#### Apply patch to ESP8266 SDK

As `iram` is quite small to fit all the codes but linker tries to put it there.
To force JerryScript codes to be placed at the `irom` section,
need to change the order and tell the linker as below;

```

Second file is to modify `irom` size so that it can hold all the codes and data.
This can be done by giving another `SPI_SIZE_MAP`.
For now, I'll use this manual modification.


#### Need to get setjmp / longjmp

Extract and copy from the SDK.

```
cd ~/harmony/jerryscript/targets/esp8266/libs
ar -xv $SDK_PATH/lib/libcirom.a lib_a-setjmp.o
```
