Description

New hardware with instead of a ESP32-WROOM-32E a ESP32-MINI-1, gives me 2 extra IO pins which come in handy.
I want the existing software to detect the new module/chip with ESP.getChipModel(), so it can configure the correct I/O based on the detected chip.
When programming, the chip is correctly identified, and everything is working fine.

esptool.py v4.5.1
Serial port COM3
Connecting.........
Chip is ESP32-U4WDH (revision v3.1)

But when i use ESP.getChipModel() in my code, the wrong Chiptype is reported: ESP32-PICO-D2
When browsing through the Arduino code (Esp.cpp) i see that there is no mention anywhere of the ESP32-U4WDH chip..

Sketch

Serial.printf("ESP32 Chip model:%s\n",ESP.getChipModel());

Debug Message

ESP32-WROOM-32 module:
ESP32 Chip model:ESP32-D0WD-V3 

ESP32-MINI-1 module:
ESP32 Chip model:ESP32-PICO-D2

Other Steps to Reproduce

No response

I have checked existing issues, online documentation and the Troubleshooting Guide

Older versions of the software don't know about newer chips. What does v3.0.7 show for the chip model?

2.0.17 does have the correct chiptype in it's headers already.
A fix would be to replace

arduino-esp32/cores/esp32/Esp.cpp

Line 277 in c7022ca

case EFUSE_RD_CHIP_VER_PKG_ESP32PICOD2: return "ESP32-PICO-D2";

with
case EFUSE_RD_CHIP_VER_PKG_ESP32U4WDH: return "ESP32-U4WDH";

EFUSE_RD_CHIP_VER_PKG_ESP32U4WDH is already defined here:
