    fs/fat/fat_write: Fix management of empty files · 1254b44a
    Benoît Thébaudeau authored
    Overwriting an empty file not created by U-Boot did not work, and it
    could even corrupt the FAT. Moreover, creating empty files or emptying
    existing files allocated a cluster, which is not standard.
    Fix this by always keeping empty files clusterless as specified by
    Microsoft (the start cluster must be set to 0 in the directory entry in
    that case), and by supporting overwriting such files.
