Introduce netdev IOCTLs, to be used by the debug tools. Allows to read/write single dword value or memory block, aligned to dword Different address modes supported: - BAR offset - Firmware "linker" address - target's AHB bus Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W.
