* 2) If > 64MB of memory space is required, the IXP4xx can be configured
* to use indirect registers to access PCI (as we do below for I/O
* transactions). This allows for up to 128MB (0x48000000 to 0x4fffffff)
- * of memory on the bus. The disadvantadge of this is that every
+ * of memory on the bus. The disadvantage of this is that every
* PCI access requires three local register accesses plus a spinlock,
* but in some cases the performance hit is acceptable. In addition,
* you cannot mmap() PCI devices in this case.
* fallback to the default.
