2019-11-04cpu/qemu-x86: Add x86_64 bootblock supportPatrick Rudolph
Add support for x86_64 bootblock on qemu. Introduce a new approach to long mode support. The previous patch set generated page tables at runtime and placed them in heap. The new approach places the page tables in memory mapped ROM. Introduce a new tool called pgtblgen that creates x86 long mode compatible page tables and writes those to a file. The file is included into the CBFS and placed at a predefined offset. Add assembly code to load the page tables, based on a Kconfig symbol and enter long in bootblock. The code can be easily ported to real hardware bootblock. Tested on qemu q35.

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.

2019-11-02cpu/x86: Add a prog_run hook to set up caching of XIP stagesArthur Heymans
Some platforms lack a non-eviction mode and therefore caching the whole ROM to speed up XIP stages can be dangerous as it could result in eviction if too much of the ROM is being accessed. The solution is to only cache a region, about the size of the stage that the bootblock is about to load: verstage and/or romstage. TODO: now a limit of 256KiB is set for the total amount of cache that can be used. This should fit most use cases for the time being.

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.

Fix regression from commit ecea916 cpu/intel/common: Extend FSB detection to cover TSC MSR_EBC_FREQUENCY_ID (0x2c) was not defined for affected CPU models and rdmsr() caused reset loops. Implementations deviate from public documentation. Change to IA32_PERF_STATUS (0x198) already used in i945/udelay.c to detect FSB to TSC multiplier.

2019-09-19cpu,mb,soc: Init missing lb_serial struct fieldsJacob Garber
Initialize the input_hertz and uart_pci_addr fields of the lb_serial struct to prevent later undefined reads in lb_add_serial(). This was done for exynos5420 in commit ff94e00362 (soc/samsung/exynos5420/uart.c: Init new serial struct variables), and this patch finishes the rest. Note that not all of the drivers can have the UART PCI address configured at build time, so a follow-up patch will be needed to correct those ones.
