commit 2d0c3fbe43fa0e6fcb7a6c755c5f4cd702c0d2f4 upstream.
The Keystone outbound Address Translation Unit (ATU) maps PCI MMIO space in
8 MB windows. When programming the ATU windows, we previously incremented
the starting address by 8, not 8 MB, so all the windows were mapped to the
first 8 MB. Therefore, only 8 MB of MMIO space was accessible.
Update the loop so it increments the starting address by 8 MB, not 8, so
more MMIO space is accessible.
Fixes: e75043ad9792 ("PCI: keystone: Cleanup outbound window configuration")
