4 definitions and ensuring the correct device mapping.

This patch backports a small but important part of the upstream commit:
b3f1b9e2aa07 build: Remove INCLUDE_MEMORY [PR117737]
Its original commit message fails to mention that the commit also moves
the `#include <memory>` to an earlier position within system.h,
which is the actual change that we're after in this patch.
Building our GCC 14.3 with host GCC 16, the inclusion order starts to matter,
which is an issue that was also touched upon by the upstream commits:

The Xiaomi AX6000 has three radios:
- IPQ5018 integrated 2.4 GHz (ath11k AHB, wifi0)
- QCN9024 on PCIe0 (ath11k PCI, QCA8074-class 5 GHz)
- QCA9887 on PCIe1 (ath10k, 5 GHz)
The DTS previously kept pcie1 disabled because the controller
could not bring the link up. The real cause was the PERST GPIO
polarity: the stock device-tree uses GPIO_ACTIVE_HIGH on GPIO18
for the QCA9887 card, while OpenWrt had GPIO_ACTIVE_LOW, leaving
the card held in reset.
With the correct polarity the PCIe1 link trains and the QCA9887
enumerates at 01:00.0. ath10k loads firmware-2.bin, registers
phy0 with mac80211, and provides a functional 5 GHz AP.
Tested on a reworked Xiaomi AX6000 with QCA9887 soldered in.
All three radios enumerate, load firmware and beacon
successfully; scan, association and data traffic confirmed on
each radio.

The DFI ASL553 is a 3.5" SBC very similar to the ADN553. The network
topology is identical, so both boards share the same network
configuration.
Differences from the ADN553:
* CPU: Intel Atom x7835RE (8C, 12W) / x7433RE (4C, 9W) /
x7213RE (2C, 9W) / x7211RE (2C, 6W)
(Amston Lake / x7000RE series instead of Alder Lake-N)
* Ethernet: Intel I226IT instead of I226V
* Audio: Realtek ALC888S instead of ALC888

The DFI ADN553 is a 3.5" SBC based on Intel Atom Alder Lake-N
processors with three Intel I226V 2.5GbE ports.
Specs:
* CPU: Intel Atom x7425E (4C, 12W) / x7213E (2C, 10W) /
x7211E (2C, 6W)
* RAM: 1x DDR5 SO-DIMM, up to 16GB
* Storage: 1x M.2 M key 2242/2280 (PCIe Gen3 x1/SATA3),
1x SATA 3.0
* Ethernet: 3x 2.5GbE RJ-45 (Intel I226V)
* USB: 4x USB 3.2 (rear), 2x USB 2.0 (internal)
* Expansion: 1x M.2 B key 3052 (USB3/USB2, opt. PCIe x1, SIM),
1x M.2 E key 2230 (USB/PCIe x1, CNVi)
* Display: 1x HDMI, 1x Type-C DP Alt. Mode, 1x LVDS/eDP
* Power: 9-36V DC wide range input
* TPM: dTPM 2.0 (NPCT750AADYX)
* Form factor: 3.5" SBC (146mm x 102mm)
Installation:
1. Write the combined-efi.img to a USB drive:
dd if=combined-efi.img of=/dev/sdX conv=fdatasync
2. Boot the ADN553 from the USB drive via the UEFI boot menu.
3. For permanent installation, write the image to the M.2 or
SATA storage device.
The board uses "Default string" as DMI sys_vendor and product_name
placeholders, so board detection is fixed by filtering these out and
falling through to board_vendor (DFI Inc.) and board_name (ADN553).
The three I226V NICs are pinned to their PCIe paths to ensure
consistent interface ordering matching the physical left-to-right
port layout. eth0 is assigned as WAN and eth1/eth2 as LAN.

Commit b4d7263bc3 ("kernel: of: avoid some unnecessary bad cell count

when attempting translating non-translatable addresses"), which started
requiring #address-cells for a device's parent if we want to use the
reg resource in a device node.
Many Chromium devices use a /firmware/coreboot device node that is
patched in by the boot firmware. These structures look something like:
# find /sys/firmware/devicetree/base/firmware/
/sys/firmware/devicetree/base/firmware/
/sys/firmware/devicetree/base/firmware/scm
/sys/firmware/devicetree/base/firmware/scm/compatible

/sys/firmware/devicetree/base/firmware/coreboot/reg
/sys/firmware/devicetree/base/firmware/coreboot/name

Notably, there is no #{address,size}-cells in /firmware.
This breaks any driver relying on a device under /firmware, such as the
coreboot_table driver.
This is technically an ill-formatted FDT, and so we might as well just
add the properties ourselves.

- Set up a TFTP server on IP 192.168.1.88 and connect to the WAN port (upper port)
- Provide the Cudy firmware as recovery.bin in the TFTP server
- Press the reset button while powering on the device
- Recovery process is started now

Some Banana Pi BPI-R4 BE14 WiFi modules are shipped with zeroed
tx_power fields in EEPROM (2G/5G/6G). This leads to low transmit power
on affected bands.
This overlay provides known-good EEPROM data (including correct tx_power
values for 2G/5G/6G bands) dumped from a working BE14 module.
To enable BE14 overlay, add into u-boot bootconf_extra
parameter: 'mt7988a-bananapi-bpi-r4-wifi-be14'.
You can use example script:
overlay="mt7988a-bananapi-bpi-r4-wifi-be14"
current="$(fw_printenv -n bootconf_extra 2>/dev/null)"
if [ -n "${current}" ]; then
fw_setenv bootconf_extra "${current}#${overlay}"
else
fw_setenv bootconf_extra "${overlay}"
fi
Earlier proposal proposed in [1] was fallback to default values if
invalid EEPROM content is detected.
