ARM: 7793/1: debug: use generic option for ep93xx PL10x debug port
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).
