+ help
+ On certain platforms a boot speed gain can be realized if mirroring
+ the payload data stored in non-volatile storage. On x86 systems the
+ payload would typically live in a memory-mapped SPI part. Copying
+ the SPI contents to ram before performing the load can speed up
+ the boot process.
