1139 In particular, when performing major refactoring of the driver, where
1140 the access pattern should not change, the checksum provides assurance
1141 that the refactoring work has not broken the driver.
1142
1143 This works by sneaking into the io.h heder for an architecture and
1144 redirecting I/O accesses through iotrace's tracing mechanism.
1145
1146 For now no commands are provided to examine the trace buffer. The
1147 format is fairly simple, so 'md' is a reasonable substitute.
1148
1149 Note: The checksum feature is only useful for I/O regions where the
1150 contents do not change outside of software control. Where this is not
1151 suitable you can fall back to manually comparing the addresses. It
1152 might be useful to enhance tracing to only checksum the accesses and
1153 not the data read/written.
