Update make-imager-release to remove the release-CHIP directories
which contain the plain .zip files. These are used as the input
to make-recovery-images which are disk images.
RPi Imager expects to download disk-images rather than .zips so
remove the temporary directories to avoid confusion.
See: https://github.com/raspberrypi/rpi-eeprom/issues/770
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
* Add support for the BCM2711 XHCI controller - BOOT_ORDER 0x5
* XHCI protocol layer fixes for non-VLI controllers
* Avoid USB MSD timeout of there is only one device
* Implement tryboot for OS upgrade fallback
* Check the update-timestamp before applying an update in SELF-UPDATE mode
* Update recovery.bin to 2021-04-13 release for error pattern fix
on SDRAM failure.
