The kernel timer on RPI is able to measure time microseconds-precise.
Howeer, due to a bug, we dropped precision during the ticks-to-time
translation and return only milliseconds-precise time.
Ref #2400
As the timer session now provides a method 'elapsed_us', there is no more need
for doing any internal calculations with values of milliseconds.
Ref #2400
As timer sessions are not expected to be microseconds precise (because
of RPC latency and scheduling), the session interface provided only a
method 'elapsed_ms' although the back end of this method in the timer
driver works with microseconds.
However, in some cases it makes sense to have a method 'elapsed_us'. The
values it returns might be milliseconds away from the "real" time but it
allows you to work with delays smaller than a millisecond without
getting a zero delta value.
This commit is motivated by the need for fast bursts of calibration
steps for the time interpolation in the new timer connection.

The filename buffer of a dataspace in base-linux is limited to
40 bytes. When using file names longer than this, the remainder
gets dropped silently. Add an error message to aid debugging this
case.
This is helpful for disabling messages in etc/tools.conf by
setting it to e.g.
MSG_LINK = @true ""
This results in much shorter and less cluttered logs in automatic
builds.
- factor out Rm_client::pager lambda code into utility
Region_map_component::create_map_item
- use utility to find/lookup physical addresses to be mapped eagerly
Issue #2209
The launcher.run scenario was last updated mid-may of the recently
developed cap-quota accounting (before all cap types were covered).
Hence, the quotas used in the scenario are too low. This patch adjusts
the values such that the scenario can be started on NOVA on Qemu. It
also fixes a warning about a deprecated way of configuring the
report_rom component.

- Update FatFS port from 0.07e to 0.13
- Multi-device support
- Basic test at run/fatfs
- Adaption of existing components
Note, ffat is now consistently renamed to fatfs.
Ref #2410
rm_fault.run triggers write on read-only ROM provided by core, which
fails without this patch:
arm - "raised unhandled data abort"
x86 - (silent/invisible) busy loop because write fault gets never resolved
The run script did not consider the routing for the environment ROM
sessions for the test-iso component. It routed all ROM sessions -
including the ones for the executable and the dynamic linker - to
fs_rom. The patch also adds the cap quota definitions required since
version 17.05 and fixes a whitespace inconsistency between the test
program and the run script.
Thanks to Steven Harp for reporting!
