Initramfs is not a read-only "ROM" fs but a compressed writable fs. Once expanded it will take more memory. To lower memory usage for embedded usage of our devices we've added a method to embedded cramfs/squashfs file systems into the kernel image.
Why not just run the cramfs/squashfs on a standard mdtblock device?
I've made sure it was unobtrusive and that no linker script changes, etc. were required.
