* 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. * cm5: Add support for 8-bit bus width eMMC * Query all sdram devices for temperature when adjusting refresh * Add support for more SDRAM die configurations.
