* device/resource: Add _kb postfix for resource allocatorsKyösti Mälkki2022-06-221-1/+1
| | | | | | | | | | | | There is a lot of going back-and-forth with the KiB arguments, start the work to migrate away from this.

* soc/amd/cezanne,picasso/uart: implement read_resourceFelix Held2021-10-151-1/+6
| | | | | | | | | | | | | Implement the read_resources function for the UART devices so that the resource allocator knows about their fixed MMIO resources when enabled. TEST=UART still works on Mandolin.

* soc/amd/common/blocks/include: rename gpio_banks.h to gpio.hFelix Held2021-09-231-1/+1
| | | | | | | | | | | This brings the AMD SoC GPIO code in line with the Intel SoC code and removes the not really needed suffix.

* soc/amd: rename program_gpios to gpio_configure_padsFelix Held2021-09-231-1/+1
| | | | | | | | | | | | | | | | | Use the same function name as in soc/intel for this functionality. This also brings the function name more in line with the extended version of this function gpio_configure_pads_with_override which additionally supports passing a GPIO override configuration. This might cause some pain for out-of-tree boards, but at some point this should be made more consistent, so I don't see a too strong reason not to do this.

* soc/amd/cezanne: factor out AOAC offset definesFelix Held2021-06-161-0/+1
| | | | | | | | | | | | Factoring out those defines allows using them easily in the ACPI code without having to use preprocessor macros.

* soc/amd/cezanne: add remaining non-ACPI parts of UART supportFelix Held2021-01-141-0/+35
| | | | | | | | | | | | | | | | The ACPI part still needs some more code to be in place, so add that later. TEST=Together with the currently not merged rest of the amdfw patch train applied this results in working serial console in bootblock in Majolica.
