- // address of the UART is hardcoded, and only the baud rate may be wrong,
- // but if we don't know the base address yet, we may be poking into memory
- // that does not tolerate being poked into;
- // - SEC and PEI phases produce debug output only, so with debug disabled, no
- // initialization (or device tree parsing) is performed at all.
- //
- // Note that this means that on *every* Write () call, the device tree will be
- // parsed and the UART re-initialized. However, this is a small price to pay
