Subject: serial: ns16550: Allow serial to enabled/disabled in SPL
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=2e2c514a40e956d857707f157201c5606c0e9da0;p=u-boot.git

serial: ns16550: Allow serial to enabled/disabled in SPL

At present this driver uses the wrong condition for including the code and
drivers in SPL/TPL. Update it so that the code is only included if
DM_SERIAL is enabled for SPL/TPL.
