 * __boot_cpu_mode records what mode CPUs were booted in.

 * A correctly-implemented bootloader must start all CPUs in the same mode:

 * In this case, both 32bit halves of __boot_cpu_mode will contain the

 * same value (either 0 if booted in EL1, BOOT_CPU_MODE_EL2 if booted in EL2).

 * same value (either BOOT_CPU_MODE_EL1 if booted in EL1, BOOT_CPU_MODE_EL2 if

 * booted in EL2).

 *

 * Should the bootloader fail to do this, the two values will be different.

 * This allows the kernel to flag an error when the secondaries have come up.
