/*
* The Orion has fully programable address map. There's a separate address
* map for each of the device _master_ interfaces, e.g. CPU, PCI, PCIE, USB,
* Gigabit Ethernet, DMA/XOR engines, etc. Each interface has its own
* address decode windows that allow it to access any of the Orion resources.
*
* CPU address decoding --
* Linux assumes that it is the boot loader that already setup the access to
* DDR and internal registers.
* Setup access to PCI and PCI-E IO/MEM space is issued by core.c.
* Setup access to various devices located on the device bus interface (e.g.
* flashes, RTC, etc) should be issued by machine-setup.c according to
* specific board population (by using orion_setup_cpu_win()).
*
* Non-CPU Masters address decoding --
* Unlike the CPU, we setup the access from Orion's master interfaces to DDR
* banks only (the typical use case).
* Setup access for each master to DDR is issued by common.c.
*
* Note: although orion_setbits() and orion_clrbits() are not atomic
* no locking is necessary here since code in this file is only called
* at boot time when there is no concurrency issues.
