Interesting changes since the last release:-
2026-01-09: arm_loader: Apply rpifwcrypto lock permissions GET/SET USER OTP (latest)
- arm_loader: Apply rpifwcrypto lock permissions GET/SET USER OTP
Previously, the GET/SET user OTP mailboxes would provide access to the
device unique private key. Update the mailbox API to fail if the
key has been locked via lock_device_private_key=1 in config.txt or
the associated mailbox call.
GET/SET user OTP fails by setting the result tag to the standard
error code (0x80000000). The dedicate GET/SET private key continue
to fail the entire mailbox operation to force vcmailbox to exit
with a non-zero error code. - Query all sdram devices for temperature when adjusting refresh
- Add support for more SDRAM die configurations.
