When running qemu/nsh_smp or sim/nsh configuration, run gcov -d /tmp/xxx
to save all gcov generated data and export them to the host. Use
./tools/gcov.sh to parse and generate reports. For details, see:

reason:
up_set_current_regs initially had two functions:
1: To mark the entry into an interrupt state.
2: To record the context before an interrupt/exception. If we switch to
a new task, we need to store the upcoming context regs by calling up_set_current_regs(regs).
Currently, we record the context in other ways, so the second function is obsolete.
Therefore, we need to rename up_set_current_regs to better reflect its actual meaning,
which is solely to mark an interrupt.

After compilation, when starting nsh, the following crash occurs.
==2500151==Shadow memory range interleaves with an existing memory mapping. ASan cannot proceed correctly. ABORTING.
==2500151==ASan shadow was supposed to be located in the [0x1ffff000-0x3fffffff] range.
==2500151==Process memory map follows:
0x30000000-0x33dd4000 /nuttx/nuttx
To avoid overlaps, change the starting address of the text segment.
Using Ttext-segment=0x30000000 causes a crash when starting the 32-bit SIM.
Using -Ttext-segment=0x50000000 causes a crash when starting the 64-bit SIM.
Setting -Ttext-segment=0x40000000 resolves all issues perfectly.

Adds ADC support with minimal feature set (no DMA or Timers etc). A new nucleo-h563zi configuration was added to
provide easy testing with the adc example NSH addon.

Split nucleo-f4x1re into nucleo-f401re and nucleo-f411re.
These are separate boards and should be in separate directories as it's
done for all other nucleo boards in NuttX
