Okay. Thanks for your confirmation!

May we keep the flat directory structure for UCM files?

For the same manufacturer, its DMI vendor name could change, e.g. "Intel 
Inc." or "Intel Corporation". In addition, there may be changes caused 
by using upper case or low case characters. Since we don't want to 
maintain a mapping table and just do verbatim copy of DMI info, it's 
hard to group all the products/boards of one manufacturer into one UCM 
directory. So I feel it may be better to keep the simple flat directory 
structure.

Thanks
