Subject: riscv: enable CONFIG_DEBUG_UART by default
X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=e637e455ca766d6b5bea5f4c5b9290ab07c87507;p=u-boot.git

riscv: enable CONFIG_DEBUG_UART by default

Most boards don't enable the pre-console buffer. So we will not see any
early messages. OpenSBI 1.3 provides us with the debug console extension
that can fill this gap.

For S-Mode U-Boot enable CONFIG_DEBUG_UART by default.
