Argh... I forgot to create patches with xxx/nnn notation...
Here is the order of patches:
0001-jffs2-add-sector_size-field-to-part_info-structure.patch
0002-jffs2-rewrite-jffs2-scanning-code-based-on-Linux-on.patch
0003-jffs2-summary-support.patch
0004-jffs2-fix-searching-for-latest-version-in-jffs2_1pa.patch
0005-jffs2-add-buffer-to-cache-flash-accesses.patch
0006-jffs2-cache-data_crc-results.patch
It's the order of changes in my tree and thus it's the simplest way to
apply this patches. But actual dependencies are as follows:
0001 and 0004 don't depend on anything
0002 depends on 0001
0003, 0005 and 0006 depend on 0002
Regards, Ilya.
