* Reset Ethernet MAC + PHY if final boot mode is not network boot
See: Kernel warning and network failure when attempting to use
the network after bootloader times out. #144
* Improve handling of multiple bootable USB devices and remove USB_MSD_BOOT_MAX_RETRIES
* Resolve: No DHCPACK with DHCP relay agent #58
* Toggle USB root hub port power for 200ms on the first USB MSD boot attempt
See: Bootloader can't boot via USB-HDD after system reboot #151
* Update bootloader handover to support uart_2ndstage - requires a newer
start.elf firmware which will be via rpi-update.
* Assert PCIe fundamental reset if the final bootmode was not USB-MSD
because the OS might not do this before starting XHCI.
* Resolve: Unable to boot from USB MSD - Seagate 5Tb HDD backup drive #139
* Increase USB MSD timeout from 10 to 20 seconds.
* Max retries now default to zero because the default BOOT_ORDER includes
restart (0xf). Therefore, each boot-mode is now tried once before moving
to the next mode. The retries mechanism is largely redudant now that
the loop/restart mode exists.
* If TFTP fails and network boot retries > 0 then wait 5 seconds before
retrying to avoid overloading a misconfigured TFTP server.
* Map undefined boot-modes in BOOT_ORDER to SD (0x1) instead of stopping.
* Add missing pieeprom-2020-05-28
* Resolve: USB boot fails if the GPT contains no basic data or EFI partitions #130
* Resolve: Fix default BOOT_ORDER in mass storage beta #129
* Resolve: Add support for booting from a "superfloppy" disk #120
* Resolve: USB MSD timeout message - incorrect units #131
* Resolve: Recognize efi partition (0xef) as a valid boot #126
* The HDMI diagnostics screen now displays the most significant bytes of the SHA-256 of the config.txt file.
Now that 2020-04-16 has been released and appears to be stable move
the older binaries to and old (deprecated) directory. There's no
need to include old beta binaries in OS packages.
* Fix uart_2ndstage in the recovery.bin
* Fix missing watchdog reset if only the VL805 image is updated.
* Fix detection of VL805 EEPROM in recovery mode.
* If no EEPROM images are present then recovery.bin now renames
itself and reboots instead of treating this as an error.
Tweak analog settings for possible improvements to PCIe reliability
but unlikely to make a difference for most users and requires
corresponding changes in start.elf (future rpi-update)
The beta release with supports network boot is now stable enough
for most configurations. This is now frozen except for major bugs
in order to allow more experimental features to be released as
beta.
Added extra clarification for the beta `.bin` file, removing the static date from the command, as plenty of people would definitely copy/paste that blindly without realizing there are multiple versions in that directory. (Me being one of those people)
* Option to restrict automatic updates to bootloader and/or vl805
* Change the machine mode output variables
* recovery.bin: Rebuild from Gitlab
* Rename CURRENT_TS and LATEST_TS in machine output
* New beta recovery.bin which can update the VLI EEPROM before
start.elf is loaded. This is the recommended and default method
because no USB devices will be in use at this stage.
* Extend the USE_FLASHROM configuration to use the vl805 tool
to program the VL805 directly.
* Generate SHA256 checksums in .sig files for the bootloader and
and VL805 images. This is required by the new recovery.bin to
guard against corrupted files being flashed to the EEPROM(s).
* Various variable renames to distinguish between the bootloader
and the VL805 images.
