Kconfig doesn't have any knowledge of specific v7 cores, so it is possible to select errata workarounds that may cause inadvertent behaviour when executed on a core other than those targetted by the fix. This patch improves the variant and revision checking in proc-v7.S so that the primary part number is also considered when applying errata workarounds.
