600 When enabled, additional eeprom sub-commands become available.
601
602 eeprom print - prints the contents of the eeprom in a human-readable
603 way (eeprom layout fields, and data formatted to be fit for human
604 consumption).
605
606 eeprom update - allows user to update eeprom fields by specifying
607 the field name, and providing the new data in a human readable format
608 (same format as displayed by the eeprom print command).
609
610 Both commands can either auto detect the layout, or be told which
611 layout to use.
612
613 Feature API:
614 __weak int parse_layout_version(char *str)
615 - override to provide your own layout name parsing
616 __weak void __eeprom_layout_assign(struct eeprom_layout *layout,
617 int layout_version);
618 - override to setup the layout metadata based on the version
619 __weak int eeprom_layout_detect(unsigned char *data)
620 - override to provide your own algorithm for detecting layout
621 version
622 eeprom_field.c
623 - contains various printing and updating functions for common
624 types of eeprom fields. Can be used for defining
625 custom layouts.

974 Provides an 'iotrace' command which supports recording I/O reads and
975 writes in a trace buffer in memory . It also maintains a checksum
976 of the trace records (even if space is exhausted) so that the
977 sequence of I/O accesses can be verified.
978
979 When debugging drivers it is useful to see what I/O accesses were
980 done and in what order.
981
982 Even if the individual accesses are of little interest it can be
983 useful to verify that the access pattern is consistent each time
984 an operation is performed. In this case a checksum can be used to
985 characterise the operation of a driver. The checksum can be compared
986 across different runs of the operation to verify that the driver is
987 working properly.
988
989 In particular, when performing major refactoring of the driver, where
990 the access pattern should not change, the checksum provides assurance
991 that the refactoring work has not broken the driver.
992
993 This works by sneaking into the io.h heder for an architecture and
994 redirecting I/O accesses through iotrace's tracing mechanism.
995
996 For now no commands are provided to examine the trace buffer. The
997 format is fairly simple, so 'md' is a reasonable substitute.
998
999 Note: The checksum feature is only useful for I/O regions where the
1000 contents do not change outside of software control. Where this is not
1001 suitable you can fall back to manually comparing the addresses. It
1002 might be useful to enhance tracing to only checksum the accesses and
1003 not the data read/written.
