Fixed memory leak in emac_esp_new_dma function. Polished ESP EMAC cache management. Added emac_periph definitions based on SoC features and improved(generalized) ESP EMAC GPIO initialization. Added ESP EMAC GPIO reservation. Added check for frame error condition indicated by EMAC DMA and created a target test.
soc
The soc component provides hardware description for targets supported by ESP-IDF.
- `xxx_reg.h` - defines registers related to the hardware
- `xxx_struct.h` - hardware description in C `struct`
- `xxx_channel.h` - definitions for hardware with multiple channels
- `xxx_caps.h` - features/capabilities of the hardware
- `xxx_pins.h` - pin definitions
- `xxx_periph.h/*.c` - includes all headers related to a peripheral; declaration and definition of IO mapping for that hardware
