I'm trying to use the UART0 but I can not start it.
The base address provided in the datasheet is 0x7E20100. I'm not using Linux, I'm working on a custom kernel ... my question is how to translate the address above to use without Linux? I've tried 0x2020100, 0x20201000, 0x7E20100, 0x7E201000 ... but nothing to make the PL011 work. My board is a RaspberryPi B+ version 1.2. Thanks for any help
