[U-Boot] [PATCH 0/3] rockchip: rk3399: spl: Make baudrate and UART configurable

[Philipp Tomsich]

The default configuration for debug output from the RK3399 SPL is
UART2 at 1.5MBaud. While this works reasonably well for the EVB,
custom boards may want to change these settings.

To simplify the enablement (i.e. to use the RS232 connector on our
baseboard and to improve the compatibility with commonly available
RS232-to-UART dongles) for the RK3399-Q7 SoM, we need to make both
the UART and the baudrate configurable.

This patch-series makes CONFIG_BAUDRATE a first-class citizen within
the Kconfig framework (so we can set it via defconfig) and adds the
required iomux support for UART0 in the RK3399 SPL.  Finally, we use
the new infrastructure across the RK3399 config files and defconfigs.
