soc/intel/common: Calculate and configure SF Mask 2
As per TGL EDS, two ways will be controlled with one bit of SF QoS register hence, this patch introduces SF_MASK_2WAYS_PER_BIT Kconfig to allow SoC users to select SF_MASK_2WAYS_PER_BIT to follow the EDS recommendation. Calculate SF masks 2: 1. if CONFIG_SF_MASK_2WAYS_PER_BIT: a. data_ways = data_ways / 2 Also, program SF Mask#2 using below logic: 2. Set SF_MASK_2 = (1 << data_ways) - 1 Change-Id: I442bed75f13d26f357cfb32c54c5fe9efa4b474b Signed-off-by: Subrata Banik <subrata.banik@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/56717 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org>
