Hi, This series convert reservation of Loongson64 Logic PIO into DeviceTree based method. It can be used to replace Huacai's "MIPS: Loongson64: Reserve legacy MMIO space according to bridge type". Thanks. v2: - Address Rob and Huacai's review comments. v3: - Address Rob, Thomas's review comments. v4: - Fix typo & grammar issue according to Xuerui's suggestion.
