* Update the FAT detection to support FAT16 for EFI/ESD paritions with
GPT instead of assuming FAT32. The latest firmware is also required
for a similar update.
* Increase the timeouts for MSD SCSI commands to reduce the risk of
timeouts when probing the capacity of slow to start devices
e.g. USB RAID with spinning disks.
This release makes major changes to the bootloader file-system code in
order to support new features and should be treated as a bleeding edge BETA
release!
* Improve file-system performance to reduce boot time.
* Preliminary support for IPV6 TFTP. Requires an updated start4.elf.
Details to follow.
* Fix VL805=1 option for CM4 IO boards that follow the same XHCI
design as Pi4B. Start.elf will be updated in the next rpi-update
release and the latest CM4 DTBs are required for the 'XHCI reset controller'
* Preliminary suppport for loading signed boot image files.
Requires updated GPU firmware.
* Avoid default PCIe / XHCI probe on CM4 unless required for the
current boot mode (USB_MSD or NVME).
* Leave PCIe RC in reset state when loading start.elf except for
USB-MSD mode.
* Minor update to BRCM SDRAM settings.
* Add USB_MSD_STARTUP_DELAY option (default 0 option).
This adds a configurable delay (in milliseconds) the first time
the USB host controller is initialised before device enumeration.
Normally, this should not be required. However, some HDD enclosures may
require an extended startup delay in order to spinup drives. Without this
the get-capacity command may stall and timeout.
* Use the latest BRCM SDRAM settings.
* FAT12 support for small bootloader ramdisk images.
* Minor file-system performance optimisations.
* Added recovery.bin config.txt option (erase_eeprom=1) to perform
an SPI chip-erase operation instead of programming the bootloader image.
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.
Move to to the old directory now that it's no longer referenced by rpi-eeprom-update.
Add a dependency check for 'lspci' which is normally provided by
pciutils or busybox and remove the failover to the vl805 helper.
Tweak the failure messages for missing dependencies to be slightly less
OS specific.
Move these out of the directories selected by APT now that 2020-09-03
is the default release.
Preserve the releases which were promoted to stable in-case these are
referenced via scripts.
