    ARM: 7793/1: debug: use generic option for ep93xx PL10x debug port · d2c215aa
    Hartley Sweeten authored
    The generic option DEBUG_LL_UART_PL01X is now used to select the UART
    type for the kernel low-level debugging on the ep93xx platform. This
    enables two config options to provide the physical and virtual base
    address of the debug UART.
    
    Use the generic options instead of providing platform specific options
    to select the debug UART.
    
    UART1 is selected with:  DEBUG_UART_PHYS = 0x808c0000
                             DEBUG_UART_VIRT = 0xfedc0000
    
    UART2 is selected with:  DEBUG_UART_PHYS = 0x808d0000
                             DEBUG_UART_VIRT = 0xfedd0000
    
    UART3 is selected with:  DEBUG_UART_PHYS = 0x808e0000
                             DEBUG_UART_VIRT = 0xfede0000
    
    The selected UART must already be initialized by the bootloader. If it
    isn't setup nothing will appear (which might be desired).
