- * 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 this file.
- * 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_*_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.
