In my variant on bootldr, I use a small yaffs partition to house a linux =
zImage. This has a very rapid mount time and low ram footprint. This =
could be a way of lightening the initial ram burden if you are using =
yaffs-direct before booting an os.
If you are severely ram cramped and/or not booting an os then I guess =
you could split the nand up into small partitions and mount/unmount each =
one as needed. Its a bit clumsy but its an option.
