ESP32 has two banks of size 192K and 128K which can be used
as DRAM, system heap allocates area from region 0.
This configuration can be used to add memory from region 1
to heap and can be allocated using k_malloc.
config ESP32_DEEP_SLEEP_WAKEUP_DELAY
int "Extra delay in deep sleep wake stub (in us)"
default 2000
range 0 5000
help
When ESP32 exits deep sleep, the CPU and the flash chip are powered on
at the same time. CPU will run deep sleep stub first, and then
proceed to load code from flash. Some flash chips need sufficient
time to pass between power on and first read operation. By default,
without any extra delay, this time is approximately 900us, although
some flash chip types need more than that.
By default extra delay is set to 2000us. When optimizing startup time
for applications which require it, this value may be reduced.
If you are seeing "flash read err, 1000" message printed to the
console after deep sleep reset, try increasing this value.

Hidden option to enable the ESP32 Ethernet MAC driver.
Both Ethernet and MDIO depend on this driver.
