Why would you need to update the FIS dir? After all, the skip regions
I was thinking of the following method:
- take the new kernel, check the size
- if it's larger thab 1 MB, check whether mtd has a Kernel1 and Kernel2
a) Take the size of Kernel1 from /proc/mtd (-16 byte for the header),
split the kernel and write it to Kernel1 and the rest to Kernel2.
b) Write the kernel to Kernel
- write the ramdisk to Ramdisk

Just ping me and I'll respond if I'm around.
