Jiaxun Yang 191edae40a MIPS: Loongson64: Enable DMA noncoherent support ... commit edc0378eee00200a5bedf1bb9f00ad390e0d1bd4 upstream. There are some Loongson64 systems come with broken coherent DMA support, firmware will set a bit in boot_param and pass nocoherentio in cmdline. However nonconherent support was missed out when spin off Loongson-2EF form Loongson64, and that boot_param change never made itself into upstream. Support DMA noncoherent properly to get those systems working.
