IXP4xx hardware definitions — Details on obtaining hardware definitions for IXP4xx
Register definitions
The file <cyg/hal/hal_ixp425.h> can be included from
application and eCos package sources to provide definitions related to IXP4xx
subsystems. These include register definitions for the PCI bus controller,
SDRAM controller, DDR controller for IXP46x, expansion bus controller,
I²C® controller for IXP46x, General purpose I/O (GPIO), interrupt
controller, general-purpose timers and watchdog timer.
I/O Definitions
The file <cyg/hal/var_io.h> contains definitions
used by the PCI support, as well as memory mapping details and macros
to read and write the I/O space (including the PCI I/O space) at a variety
of widths. If PCI IDE support has been enabled, it also provides the relevant
support macros.
