X-Git-Tag: v2017.01-rc1~160 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=88e0d59315f4863537a94f12ef48348764f4316b;p=u-boot vexpress64: Juno: Change PCI buss addresses for IO to start from zero. Juno uses a 1:1 mapping between CPU and PCI addresses for IO. First, that will trip devices that cannot use more than 16 bits of addresses for IO, second it is un-necessary as the system can handle zero-based PCI addresses just fine. Change the mapping to start IO bus addresses from zero.
