2021-01-26cpu/intel/common/fsb.c: Add Broadwell CPUID modelsAngel Pons
Like Haswell, Broadwell has a "FSB" speed of 100 MHz. Add the IDs for both the traditional and ULT variants of Broadwell, because the CPU driver for Haswell already contains CPUIDs for both Broadwell types. Without this patch, Broadwell CPUs would hang when trying to print the first console log message, but only if flashconsole was not enabled. This was missed in commit f542b7bcef (cpu/intel/haswell: Add Broadwell CPUIDs and microcode) and went unnoticed until now because the tests were done with flashconsole enabled, which somehow boots properly even though the console time tracking would not work (depends on TSC). Tested on out-of-tree Acer E5-573, fixes booting without flashconsole.

2020-03-15treewide: Replace uses of "Nehalem"Angel Pons
The code in coreboot is actually for the Arrandale processors, which are a MCM (Multi-Chip Module) with two different dies: - Hillel: 32nm Westmere dual-core CPU - Ironlake: 45nm northbridge with integrated graphics This has nothing to do with the older, single-die Nehalem processors. Therefore, replace the references to Nehalem with the correct names.

2019-12-02src/: Remove g_ prefixes and _g suffixes from variablesPatrick Georgi
These were often used to distinguish CAR_GLOBAL variables that weren't directly usable. Since we're getting rid of this special case, also get rid of the marker. This change was created using coccinelle and the following script: @match@ type T; identifier old =~ "^(g_.*|.*_g)$"; @@ old @script:python global_marker@ old << match.old; new; @@ new = old if old[0:2] == "g_": new = new[2:] if new[-2:] == "_g": new = new[:-2] coccinelle.new = new @@ identifier match.old, global_marker.new; @@ - old + new @@ type T; identifier match.old, global_marker.new; @@ - T old; + T new; @@ type T; identifier match.old, global_marker.new; @@ - T old + T new = ...; There were some manual fixups: Some code still uses the global/local variable naming scheme, so keep g_* there, and some variable names weren't completely rewritten.

2019-07-01intel/fsp_rangeley: Use fixed FSB/BCLK value 100 MHzKyösti Mälkki
Prior to commit d731a24 src/cpu/intel: Set get_ia32_fsb function common value of 200 was silently used as a default for fsp_rangeley (model_406dx) in cpu/x86/lapic/apic_timer:set_timer_fsb(). After the commit, get_ia32_fsb() returns -2, eventually resulting with divide-by-zero in timer_monotonic_get(), as get_timer_fsb() returns 0. Add Rangeley CPUID model 0x4d to get_ia32_fsb() as a fix, using BCLK = 100 MHz based on the comments in northbridge/intel/fsp_rangeley/udelay.c Change-Id: I306f85dba9b1e91539fc0ecc9b2ae9d54f82be6c Signed-off-by: Kyösti Mälkki <kyosti.malkki@gmail.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/33822 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: HAOUAS Elyes <ehaouas@noos.fr>
