1The spl command is used to export a boot parameter image to RAM. Later
2it may implement more functions connected to the SPL.

4SUBCOMMAND EXPORT
5To execute the command everything has to be in place as if bootm should be
6used. (kernel image, initrd-image, fdt-image etc.)
7
8export has two subcommands:
9	atags: exports the ATAGS
10	fdt: exports the FDT
11
12Call is:
13spl export <fdt|atags> [kernel_addr] [initrd_addr] [fdt_addr if fdt]
