I am not an expert on ARM7/ARM9 differences but there are several eCos
maintainers who have experience with multiple ARM variants and are well
positioned to review the AT91SAM9 patch. I do not think motivation
should be an issue here. We all wish to see eCos move forward and
AT91SAM9 support is clearly very good for the project.
My main concern is that we don't break eCos support for older ARM
platforms in the process of improving the hardware abstraction for
future platform ports.
Is there an eCos maintainer with the necessary ARM expertise who can
volunteer for the review of this contribution? Ref:
