I managed to port the uboot api to LK which means we don't need uboot anymore :)
Code: 
couldn't get memory map, not enabling caches[1430] API_env_get: grub_term
[1430] API_dev_enum
Welcome to GRUB!

error: unknown terminfo type `r'.

GNU GRUB  version 2.02~beta2

  Minimal BASH-like line editing is supported. For the first word, TAB 
  lists possible command completions. Anywhere else TAB lists possible 
  device or file completions.

you're talking about datamedia? :)
I already thought about automatically patching systems to support this. the following changes are needed:
fstab(not a problem)
init.aries.rc(requires some crazy string parsing, but still possible)
storage_list.xml - that's a problem because this file is packed into android frameworks. maybe xposed could work around this problem.

Maybe with some other crazy stuffs with init files you can patch the framework every boot checking the number of partitions (BTW stop this ot here, someone plz make a thread for this and quote everyone interested :) )

this isn't really offtpic because it's about bootloader features. and no, framework isn't something u can easily patch because apktool needs java and even if it would be written in C you'd mess with signatures. Especially on MIUI this would be a problem.

What about VRTheme? It uses edify/bash to decomplie, apply changes and recompile fw and apps

With init scripts when booting system you can do this

EDIT: @M1cha see here
Code:

# let us copy each original APK here first.

busybox mkdir -p /data/vrtheme-backup/system/app

# Do not remove the credits from this, it's called being a douche
echo "VillainTheme is done"
# we are all done now
With this you need only 4 files [this script, a new storage_list.xml, zip and zipalign)

I just think that the bootloader shouldn't make permanent change sto the system so it will still work if you take a backup and install it to a device without this bootloader. I think I'll stay with the xposed method.
