Note: Alfawise screens use various TFT controllers. Supported screens are based on the ILI9341, ILI9328 and ST7798V. Define init sequences for other screens in u8g_dev_tft_320x240_upscale_from_128x64.cpp

If the screen stays white, disable 'LCD_RESET_PIN' to let the bootloader init the screen.

Setting an 'LCD_RESET_PIN' may cause a flicker when entering the LCD menu because Marlin uses the reset as a failsafe to revive a glitchy LCD.

Note: Alfawise U20/U30 boards DON'T use SPI2, as the hardware designer mixed up MOSI and MISO pins. SPI is managed in SW, and needs pins declared below.
