* Add set_reboot_order API and config.txt properties
If set_reboot_order is defined in config.txt or set via vcmailbox
then this will override the bootloader config BOOT_ORDER property
on the next reboot. The parameter is stored in a reset safe register
and is cleared by the bootloader after reading it.
Typically, the config.txt value only be used via rpiboot to
override the boot-order on the next reboot. Otherwise, it should
reside in a conditional section so that the boot order is not
overridden on every reboot.
Example, test network boot
sudo vcmailbox 0x0003808b 4 4 0xf4612; sudo reboot
* Improved SDRAM refresh timings for Pi5 - 16GB
* Add an option to wait for the power button to be pressed before booting.
If POWER_OFF_ON_HALT=1 and WAIT_FOR_POWER_BTN=1 in the bootloader
config then the bootloader will wait for either the power button
to be pressed or an RTC alarm before booting. The wait state
switches the PMIC to STANDBY mode which is the lowest possible
power state.
* Stop the fan after after fan-probe
After the fan-probe has completed drive the fan PWM GPIO
to high if a fan was detected and let the OS take over.
* Add SD_QUIRKS for hardware bringup / workarounds
Add a new SD_QUIRKS flags property which can be used to
disable high-speed mode (bit 0). Other bits are reserved for
future use.
* Change uart_2ndstage default to 1 on Pi5
Change the default to 1 because this gives useful diagnostics
for device-tree loading with minimal overhead. Set uart_2ndstage=0
or BOOT_UART=0 to disable this.
* Move M.2 HAT+ detection to early boot.
Initialse M.2 HAT+ detection before DDR init to give NVMe
drive firmware more time to boot.
* Disable fan PWM before shutdown
Drive the RP1 fan PWM GPIO high before entering the VPU
sleep (POWER_OFF_ON_HALT=0) to stop the fan spinning.
* Disable fan PWM GPIO between RP1 init and fan probe
Drive fan PWM GPIO high during early boot to disable the fan
until it is probed during the device-tree setup stage.
This stops the spinning at max rpm during network-install.
* arm_dt: enable_uart defaults to 0 on 2712
The default value of enable_uart on 2712 is 0, regardless of the
presence of the debug UART cable, so guarantee that the default is
always set correctly.
Also, link to raspi-config as the mechanism for changing bootloader
update policies. raspi-config already provides a UI for selecting
the bootloader release streams and is the best place to provide
any other configuration options.
Flashrom is the default update mechanism on Pi5 and is not
cancellable. Remove this misleading message.
rpi-eeprom-update already has a message which knows about flashrom.
Retry flashrom updates on failure and explicitly verify the images.
So far, there haven't been any reports of flashrom failures but
retrying is the best course of action in case this failure ever
occurs.
* Enable banklow (and so NUMA) by default
banklow=1 (2712) and banklow=3 (2711) give the best performance.
* enable_uart=1 now enables a Linix UART console on the 40-pin header
unless a cable is detected on the dedicated boot-uart.
* Recreate internal bl31 stub from clean git tree to fix dirty commit
message.
* rp1fw: Add FIFO_STATE & DRAIN_TX, fix CAN_ADD_PROGRAM
RP1 firmware eb39cfd516f8c90628aa9d91f52370aade5d0a55 adds
methods to drain the TX FIFO and retrieve the state of both FIFOs. It
also fixes the CAN_ADD_PROGRAM implementation, which was fatally
broken.
* network-install - Update the UI to display the board model / variant.
* The 2024-11-12 automatically sets the POWER_OFF_ON_HALT property
according to the board-type so remove the override network install
images.
* Set NET_INSTALL_AT_POWER_ON=1 by default which briefly display
the network-install / boot-menu UI after a cold power-on.
This can be switched off by removing the line
either via "rpi-eeprom-config --edit" or the new menu in raspi-config
Advanced Options.
* net-install: Fix keyboard detection on hubs
* recovery: Always enable UART debug output on 2712
* Set POWER_OFF_ON_HALT defaults
The default value for POWER_OFF_ON_HALT on CM5 and Pi 500 will be 1.
Pi5 defaults to 0 for backwards compatibility.
* boot-time: Remove unnecessary 1 second delay when configuring DWC2 controller.
* Enable initial_turbo=60 by default
This reduces the time to get load and decompress the kernel.
* logging: Remove superfluous newline on SDRAM refresh changed messages
* Fix initial_turbo duration
The timeout counter for the previous implementation could run too quickly
causing the initial-turbo timeout to end earlier than expected.
* rp1-fw: Add the mailbox firmware interface, and PIO support that uses it.
* rp1-fw: Turn off unused 25MHz Ethernet refclk
Move everything older than the last automatic update (2024-09-23) to the
old firmware directory which is not included in the APT package. This
reduces the size of the APT updates.
