2016-07-21AMD k8 fam10: Fix CAR GLOBALS late in romstageKyösti Mälkki
Zero-filling memory below 1 MiB resets car_migrated variable so any CAR GLOBALs are not addressed correctly for the remaining time in romstage. Also there is no actual need to do this as ramstage loader handles BSS. This fixes regression with commit 70cd54310 that broke fam10 boards with romstage spinlocks enabled.

Without RELOCATABLE_RAMSTAGE have WB cache large enough to cover the greatest ramstage needs, as there is no benefit of trying to accurately match the actual need. Choose this to be bottom 16MiB. With RELOCATABLE_RAMSTAGE write-back cache of low ram is only useful for bottom 1MiB of RAM as a small part of this gets used during SMP initialisation before proper MTRR setup.

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.

2016-04-11cpu/x86/tsc: remove conditional compilationAaron Durbin
The delay_tsc.c compilation unit used the C preprocessor to conditionally compile different code paths. Instead of guarding large blocks of code allow the compiler to optimize out unreachable code.

2016-04-11cpu/x86/tsc: compile same code for all stagesAaron Durbin
The delay_tsc.c code took different paths depending __PRE_RAM__ being defined or not. Also, timer_monotonic_get() was only compiled in a !__PRE_RAM__ environment. Clean up the code paths by employing CAR_GLOBAL for the global state which allows the same code to be used in all stages. Lastly, handle apollolake fallout now that init_timer() is not needed in placeholders.c.

2016-04-11cpu/x86/tsc: prepare for CAR_GLOBAL in delay_tsc.cAaron Durbin
The current code in delay_tsc.c uses globals and is heavily guarded by a lot of preprocessor macros. In order to remove __PRE_RAM__ constraints one needs to use CAR_GLOBAL for the global variables. Therefore, abstract away direct access to the globals such that CAR_GLOBAL can be easily employed.

It's not selected by any path so it's a dead option with associated dead code. Remove the config option as well as the code paths that were never used any longer.
