It depends. If you download images to the filesystem they end up in the
malloc area, so this should at least be big enough to store a kernel
image. You also can tftp directly to flash, so the malloc space does not
have to be as big as your rootfs.
Normally I put barebox at the end of RAM and use 4-16MB of malloc area.
Please make sure that there is ~4MB of free space at the beginning of
the SDRAM since this is used during start of Linux images.
