Setting up the .data and .bss section happens in arm7_init.c now.
The code was commented out anyway, so just remove it.
Also remove leftover variable declarations that were only used in
the dead code.
According to the schematics user button should be on `PD5` not `PC5`
(so `GPIO_PIN(3, 5)`).
Due to the super high values resistors being used for the external
pullup it seems if you use a internal pullup it doesn't work.
The Sub-GHz Antenna of the Openmote-B is always connected to the AT86RF215.
It is the 2.4 GHz radial that can be switched between the CC2538 and the AT86RF215.
This changes the name of the defines accordingly.
To reduce the information that are printed at the console during the startup, special bootloaders are required that suppress the outputs which are only informational. The according bootloader has to be selected during the make process.
Startup information, including board configuration, is only printed when module esp_log_startup is used. This reduces the amount of information that is printed by default to the console during the startup. The user can enable module esp_log_startup to get the additional startup information.
When CCACHE_BASEDIR variable is set, ccache rewrites absolute paths into
relative paths before computing the hash that identifies the compilation
for all the paths under that directory.
The problem is that those paths are also used when the compiler is
called, so the generated dependency files (*.d) will have a relative
path to the object files, and thus, it will not match our rule for
compiling (we use absolute paths). As dependency files define the
targets this way, any change on its dependencies (e.g. an included
header file) will not re-trigger a build.
- Added the file to `riot.doxyfile`
- Shortened the header to display properly
- Added `[TOC]` to let doxygen create a table of contents
- Added manual anchors to the headers for consistency with other doc files
- Use @code and @endcode for code blocks (using fenced blocks doesn't parse
with the Doxygen version used by the CI)
- Changed a numbered list containing code blocks to regular text, as the code
blocks as list items are not parsed correctly
- Enforce 80 chars per line limit
- Fixed some typos
- Removed trailing whitespace
- Added markdown syntax for code highlight in two cases
- Reduced the TODO section heading from level 1 to level 2

lpc23xx has 2k of battery RAM that is retained in Deep Power Down mode.
To not overwrite that data it must only be initialized on Power On Reset.
However, RSIR looks the same when waking up from Deep Power Down as it does
on the power-on case.
So use 4 bytes of the backup RAM to keep a signature that is only valid if
memory was retained (no power-on Reset).
A small change to the linker script is required so two sections can be
placed into flash.
The application is mainly to compile-test non-blocking UART
functionality, but some functional testing is also possible.
With non-blocking UART the total runtime of the program is 2100735 µs
on same54-xpro.
With blocking UART the total runtime is 2152407 µs.
