* arm_dt: Report OTP SDRAM size via device-tree Report the SDRAM in gigabits via device-tree as /proc/device-tree/chosen/rpi-sdram-size-gbit. Scripts reporting the device-capabilities should use this value (if defined) instead of the memory-size field in the boardrev row. * Apply UART_BAUD in early bootsys UART init Update bootsys and fatal error handlers to use the user defined UART_BAUD rate. * rpifwcrypto: Add support for ECDSA P-256 key generation Also, slightly improve the entropy by passing the system timer value as the personality string.
