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.

Also add some more automated checks to better model the platform's multiple windows into the same memory region and guard against accidental overlaps by a seemingly benign change to one window.

2015-09-22linking: link bootblock.elf with .data and .bss sections againAaron Durbin
Currently coreboot expects the loader to clear the bss section for all stages. i.e. stages don't clear their own bss. On ARM SoCs the BootROM would be responsible for this. To do that one needs to include the bss section data (all zeros) in the bootblock.bin file. This was previously being attempted by keeping the .bss info in the .data section because objcopy happened zero out non-file allocated data section data. Instead go back to linking bootblock with the bss section but mark the bss section as loadable allocatable data. That way it will be included in the binary properly when objcopy -O binary is emplyed. Also do the same for the data section in the case of no non-zero object values are in the data section. Without this change the trick of including .bss in .data was not working when there wasn't a non-zero value object in the data section. BUG=None BRANCH=None TEST=Built emulation/qemu-armv7 and noted bootblock.bin contains the cleared bss.

2015-06-12pistachio: add DDR3 initialization codeIonela Voinescu
Initialization for the Winbond W631GG6KB part using Synopsys DDR uMCTL and DDR Phy. This code adds a separate function for DDR3 initialization and moves all the necessary defines in a separate header file. The programming procedure that is executed at power up to bring up the uMCTL, PHY and memories into a state where reads and writes to the memory can be performed is the following: 1. uPCTL (Universal DDR protocol controller) initialization The timining registers TOGCNT1U, TINIT, TOGCNT100N and TRSTH needed for driving the memory power-up sequence are programmed as a function of the internal timers clock frequency. Organization (memory chip specific) values are set (column/bank/row address width and number of ranks), together with other static values (latency, timing, power up configuration). All these values are static, provided by the datasheet, being determined by the memory type, size and frequency. 2. PHY initialization The PHY is programmed with datasheet provided values, specifying the initialization values for it to send to the external memory (timing parameters). Also, delay lines (DLL) and strength of drive pads are calibrated (based on external conditions: temperature, voltage, noise) and locked. After that, the PHY goes through a trainig process (also dependent on the current conditions at boot time) to establish precise timing configuration between the DDR clock and DQS (data strobe) and between DQS and DQ (data). 3. Memory power up 4. Switch from configuration state to access state.

2015-04-22imgtec/pistachio: DDR reads return to controller with no bubblesIonela Voinescu
When the PHY is compiled to run in HDR(half data rate), then either NOBUB or FXDAT must be set to 1 in the DDR system general configuration register. NOBUB specifies that reads should be returned to the controller with no bubbles and this is felt preferable to the fixed latency option (FXDAT). Both of them inrease read latency.

2015-04-22imgtec/pistachio: DDR row/bank/column mappingIonela Voinescu
The DRAM configuration register, apart from holding the device density and width also has a rudimentary address mapping scheme. Currently this is set to the default Bank/Row/Column. This means that the memory is segmented into 8 chunks, each with a page detector. If all the activity is in one section of memory then the other 7 page detectors could be idle. Changing this to Row/Bank/Column would concatenate the page detectors meaning that all 8 could be used by a single initiator. This may not gain anything in a synthetic bandwidth test but could yield extra performance in a real world application or benchmark. BRANCH=none BUG=chrome-os-partner:37087 TEST=tested on Pistachio bring up board -> DDR initialized properly; all access to DDR works properly in Coreboot ramstage, Depthcharge and Linux; no performance tests were ran so far.

2015-04-22soc: select generic gpio lib on (almost) all non-x86 SOCsStefan Reinauer
BOARD_ID functionality is not what requires the GPIO lib, but it is the mainboard specific implementations that do. The option essentially says whether the SoC provides <soc/gpio.h> (with the interface required by the common GPIO code). Right now, x86 and Samsung's Exynos SOCs don't have support for this interface. So this should be selected by the SOC, not by BOARD_ID_SUPPORT.

2015-04-17pistachio: add DDR2 initialization codeIonela Voinescu
This is the intialization code specific to the Winbond W972GG6JB-25 part using Synopsys DDR uMCTL and DDR Phy. This is DDR2 initialization code only (currently present on the bring up board). DDR3 initialization code will follow for boards having DDR3 memory. The programming procedure that is executed at power up to bring up the uMCTL, PHY and memories into a state where reads and writes to the memory can be performed is the following: 1. uPCTL (Universal DDR protocol controller) initialization The timining registers TOGCNT1U, TINIT, TOGCNT100N and TRSTH needed for driving the memory power-up sequence are programmed as a function of the internal timers clock frequency. Organization (memory chip specific) values are set (column/bank/row address width and number of ranks), together with other static values (latency, timing, power up configuration). All these values are static, provided by the datasheet, being determined by the memory type, size and frequency. 2. PHY initialization The PHY is programmed with datasheet provided values, specifying the initialization values for it to send to the external memory (timing parameters). Also, delay lines (DLL) and strength of drive pads are calibrated (based on external conditions: temperature, voltage, noise) and locked. After that, the PHY goes through a trainig process (also dependent on the current conditions at boot time) to establish precise timing configuration between the DDR clock and DQS (data strobe) and between DQS and DQ (data). 3. Memory power up 4. Switch from configuration state to access state.
