I don't know :( It took me days to find this U-Boot dependency, thanks to Troy helping with this! I enabled SGTL5000 sound in the kernel and it didn't work. Until I found that it works with the ER5 Freescale U-Boot, but not with the recent mainline one. It seems to me that the SGTL5000 kernel feature for the SabreLite was developed with a Freescale U-Boot (patching the kernel with DT append) and not tested with the mainline U-Boot.
