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>

2019-02-13cpu/intel/common: Split get_ia32_fsb()Kyösti Mälkki
It is desireable to not have printk() inside a function body that can be used for udelay(). This avoids potential infinite recursion.

2019-01-27src/cpu/intel: Set get_ia32_fsb function commonElyes HAOUAS
Add get_ia32_fsb returns FSB values in MHz of intel's CPUs. Also add get_ia32_fsb_x3 function. It returns round up 3 * get_ia32_fsb.
