here's a rough start at an outline for the bootm script based on the
code (I've only outlined the Linux/PPC boot case its seems the most
complicated). One of the first things we clearly need is a imload
command. Thoughts on the various disable_{interrupts, usb, caches} ?

bootm script:

disable_interrupts /* sets an env with the state of interrupts
before disabling */
#ifdef CONFIG_CMD_USB
disable_usb
#endif
#ifdef CONFIG_AMIGAONEG3SE
disable_caches
#endif
imload <kernel_image>

switch(on OS type from imload)

LINUX:
if (fdt)
fdt relocate to after kernel_image + padding
fdt fixups (board setup, etc)

if (ramdisk)
imload ramdisk
if (fdt)
fixup initrd info in fdt
bootm_linux
...
