Turn on _FS_NORTC: This means we don't have to implement get_fattime() which simplifies life for now.
Automatically set _FS_READONLY based on CONFIG_FAT_WRITE. This requires including <config.h> since we reference CONFIG_*.
Set _USE_LFN to enable long filename handling; an essential feature.
Set _FS_RPATH so that paths components "." and ".." are correctly parsed and handled. This enables paths such as "/extlinux/../foo" to work.
Set _USE_LABEL so that volume labels can be read.
Hmm, is there some way to wrap volume label support in Kconfig? I'm sure this is useful in some cases, but maybe something that boards that are already on the cusp of their size limit would want off?
It's certainly possible; ffconf.h's definition of _FS_READONLY is already driven by CONFIG_FAT_WRITE in this series.
I'm not sure if it's worth it though; on the RPi, turning off volume label support only saves ~0.5K of .text, 0 .data, and 8 bytes .bss. If so, I can certainly throw in another patch to allow it to be configured.
