Hi Tom, As I know, the CONFIG_BLK is not supported on some platforms' defconfig (# CONFIG_BLK is not set), such as the fsl-qoriq platform. I find when 'CONFIG_BLK=y', then 'fsl-esdhc-mmc' device can't work normally.
So, in order to make sure the NVMe driver is available on all the platforms, I support for both with and without BLK. Thank you!
