X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=54cc0dd036bba10b528be0765f5c7f3443a10073;p=thirdparty%2Fu-boot.git

arm: zynq: Enable debug_uart_init in spl when enabled

In past this code was commented and was used for debug purpose.
But there is no reason not to enabled it based on macros.
