From 24956642ef7de5d8340683d721113f993ffaa0a8 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Remove unused CONFIG_SERIAL_SOFTWARE_FIFO feature
This patch removes the completely unused CONFIG_SERIAL_SOFTWARE_FIFO
feature from U-Boot. It has only been implemented for PPC4xx and was not
used at all. So let's remove it and make the code smaller and cleaner.
