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.
BCM2711 and BCM2712 require different EEPROM firmware and
consequently the binaries have been moved to chip specific
firmware directories.
firmware-2711 / firmware-2712
Interesting changes since the last default release:-
* Display VC_BUILD_ID strings instead of the SHA256 hash
* Add support for [cm4] and [pi400] config conditionals filters.
* Change network boot to use the same "RXID" Ethernet PHY configuration as the 5.10 kernel
* TFTP - reply to duplicate ACKS
* Skip rendering of HDMI diagnostics display for the first 8 seconds unless an error occurs.
* UDP checksum fixes
