chronos is indirectly blacklisted because of missing periph_uart feature.
hamilton doesn't provide periph_uart when stdio_rtt is disabled (because
of ethos dependency to stdio_uart) and ruuvitag/thingy52 provide the
periph_uart feature so stdio_uart can work on these boards.
- Define test_utils_interactive_sync as DEFAULT_MODULE in Makefile.tests_common
- For tests disabling autoinit, add test_utils_interactive_sync to main
- Add DISABLE_MODULE += test_utils_interactive_sync for tests requiring
sudo, `tests/shell`, `tests/minimal` and `tests/stdin`
- Add shell_commands to tests/periph_wdt and tests/struct_tm_utility to
pull `r` and `s` commands
- Remove includes and usage in `tests/main.c` for tests that where
already using test_utils_interactive_sync
The mips-malta board is a maintainance burden, has no working UART input
and is unobtainable and thus must be removed.
1. Unobtainable board
=====================
The mips-malta board is not an off-the-shelf part. A quick web
search only show the MIPS website where one is told to "contact sales".
I could find it on ebay, used, at €155 and from single seller.
Not having access to the board means:
a. We cannot maintain it. In fact it could be broken right now.
b. Potential RIOT uses have not access to the board either. In other
words, it is pointless to run on hardware nobody has.
2. No working UART input
========================
Not all applications need UART input, but that is no excuse for not supporting
it:
a. Makes development & debugging way harder.
b. It is impossible to run interactive tests.
b.1. Constrains the rest of the platforms by providing an incentive to not
make tests interactive.
c. The lack of UART is a witness to the poor quality of the port.
I want to stress point (c). If something as basic as a serial port cannot work,
how can we expect more complex fucntionality to work. The answer is impossible
to know, because of point (1).
3. Maintainance burden
======================
The RIOT project has limited time and human resources which can be better spent.
a. Compiling for mips-malta wastes CPU time.
b. Blacklisting the board in the test wastes contributor's time.
c. Adapting the board's makefile during build system rework takes time and makes
the reworks harder.
c.1. Add to that that the changes are most of the time not even tested on the board
because of (1). Look at the github issues/PRs and you will see it.
d. Developers usually stick to the lowest common denominator. Issue (2) sets this
denominator unacceptably low.
MIPS platform in general
========================
In commits I will address general issues in the MIPS platform and why it should all
be removed.
Added arduino-nano to BOARD_INSUFFICIENT_MEMORY/BOARD_BLACKLIST following suit
of how arduino-uno is marked, as arduino-nano is mostly an Uno in a different
form factor.
Use a minimalistic dummy instead of the default interface for testing
the `gnrc_ipv6_ext` module.
Currently the default interface is used which leads to problems with
this test, since random traffic on the medium or a missing default
interface might lead to failed results.
Since the `tap` dependency is removed for `native`, I add this test for
testing on CI.
