XXX THIS IS VERY DIRTY HACK! XXX

this only works with latest rkflashtool from
 https://github.com/linux-rockchip/rkflashtool

e.g.)
 rkflashtool M 0x62000000 0x1000000 < ramdisk.img
 rkflashtool M 0x63000000 0x1000000 < kernel.img
 rkflashtool M 0x64000000 0x1000000 < parameter.img
 rkflashtool B 0x63000000 0x64000000

protocol may be incompatible with Rockchip. it may be changed in future.

you may omit rkcrc header from ramdisk and/or parameter.

if you omit rkcrc header from kernel, it will not be relocated to the
load address described in KERNEL_IMG: line in parameter. (i.e. kernel
needs to be coded to start at 0x63000000 in above case)
enable "reboot to maskrom"
support non-standard reset flag

e.g.
 $ rkflashtool b 0xf6 # reboot to fastboot mode
support NAND
Hacky changes to boot from ELF in NAND.
