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.

2c6ab8579a esp32: Pass memory layout linker script through C preprocessor
C preprocessor is a bit icky, but with ULP we will have 3 possible
variables influencing the memory layout and 9 linker scripts is too
many!

7c494055e3 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.
