Hi, I have a Cherry Trail laptop with an Atom X5-Z8300. It has a bluetooth chip that needs the r8723bs (coexisting RTL 8723BS wifi and bluetooth). I am using linux-next (20150817) with the r8723bs staging driver and the firmware and utility from https://github.com/lwfinger/rtl8723bs_bt by Larry f

object model here-- just mentioning the possibilities. IMHO, KVPs are good for scalar quantities. But, when we get to nested arrays/structs, we would need a tree-structured data model, such as TLVs or FDTs. Please let me know what you think. Regards, Sundar

Subsequently, an FPGA image is released with an additional metadata field that the upstreamed version does not handle. How will this be handled if the metadata were in FDT or KVP format?

ly addressed with a tool that parses TLVs. Compared to some other proposals: * Compared to DTs, TLVs are OS-independent. * Compared to strings as key-value pairs, TLVs can express structures/arrays, can be validated, etc. So, I suggest we use TLVs to express metadata in image files. Thank you very much, Sundar Nadathur
