Add Comments
Modify spinlock error in periph_ctrl.c
Define xcoreid offset, add warning in tcb struct wrt the need to also change that define when struct changes

>1000Hz breaks portTICK_PERIOD_MS (see gitlab 4)
A working >1000Hz tick rate is possible with some changes, but beyond a
certain point it's dimishing returns to preempt tasks this often.
lwip/esp32: support iperf
1. Add _exit() definition in syscalls.c
2. Fix a bug in sockets.c on which iperf depends
I'm now investigating performance of esp32, need iperf to be merged in to master branch for convience
See merge request !136
1. add libphy.a librtc.a, but store in bt submodule, if someone use them, please copy to esp32/lib/ instead the origin one
2. add 07_blufi demo
3. change esp32/Kconfig to allow bt/wifi coexist
syscall write: Should return number of bytes written
Fixes bug where sometimes output truncates after a newline, or large
chunks of large output buffers are lost.
Closes#44
See merge request !133
add smartconfig header files(merge this after updating libsmartconfig.a version v2.6.2)
1. change the API names.
2. return esp_err_t
3. merge this after updating libsmartconfig.a version v2.6.2

esp32: Bootloader wake deep sleep stub
App can contain a stub program resident in RTC fast memory. Bootloader
will load the stub on initial boot. If the device wakes from deep sleep,
the stub is run immediately (before any other data is loaded, etc.)
To implement a custom wake stub, implement a function in your program:
```
void RTC_IRAM_ATTR esp_wake_deep_sleep(void)
{
esp_default_wake_deep_sleep();
// other wake logic
}
```
... and it will replace the default implementation.
See merge request !78
We reserve 4KB Slow RTC memory to save RF calibation result and BT NVS data.
If not all these Slow RTC momory Blocks are used, we will open the other parts.
Workaround: Automatically pin no-cpu-affinity task to a core when FPU is used
FPU status at the moment does not migrate cleanly between cores, so tasks without affinity that happen to migrate across FPUs will run into problems. As a workaround, this modification will automatically pin the task to the current CPU when FPU activity is detected. If anything, it's better than getting all kinds of weird and wonderful FPU corruption issues...
