Hello,
This is the second version of the patch series adding support for automatic software updates from a TFTP server. V2 adds millisecond granularity of the TFTP timeouts and addresses comments posted to the ML for the first version.
First three patches make some general changes required by the new feature, first one in the Flash subsystem, second and third in the networking code. Then follows a minor clean-up, with the feature proper in fifth patch. Last patch provides minor enhancements to the iminfo output that can become handy when using the new feature.
Please see newly added doc/README.update for more details.
Code has been compile-tested on several ppc, arm and mips targets. The feature itself has been tested on TQM8555 and MPC8555CDS and trab boards.
Note that the second patch might introduce networking issues for boards not conforming to the following two mandatory requirements: - CFG_HZ should be set to 1000 - get_timer() should return milliseconds
An example of such a non-conformant board is the trab, which when run with the networking changes mentioned above indeed exhibits timeouts during TFTP transfers. Also, the default timeouts of the auto-update feature have to be significantly increased for the trab target (CONFIG_UPDATE_TFTP_MSEC_MAX set to 1000000, instead of the default 100).
