Add support for Renesas "Stout" development board based on
R-Car H2 SoC which has SCIFA compatible UART.
Actually existing SCIF UART support (debug-scif.inc) and
newly added SCIFA UART support (debug-scifa.inc) differ only
in registers offsets.
Can we try to merge the two then? One solution is to provide another
options similar to how we deal with REG_SHIFT on the 8250.
Actually, the main difference for the "early printk" support is in two
reg offsets:
+#define SCIFA_SCASSR 0x14 /* Serial status register */
+#define SCIFA_SCAFTDR 0x20 /* Transmit FIFO data register */
+#define SCIF_SCFSR 0x10 /* Serial status register */
+#define SCIF_SCFTDR 0x0c /* Transmit FIFO data register */
I am not mistaken, we will have to introduce two options to cover this
case, as the offsets are not correlated with each other, no?
