On Raspberry Pi 5 there are dedicated pins for the bootloader SPI
EEPROM. This makes it possible to do immediate updates via flashrom.
The "current" EEPROM config is the EEPROM config at boot rather
than what has just been written to the SPI flash because this is
consistent with current behaviour.
To use flashrom instead of recovery.bin for bootloader updates
set RPI_EEPROM_USE_FLASHROM=1 in /etc/defaults/rpi-eeprom-update
BCM2711
On CM4, Pi4, CM4-S, Pi400 config.txt must be modified to disable
the analog audio driver which shares the GPIO pins used by the
bootloader EEPROM.
dtparam=spi=on
dtoverlay=audremap
dtoverlay=spi-gpio40-45
* Fix SDIO / WiFi clock-setup for BOOT_ORDER=0xf14
* Fix SD power-on-reset
* Firmware support for improved watchdog driver
* Update DHCP Option97 to be R,P,i,5 on Pi5
The Pi5 EEPROM is larger and can take longer to update which
slightly increases the change of failure if the board power is
disconnected across an update. Re-enable recovery.bin for SD
updates for now.
* Add support for HAT gpiomap for improved HAT compatibility.
* Add I2C probe for DSI display auto detect
* Automatically set dtparam=nvme if booted from nvme
* Fix network boot reset issue where only the first attempt works.
* Adding pciex4_reset=0 to config.txt will leave RP1 PCIe enabled when
ARM stage is started.
* Prevent HDMI diagnostics being displayed immediately when waking
after HALT.
* Update board-name - "Rasberry Pi 5"
The EEPROM release names were changed to follow the naming
in raspi-config some time ago. Since the firmware directory
is being renamed to be chip specific for Pi5 support it's
good time to swap the symlink / release names.
BCM2711 and BCM2712 require different EEPROM firmware and
consequently the binaries have been moved to chip specific
firmware directories.
firmware-2711 / firmware-2712
Update the test/install script to remove previous firmware files.
This fixes a problem where the install script failed because
beta is now a symlink and not a directory.
Remove the beta release folder and replace with a symlink to the
'latest' release.
Including beta firmware in the APT release causes unecessary churn
and occasionally causes an issue where a user might end up on an
old and unsupported beta release.
Instead, beta releases are will be feature specific and installed
manually via 'rpi-eeprom-config --edit beta-firmware.bin'
i.e. beta releases will be out-of-package custom firmware releases
downloaded from github. The functionality will be merged into
a new latest/stable release or abandoned.
N.B. The old beta releases have been archived to 'old' but are no
longer included in APT.
Debian's raspi-firmware package assumes the boot partition is mounted as
/boot/firmware/ rather than /boot/. This commit adds support for either
approach by default.
latest and default are links to directories, so follow them.

The busybox implementation of find does not detect recursive nested
symlinks, this results in it finding multiple instances of of_node
matching -samefile, the result of which then fails the -e path test.
The of_node symlink we're tyring to find should match the path
/sys/bus/nvmem/devices/*/of_node so just limit the find depth to 3 as
there's no point searching deeper than that.
