From 9e1cc9679776f5b9e42481d392b1550753ebd084 Mon Sep 17 00:00:00 2001 From: Joel Stanley Date: Tue, 22 Sep 2020 16:12:34 +0930 Subject: ARM: dts: aspeed: s2600wf: Fix VGA memory region location The VGA memory region is always from the top of RAM. On this board, that is 0x80000000 + 0x20000000 - 0x01000000 = 0x9f000000. This was not an issue in practice as the region is "reserved" by the vendor's u-boot reducing the amount of available RAM, and the only user is the host VGA device poking at RAM over PCIe. That is, nothing from the ARM touches it. It is worth fixing as developers copy existing device trees when building their machines, and the XDMA driver does use the memory region from the ARM side.
