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.
* Fix PCIe BAR setup issue which prevented NVMe boot from working with some PCIe switches
See: https://github.com/raspberrypi/firmware/issues/1833
* Boot-menu improvements
Remain in the forced boot mode until the menu is used to select a different
boot-mode or reset to the original boot-order.
SD card high-speed/low-voltage mode can only be exited by powercycling.
Pi 4s before rev 1.4 lack the power switch required to do this, so
must resort to a global reset that turns off many things, including
SDRAM.
To ensure correct operation, the bootloader checks that the SD I/O
voltage is the expected 3.3V, forcing a power cycle if it isn't.
However, this doesn't take advantage of presence of the dedicated
SD power switch, always forcing a global reset, a consequence of which
can be the loss of SDRAM content - including any ramoops dump of the
crash logs.
Make the bootloader more SD_PWR_ON aware, only triggering a global
reset if one isn't found.
See: https://github.com/raspberrypi/linux/issues/5298
* Introduce a new boot-menu feature where pressing SPACE at power on
gives the user a one-shot option to select a different boot mode.
e.g. Select USB boot if the default SD card is corrupted or unavailable.
* Display the bootloader network-install UI for longer on a cold boot to make
this feature more visible to first time users.
To revert to the previous behaviour remove NET_INSTALL_AT_POWER_ON=1
from the bootloader config.
* Support non-UUID HAT mapping
Extend the HAT map support to allow matching on product and vendor
strings, as well as product ID and version. As a minimum, there must
be a product string - if that matches, the other keys are considered.
Without a product key, the UUID is compared as before.
* Remove requirement for GPT ptable array to be at LBA-2
See: https://github.com/raspberrypi/rpi-eeprom/issues/585
* 2712C1 clock manager improvements to slightly reduce idle power ~50mW saving
* Adjust SDRAM page-hold and auto-precharge to improve performance.
~2% improvement with Geekbench 6
* armstubs: 2712: Rebuild with updated max-power throttle and direct stream settings
See: fc45bc492d
* debug: Only display the program_pubkey log if configuring secure-boot
20 seconds is a little too short for safety with flashrom if every
page has to be erased and re-written. Bump this to 60 seconds
which is probably too long but nothing good will come from
interrupting flashrom.
* arm_dt: Consult the hat_map for all HATs
* USB boot - ignore RP2 / RP3 MSD device in BOOTSEL mode.
* recovery.bin - Fix erase_eeprom to not block reboot_recovery
* Fix self-update to continue to boot instead of retrying forever
if the EEPROM is write protected.
https://github.com/raspberrypi/rpi-eeprom/issues/597
- 2024-07-30 is marked `default` here, but the image is actually in `latest`
- 2024-07-25 doesn't specify default or latest - fix that
(Aside: neither seem to have found their way to apt yet).
* Optimize all-banks/per-bank refresh timings for Pi5 8GB
* Improve compatibility for booting from some USB SD card readers
https://github.com/raspberrypi/rpi-eeprom/issues/527
* Add enable_rp1_uart=1 to config.txt to initialise RP1 UART0 immediately
prior to starting the ARMs get earlycon on 40-pin header (pins 14,15)
Also requires pciex4_reset=0 in config.txt
earlycon=pl011,0x1f00030000,115200n8
* Enable the usage of program_rpiboot_gpio in config.txt for recovery.bin
without requiring secure-boot to be enabled.
This may be useful CI systems provisioning images on Pi4B / Pi400 via RPIBOOT.
This is an OTP setting and cannot be reverted after programming.
See https://www.raspberrypi.com/documentation/computers/config_txt.html#program_rpiboot_gpio
* The [pi5] conditional statement should apply to the entire pi5
family i.e. include cm5 as well.
* Bump SDIO bus priorities to that a GPU/RAM intensive processes
can't unnecessarily stall an I/O processes.
* Assorted log message tidyups.
* Add timestamps to UART log messages.
* Add support for [tryboot] conditional the bootloader EEPROM
config file.
See: https://github.com/raspberrypi/rpi-eeprom/issues/454
* Fix MAX_RESTARTS parameter
See: https://github.com/raspberrypi/rpi-eeprom/issues/576
* Add recovery_reboot option to config.txt for rpiboot which causes
the system to reboot after updating the bootloader.
* Improve secure-boot OTP provisioning logging.
* Fix setting to enable secure-boot mode on Pi4B
Interesting changes since the last automatic update:
* Enable network install
* Enable over-clocking frequencies > 3GHz
See: ttps://github.com/raspberrypi/firmware/issues/1876
* Adjust SDRAM refresh rate according to temperature and address a performance
gap between 4GB and 8GB parts in benchmarks.
See: https://github.com/raspberrypi/firmware/issues/1854
* Support custom CA certs with HTTPS boot
* Move non Kernel ARM stages back to 512KB
https://github.com/raspberrypi/firmware/issues/1868
* Assorted HAT+ and NVMe interop improvements.
* Fix TRYBOOT if secure-boot is enabled.
* Preliminary support for D0 and CM5.
* Switch to building the Pi4 firmware from the common Pi4/Pi5
mainline release. This doesn't change the Pi4 features
but should make it quicker to release bug fixes in common code.
* Fix issue that caused the TRYBOOT flag to be lost in secure-boot mode.
* dtoverlay: Use %u when converting u32s to strings
See: https://github.com/raspberrypi/linux/issues/6039
* Improved debug messages for secure-boot.
* Generate the bootloader diagnostics qrcode at run time.
