There has been no response to this. The review of Evgeniy's patch is particularly important at present to avoid merging issues for various new and planned platform ports on ARM7/9. It is also important that the variant abstraction re-work is reviewed by someone with real expertise in the area. What do you suggest? Should we ask for a volunteer from the wider eCos community to review the patch in this instance? John Dallaway eCos maintainer
