2019-11-03arch/x86: Use the stage argument to implement cbmem_topArthur Heymans
Currently all stages that need cbmem need an implementation of a cbmem_top function. On FSP and AGESA platforms this proves to be painful and a pointer to the top of lower memory if often passed via lower memory (e.g. EBDA) or via a PCI scratchpad register. The problem with writing to lower memory is that also need to be written on S3 as one cannot assume it to be still there. Writing things on S3 is always a fragile thing to do. A very generic solution is to pass cbmem_top via the program argument. It should be possible to implement this solution on every architecture. Instead trying to figure out which files can be removed from stages and which cbmem_top implementations need with preprocessor, rename all cbmem_top implementation to cbmem_top_romstage. TESTED on qemu-x86.

2019-11-03cpu/x86/tsc: Flip and rename TSC_CONSTANT_RATE to UNKNOWN_TSC_RATEKyösti Mälkki
The x86 timers are a bit of a mess. Cases where different stages use different counters and timestamps use different counters from udelays. The original intention was to only flip TSC_CONSTANT_RATE Kconfig to NOT_CONSTANT_TSC_RATE. The name would be incorrect though, those counters do run with a constant rate but we just lack tsc_freq_mhz() implementation for three platforms. Note that for boards with UNKNOWN_TSC_RATE=y, each stage will have a slow run of calibrate_tsc_with_pit(). This is easy enough to fix with followup implementation of tsc_freq_mhz() for the platforms. Implementations with LAPIC_MONOTONIC_TIMER typically will not have tsc_freq_mhz() implemented and default to UNKNOWN_TSC_RATE. However, as they don't use TSC for udelay() the slow calibrate_tsc_with_pit() is avoided. Because x86/tsc_delay.tsc was using two different guards and nb/via/vx900 claimed UDELAY_TSC, but pulled UDELAY_IO implementation, we also switch that romstage to use UDELAY_TSC.

This adds a common cbmem_top implementation to all coreboot target. In romstage a static variable will be used to cache the result of cbmem_top_romstage. In ramstage if CONFIG_RAMSTAGE_CBMEM_TOP_ARG is set a global variable needs to be populated by the stage entry with the value passed via the calling arguments. if CONFIG_RAMSTAGE_CBMEM_TOP_ARG is not set the same implementation as will be used as in romstage.

2019-10-28nb/intel/gm45: Add C_ENVIRONMENT_BOOTBLOCK supportArthur Heymans
The i82801ix_early_init is now called both in the bootblock and romstage. The rationale behind setting this up twice is to ensure bootblock-romstage compatibility in the future if for instance VBOOT is used. This moves the console init to the bootblock. The romstage now runs uncached. Adding a prog_run hooks to set up an MTRR to cache the romstage will be done in a followup patch. The default size of 64KiB is not modified for the bootblock as trying to fit both EHCI and SPI flash debugging needs a more space and 64KiB is the next power of 2 size that fits it. TESTED on Thinkpad X200.
