748 help
749 Provides an 'iotrace' command which supports recording I/O reads and
750 writes in a trace buffer in memory . It also maintains a checksum
751 of the trace records (even if space is exhausted) so that the
752 sequence of I/O accesses can be verified.
753
754 When debugging drivers it is useful to see what I/O accesses were
755 done and in what order.
756
757 Even if the individual accesses are of little interest it can be
758 useful to verify that the access pattern is consistent each time
759 an operation is performed. In this case a checksum can be used to
760 characterise the operation of a driver. The checksum can be compared
761 across different runs of the operation to verify that the driver is
762 working properly.
763
764 In particular, when performing major refactoring of the driver, where
765 the access pattern should not change, the checksum provides assurance
766 that the refactoring work has not broken the driver.
767
768 This works by sneaking into the io.h heder for an architecture and
769 redirecting I/O accesses through iotrace's tracing mechanism.
770
771 For now no commands are provided to examine the trace buffer. The
772 format is fairly simple, so 'md' is a reasonable substitute.
773
774 Note: The checksum feature is only useful for I/O regions where the
775 contents do not change outside of software control. Where this is not
776 suitable you can fall back to manually comparing the addresses. It
777 might be useful to enhance tracing to only checksum the accesses and
778 not the data read/written.

1313 from SoC's non-volatile secret key and a 16 bit Key identifier.

1315 blob. The non-volatile secure key is available for use only during
