cpu/amd: Correct number of MCA banks cleared
Use the value discovered in the MCG_CAP[Count] for the number of MCA status registers to clear. The generations should have the following number of banks: * Family 10h: 6 banks * Family 12h: 6 * Family 14h: 6 * Family 15h: 7 * Family 16h: 6 Change-Id: I0fc6d127a200b10fd484e051d84353cc61b27a41 Signed-off-by: Marshall Dawson <marshalldawson3rd@gmail.com> Reviewed-on: https://review.coreboot.org/27923 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Martin Roth <martinroth@google.com>
