* 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.
* 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.
