We use UImage based on squashfs (gzip) in our UImage. U-Boot does not
care what type of file system is in UImage formatted file. It only cares
the file is a proper UImage. If you are looking at any U-Boot commands
to deal with files inside the squashfs image U-Boot does not provide any
such support.
Why don't you try generating cramfs and squashfs etc. based UImage files
using your root file system contents and compare. Here is some date for
you based on our PPC405PR based system which may or might not be
representative.
RAM Memory After Boot:
fs_type available used free
ext2 30724 17636 13088
cramfs 30724 9700 21024
squashfs 30724 9800 20924
File System Size:
fs_type uncompessed gzip bzip2
ext2 11564032 3183668 2922595
cramfs 3805184 3783755 3736662
squashfs 3203072 3182423 3157283
