What makes a board properly built and how can a user determine whether their board is?

As of now this flag assumes that the bootloader is in LE mode. It is left to the kernel to switch to BE mode. This flag makes the kernel set necessary flags in SCTLR registers on entry.

What is a board port for arm64?

This is a generic patch for the architecture. Each driver needs to make necessary changes keeping the kernel endianness in mind. We have tested these patches on our X-Gene platform.
