fix(errata): workaround for Cortex-A510 erratum 2371937 Cortex-A510 erratum 2371937 is a Cat B erratum that applies to revisions r0p0, r0p1, r0p2, r0p3, r1p0, and r1p1. It is fixed in r1p2. The workaround is to set the ATOM field of CPUECTLR_EL1 (bits [40:38]) to 0b010, which will force all cacheable atomic operations to be executed near.
