| | | | | | | | | | | | SD Simplified specification, as well as other SD and SDIO implemenations I've examined, suggest this disclaimer may be required. It is unclear to me exactly what the license would be for, or why it might be required. Err on the side of caution and include this disclaimer so anybody deploying this code can judge for themselves. I have no further unformation about the details. Notes: svn path=/head/; revision=170002
