So, it looks like a lot of what Simon did so that we could have more than one environment type compiled in was a step in the right direction. What we should be able to move forward on is being able to link in both FAT and MMC and whatever is found work, along with a Kconfig choice for what should be the default one, or some other way that's not just link order to control that. -- Tom
