Problem Details: This patch updates the m66592-udc buffer management code. Use fixed buffers for bulk and isochronous pipes, also make sure to handle the isochronous-as-bulk case. With fixed buffers there is no need to keep track of used buffers with bi_bufnum. Also, this fixes a potential buffer offset problem where...

Problem Details: The @addr passed into pcpu_chunk_addr_search() is unit0 based address and thus should be matched inside unit0 area. Currently, when it uses chunk size when determining whether the address falls in the first chunk. Addresses in unitN where N>0 shouldn't be passed in anyway, so this doesn't cause any m...
