The mach/io.h header on at91 is used to support a nonstandard I/O space window for the cf card driver. This changes the driver to use pci_ioremap_io in order to have the standard location, and then removes the custom mach/io.h.

|
On AT91rm9200 chips where you're using a system clock derived
|
|
from the 32768 Hz hardware clock, this tick rate should divide
|
|
it exactly: use a power-of-two value, such as 128 or 256, to
|
|
reduce timing errors caused by rounding.
|
|
|
|
On AT91sam926x chips, or otherwise when using a higher precision
|
|
system clock (of at least several MHz), rounding is less of a
|
|
problem so it can be safer to use a decimal values like 100.
