Subject: debug_uart: Adjust the declaration of debug_uart_init()
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=97b059730218;p=u-boot.git

debug_uart: Adjust the declaration of debug_uart_init()

We want to be able to add other common code to this function. So change the
driver's version to have an underscore before it, just like
_debug_uart_putc(). Define debug_uart_init() to call this version.

Update all drivers to this new method.
