Default UART and SPI pins

I'm wondering about default UART and SPI pins. Based on bits of info I can find, I'm assuming that the UART default config is as follows:

#define UART1_TX_PORT GPIO_PORT_0
#define UART1_TX_PIN GPIO_PIN_4
#define UART1_RX_PORT GPIO_PORT_0
#define UART1_RX_PIN GPIO_PIN_5
#define UART1_RTS_PORT GPIO_PORT_0
#define UART1_RTS_PIN GPIO_PIN_3
#define UART1_CTS_PORT GPIO_PORT_0
#define UART1_CTS_PIN GPIO_PIN_2

That is from periph_setup.h in the DSPS example. Those pins seem to work for Smart Snippets just fine.

Are there any default SPI pins? IOW, ones that work after the Dialog boots, but there is no code on the device (OTP, Flash, etc.)?

Thanks.
