This directive tells the compiler that cromfs_node_s might be located at a memory
address which is not word aligned. This resolves the hardFault caused by unaligned
memory access on armv6-m architecture which doesn't support it.
Squashed commit of the following:
tools/gencromfs.c: Seems basically functional but has not has not yet been integrated with CROMFS.
tools/gencromfs.c: Revist previous commit. Let's make no assumptions about the compatibility of the host system and NuttX.
tools/gencromfs.c: I think access mode bits are sufficiently standard that we can just copy them from the host. This is don't mostly to pick up the executable bits and other conbinations of bits without doing a bit-for-bit decode.
tools/gencromfs.c: Code complete but only partially functional.
tools/gencromfs.c: type definitions must precede data definitions
tools/gencromfs.c: Adds a little more logic to gencromfs tools. Still not complete but can traverse directories and generate directory and hard-link nodes.
tools/gencromfs.c: Beginning of a genromfs tool that will eventually be used for generation of CROMFS file system images.
Squashed commit of the following:
fs/cromfs: Now depends on EXPERIMENTAL because it is not yet verified.
fs/cromfs: This commit brings the CROMFS file system to code complete. Still completely untested. Next steps: Need a tool to generate CROMFS file system images and a test case under apps/
fs/cromfs: Add logic to traverse the in-memory file system nodes.
fs/cromfs: Add initial support for an in-memory, compressed, read-only file system.
