* for a bootloader as small and simple as possible. Instead of worring about

- * (1) most pages are 4096 bytes
+ * (1) most pages are 4096 bytes
* (2) version numbers are somewhat sorted in acsending order
* (3) multiple compressed blocks making up one page is uncommon
*
*
* You still should have paper bags at hand :-(. The code lacks more or less
* any comment, and is still arcane and difficult to read in places. As this
- * is incompatible with any new code from the jffs2 maintainers anyway, it
- * should probably be dumped and replaced by something like jffs2reader!
