help
Execute-In-Place allows the kernel to run from non-volatile storage
directly addressable by the CPU, such as NOR flash. This saves RAM
With the ARCH_MULTIPLATFORM_STRICT option, it becomes much easier to enable the ERRATA options when we know at configuration time that we don't care about the generic case. The previous configuration makes XIP_KERNEL option fundamentally non-MULTIPLATFORM, but it's still valid to select it when building for !ARCH_MULTIPLATFORM_STRICT and selecting only the one machine that you want to run on. So allow ARM_ERRATA and XIP_KERNEL options to be enabled without ARCH_MULTIPLATFORM_STRICT.
