Cover letter [U-Boot] [PATCH v5 0/6] Iotrace improvements
These set of patches add few improvements to iotrace.
* Region limiting - allows setting an address and size where only
io operations that falls into that address are logged.
* Timestamping - Timestamp every iotrace record with current timestamp
* dumping - iotrace dump command for dumping all records from buffer
in a readable fashion.
In terms of backwards compatibility, the timestamp is not backward compatible as it changes the iotrace record. so if one developed an offline parsing tool it will be broken.
I though of adding #ifdef specific for that, but eventually I didn't.
Changes in v5:
- Removed common.h include that caused werid compliation problems in other boards (trini)
- Fixed portability issue in printf (trini)
Changes in v4:
- Resend complete patchset with patman
Changes in v3:
- fixed wrong usage of WARN_ONCE
Changes in v2:
- introduced needed_size to notify the user about the needed buffer size.
Changes in v1:
- Change timestamp function to get_ticks()
