[U-Boot-Users] does someone use the bootm to bootm kernel and ramdisk for mips arch?

As far as U-Boot is concerned please check "lib_mips/mips_linux.c" to
see how it uses linux_env_set() to pass  parameters  like  "memsize",
"initrd_start", "initrd_size" etc.

You will have to check within your kernel source tree how  they  pick
up  this  information  (and eventually ask MV support instead of this
list ;-)
