2017-12-07soc/intel/apollolake: Clean up UART codeAamir Bohra
Clean up and move UART related code under a single uart.c file. Change-Id: I9a30258ba43ee5920f585c1bd06bc25773778ec4 Signed-off-by: Aamir Bohra <aamir.bohra@intel.com> Reviewed-on: https://review.coreboot.org/22754 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-by: Furquan Shaikh <furquan@google.com> Reviewed-by: Subrata Banik <subrata.banik@intel.com>
2017-08-10soc/intel/common/uart: Refactor uart_common_initFurquan Shaikh
1. Create a new function uart_lpss_init which takes the UART LPSS controller out of reset and initializes and enables clock. 2. Instead of passing in m/n clock divider values as parameters to uart_common_init, introduce Kconfig variables so that uart_lpss_init can use the values directly without having to query the SoC. BUG=b:64030366 TEST=Verified that UART still works on APL and KBL boards.

2016-05-09drivers/uart: Use uart_platform_refclk for all UART modelsLee Leahy
Allow the platform to override the input clock for the UART by implementing the routine uart_platform_refclk and setting the Kconfig value UART_OVERRIDE_REFCLK. Provide a default uart_platform_refclk routine which is disabled when UART_OVERRIDE_REFCLK is selected. This works around ROMCC not supporting weak routines. Testing on Galileo: * Edit the src/mainboard/intel/galileo/Makefile.inc file: * Add "select ADD_FSP_PDAT_FILE" * Add "select ADD_FSP_RAW_BIN" * Add "select ADD_RMU_FILE" * Place the FSP.bin file in the location specified by CONFIG_FSP_FILE * Place the pdat.bin files in the location specified by CONFIG_FSP_PDAT_FILE * Place the rmu.bin file in the location specified by CONFIG_RMU_FILE * Build EDK2 CorebootPayloadPkg/CorebootPayloadPkgIa32.dsc to generate UEFIPAYLOAD.fd * Testing is successful when CorebootPayloadPkg is able to properly initialize the serial port without using built-in values.

2016-02-26soc/intel/apollolake: provide function to set up uart pads and controllerAaron Durbin
Instead of pushing the same code into each mainboard for configuring the the UART pads and initializing the host contoller provide a function to perform all the actions on behalf of the mainboard. The set of pads configured is dictated by the CONFIG_UART_FOR_CONSOLE Kconfig option.
