The current write implementation is quite simple: remove existing clusters and then allocating new ones and filling them with data. This, inevitably, enforces always writing from the beginning of a file.
As the first step to lift this restriction, fat_file_write() and set_contents() are modified to accept an additional parameter, file offset and further re-factored so that, in the next patch, all the necessary code will be put into set_contents().

My fatwrite, fatload and compare tests are failing in MMC with this commit. This is what I see:
=> fatwrite mmc 0 ${loadaddr} test 0x2000000 33554432 bytes written => fatload mmc 0 84000000 test 33554432 bytes read in 2149 ms (14.9 MiB/s) => cmp.b 82000000 84000000 0x2000000 byte at 0x820c5000 (0x85) != byte at 0x840c5000 (0x9d) Total of 806912 byte(s) were the same =>
Reverting this commit fixes this issue for me.
Thanks, Faiz
