NAME

ia64_pci_legacy_read - read from legacy I/O space

SYNOPSIS

"SYNOPSIS"

int ia64_pci_legacy_read (struct pci_bus * bus, u16 port, u32 * val, u8 size);

ARGUMENTS

bus: bus to read
port: legacy port value
val: caller allocated storage for returned value
size: number of bytes to read

DESCRIPTION

Simply reads size bytes from port and puts the result in val.

Again, this (and the write routine) are generic versions that can be overridden by the platform. This is necessary on platforms that don't support legacy I/O routing or that hard fail on legacy I/O timeouts.
