If anyone has any objections, please let me know. ------------------ From: Phil Elwell [ Upstream commit 0de09025f161f67c07978c4742e221243d070d41 ] The ARM PL011 UART instances in BCM2711 are r1p5 spec, which means they have 32-entry FIFOs. The correct periphid value for this is 0x00341011. Thanks to N Buchwitz for pointing this out.
