"""
Patch ESP32 QEMU source to fix WiFi/RF peripheral register stubs.
Two changes only — no new files, no meson.build modifications:
1. hw/misc/unimp.c — change unimp_read to return 0xFFFFFFFF instead of 0.
The ESP32 WiFi library busy-loops on hardware-ready bits. With the
default return-0 those loops never exit and the watchdog fires.
0xFFFF... sets all bits, so most active-high "ready/done" flags pass.
2. hw/xtensa/esp32.c — add create_unimplemented_device() calls for all
unmapped WiFi/RF peripheral registers that cause LoadStorePIFAddrError.
