Reminds me of an issue I encountered in my orion5x ide support patch 
series where I also had modified a rather complex condition in 
cmd_ide.c, which determined whether swapping I/O byte reads was needed.

Wolfgang had asked me to replace with a condition on a single new 
CONFIG_IDE_SWAP_IO macro, which in turn had to be defined in various 
cpu, SoC or board config files.

The patch is there: 
<http://article.gmane.org/gmane.comp.boot-loaders.u-boot/82109/match=ide>

Maybe the same principle could apply here?

Amicalement,
