Display, U-Boot, and SPI LCD
PICO2 primarily uses an SPI/DBI LCD. Select one matching display stack from DISP, LCD_FB, or FBTFT.

Important panel parameters include driver name, interface type, active resolution, total timing, porches, pixel clock, start delay, and PWM.
U-Boot logo flow:
Enable display driver
→ Configure U-Boot DTS
→ Configure panel and PWM
→ Prepare boot-resource partition
→ Package BMP logo
