[MTD][NOR] Add physical address to point() method

2008-05-01T17:59:11+00:00

Adding the ability to get a physical address from point() in addition
to virtual address.  This physical address is required for XIP of
userspace code from flash.

[JFFS2] Track parent inode for directories (for NFS export)

2008-05-01T17:47:17+00:00

To support NFS export, we need to know the parent inode of directories.
Rather than growing the jffs2_inode_cache structure, share space with
the nlink field -- which was always set to 1 for directories anyway.

[JFFS2] Handle dirents on the flash with embedded zero bytes in names.

2007-10-13T10:35:58+00:00

In three places: summary scan, normal scan, REF_PRISTINE GC.

Just truncate at the NUL, since that was the correct thing to do in the
only case where this (inexplicable) breakage has been seen.

[JFFS2] Fix unpoint length

2007-09-23T17:41:17+00:00

Fix a couple of instances in JFFS2 where the unpoint() routine is
being called with the wrong length in cases where the point() routine
truncated a request.

[JFFS2] Whitespace cleanups.

2007-07-10T09:01:22+00:00

Convert many spaces to tabs; one or two other minor cosmetic fixes.

[JFFS2] Deletion dirents should be REF_NORMAL, not REF_PRISTINE.

2007-06-29T12:39:57+00:00

Otherwise they'll never actually get garbage-collected.

[JFFS2] Tidy up licensing/copyright boilerplate.

2007-04-25T13:16:47+00:00

In particular, remove the bit in the LICENCE file about contacting
Red Hat for alternative arrangements. Their errant IS department broke
that arrangement a long time ago -- the policy of collecting copyright
assignments from contributors came to an end when the plug was pulled on
the servers hosting the project, without notice or reason.

We do still dual-license it for use with eCos, with the GPL+exception
licence approved by the FSF as being GPL-compatible. It's just that nobody
has the right to license it differently.

[JFFS2] Better fix for all-zero node headers

2007-04-25T03:13:06+00:00

No need to check for all-zero header since the header cannot
be zero due to other checks.

Replace the all-zero header check in readinode.c with a
check for the magic word.

[JFFS2] Speed up mount for directly-mapped NOR flash

2007-04-17T18:07:34+00:00

Remove excessive scanning of empty flash after a clean
marker for users of the point/unpoint method. cfi_cmdset_0001
uses point/unpoint by default iff flash mapping is linear.
The speedup is several orders of magnitude if FS is less than
half full.
