* | [MTD] Support combined RedBoot FIS directory and configuration areaRod Whitby2006-12-081-3/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RedBoot supports storing the FIS directory and the RedBoot configuration area in the same block of flash memory. This is not the most common RedBoot configuration, but it is used on commercially available boards supported by the kernel. A recent patch to mtd/redboot.c (http://lkml.org/lkml/2006/3/20/410) which corrected the skipping of deleted table entries has exposed the latent problem of the kernel redboot parser running off the end of the FIS directory and interpreting the RedBoot configuration information as table entries. This patch terminates the table parsing when the first truly empty entry is found (table entry deletion only clears the first byte of the name, so two cleared bytes in a row indicates the end of the table), thereby supporting the combined redboot FIS directory and RedBoot configuration information flash layout scenario.

* | [MTD] Use EXPORT_SYMBOL_GPL() for exported symbols.David Woodhouse2006-11-291-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While we're fixing up the newly-added symbol, change the neighbouring ones too, for consistency and also to reflect the author's interpretation of the GPL -- which is that _no_ non-GPL modules are permitted. The author always intended his code to be released under the GPL, and believes that any new interpretation of 'EXPORT_SYMBOL' as being any different from 'EXPORT_SYMBOL_GPL' is entirely invalid; the GPL requires that _all_ exports have the semantics of the new 'EXPORT_SYMBOL_GPL', which means the extra four characters are entirely redundant. But since those four extra characters trigger the check for illegal modules in a way that just EXPORT_SYMBOL does not, it's useful to change anyway. This action in no way indicates an admission that there is any legal distinction between the two states, and in particular does not indicate that the author believes that non-GPL modules may use symbols exported with EXPORT_SYMBOL alone.
