Clock configuration
Must match the frequency of the FPGA bitstream (GRMON `info sys` reports the actual AHB frequency). The ACLINT mtime counter runs at half of it.
#define	CLOCK_CORECLOCK (40000000UL)
	CPU core clock, 40 MHz.

Timer configuration
One timer via RISC-V ACLINT (CLINT). CLINT base address is defined in cpu_conf.h (0xe0000000).
#define	TIMER_NUMOF (1)

GPIO configuration
grmon: gpio0 APB: ff983000 - ff983100
#define	GPIO0_BASE_ADDR (0xff983000UL)
	GRGPIO base address.

UART configuration
grmon: uart0 APB: ff900000 - ff900100 IRQ: 1 SW3 = 0: UART0 routed to RIOT application SW3 = 1: UART0 routed to debug (GRMON)
#define	UART0_BASE_ADDR (0xff900000UL)
	APBUART0 base address.

#define	UART0_IRQ (1U)
	APBUART0 PLIC interrupt line.

#define	UART_NUMOF ARRAY_SIZE(uart_config)

static const uart_conf_t	uart_config []

GRETH Ethernet configuration
grmon: greth0 APB: ff984000 - ff984100 IRQ: 5
#define	GRETH_PARAM_BASE (0xff984000UL)
	GRETH base address.

#define	GRETH_PARAM_IRQ (5U)
	GRETH interrupt line.
