[seL4] Implementing a Filesystem on CAmkES

Hello all,

I was hoping to get some advice on how to implement a filesystem on my CAmkES project. For now I'm targeting FAT32, but that is flexible. So far, my plan is to port the libsdhcdriver to my platform (which shouldn't be too bad. I'm targeting exynos5, and I see exynos4 is already supported). After that, I assume I'm on my own when it comes to creating a filesystem interface. Perhaps there is an existing library for this that can hook into any standard SD controller implementation? Finally, is there an easy way to integrate said filesystem into musllibc such that one could use the standard open/read/write/close functions?

Does this sound like the best way to go, or am I missing a simpler solution?

Thanks, Grant
