Enable U-Boot's command-line functions. This provides a means
|
|
to enter commands into U-Boot for a wide variety of purposes. It
|
|
also allows scripts (containing commands) to be executed.
|
|
Various commands and command categorys can be indivdually enabled.

Depending on the number of commands enabled, this can add

Even if the individual accesses are of little interest it can be

useful to verify that the access pattern is consistent each time

an operation is performed. In this case a checksum can be used to

characterise the operation of a driver. The checksum can be compared

across different runs of the operation to verify that the driver is
|
|
working properly.

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