From a6c525a7d5ad0dedc31dcc9719be6bc5fbc743dd Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ky=C3=B6sti=20M=C3=A4lkki?= Date: Wed, 16 Apr 2014 09:43:40 +0300 Subject: AMD AGESA cimx/sb700: Drop APIC_ID_OFFSET and MAX_PHYSICAL_CPUS MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Following boards use cimx/sb700: amd/dinar supermicro/h8qgi supermicro/h8scm tyan/s8226 Only amd/dinar had APIC_ID_OFFSET defined, thus all had 0x0. There was a nonsense preprocessor directive (MAX_CPUS * MAX_PHYSICAL_CPUS >= 1). Except for tyan, (MAX_CPUS * MAX_PHYSICAL_CPUS) % 256 == 0. Together with documented 4-bit restriction for APIC ID field, this APIC ID programming matches with MP tables and ACPI tables. I believe this would also fix cases of cimx/sb700 with MAX_CPUS<16, which we do not have in the tree.
