* serial: Drop .remove functions from all driversAndrey Smirnov2018-04-171-10/+0
| | | | | | | | | | | | | | | | | | | Depending on specifics, some 'serdev' devices might need prevent parent console device from being removed and corresponding memory deallocated to properly function until the very end of Barebox's execution. An example of such a use-case would be a reset handler relying on a serdev device for transport. To avoid having to develop complicatione reference counting/ownership scheme drop all of the code that calls console_unregister() and frees the memory effectively making the problem above impossible to arise. All of the de-initialization that serial drivers were doing in their .remove functions was somewhat superflous anyway, so this change should be pretty harmless.

* driver: replace dev_request_mem_region with dev_request_mem_resourceSascha Hauer2016-03-071-1/+5

* console: drop f_caps and check the function pointer getc/putc insteadJean-Christophe PLAGNIOL-VILLARD2013-09-211-1/+0
| | | | | | | | | | None of the driver make the difference between STDOUT and STDERR.

* Support most Samsung SoCs in S3C serial driverAlexey Galakhov2012-05-141-17/+38
| | | | | | | | | | | | | | | | Ok, I assume this should go into separate series. It fits both S5PV210 and S3C6410. This adds support for S3C and S5P architectures (all of my knowledge) to the serial driver. Since the only difference between them is in clock handling, this is moved to an arch-dependent separate function. Most modern architectures should define S3C_UART_HAS_UBRDIVSLOT and S3C_UART_HAS_UINTM.
