a2c5cb729a fs:support zipfs,can mount zipfile
we can mount a zipfile in nuttx use mount command like this:

mount -t zipfs -o /data/test.zip /zip

The zipfs is a read only file system,The advantage is that it
does not occupy additional space when reading the decompressed file.

When used, reading and decompression operations are simultaneous.
The known disadvantage is that when using seek to read forward,
it will reopen and cause slow speed problems.

VELAPLATFO-12536

This provides the initial hooks for Flattened Device Tree support
with QEMU RV. It also provides a new procfs file that exposes the
fdt to userspace much like the /sys/firmware/fdt endpoint in Linux.
See https://www.kernel.org/doc/Documentation/ABI/testing/sysfs-firmware-ofw

Nodes in the fdt are not yet usable by the OS.

bfeb73e850 fs/tmpfs: fix use after free issue
mmap establish a mapping address space that refer to a tmpfs file,
there are two issues:

1. if the tmpfs file is removed and a subsequent close(), tmpfs_close
will release the backend memory object, use after free errors occur
when operating the mapping memory. We add an extra reference to memory object,
memory will be released when there are no more mappings.

2. if unmap only a portion of the memory, fix the bug that adds another map.
Use realloc and shrink the mapping memory instead.

The fix pass LTP posix case mmap/10-1.c and mmap/12-1.c
