There was for long time no activity in the mpx5xxx area. We need to go further and convert to Kconfig, but it turned out, nobody is interested anymore in mpc5xxx, so remove it. Signed-off-by: Heiko Schocher <hs@denx.de>

Enable U-Boot's command-line functions. This provides a means

config CMD_IOTRACE

bool "iotrace - Support for tracing I/O activity"
|

help
|
|
Provides an 'iotrace' command which supports recording I/O reads and
|
|
writes in a trace buffer in memory . It also maintains a checksum
|
|
of the trace records (even if space is exhausted) so that the
|
|
sequence of I/O accesses can be verified.
|
|
|
|
When debugging drivers it is useful to see what I/O accesses were
|
|
done and in what order.
|
|
|
|
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.
|
|
|
|
In particular, when performing major refactoring of the driver, where
|
|
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.
