I'm not sure how much baggage the Keil File System brings along with it. The sector access method I'd tend to advocate might take a few hundred lines of code layered over some basic sector read functionality. Basically a very simple boot loader, with a minimal read-only, root directory only, FAT16/32, single file reader.
Ideally you'd physically separate the boot loader, and application code, so that the boot loader doesn't get re-written, and sanity checks the app code before running it. The boot loader would provide several recovery paths, as well as pulling an app update from an external device, SD/MMC card, or whatever.
