chenwei c4595d2504 feat(file system): add memory-based romfs 
1, this RomFS's codebase is Nuttx romfs, then it is compatible with
Linux RomFS and you can create such a file system using the tool genromfs.
2, there are two major changes against with the original Nuttx romfs:
    1), it is memory-based: all contents of the fs are stored in the
        memory in the very first stage of "mount".
    2), this version of romfs is altered to be compatible with our new
        version of VFS to take advantage of vnode cache and path cache.

zhOu f76fa4a344 feature: support ipc copy fd to process 2021-05-11 14:56:09 +08:00
Far 9503c4a9fc fix: statfs can't get f_bfree and f_bavail of a FAT12/FAT16 partition 
FAT12/FAT16 partition has no FSINFO sector storing the free cluster number,
so scanning the FAT is necessary to get the free clusters nums.
