quick question about TPM

[niek.nooijens at omron.com]

Hi Simon

Driver model is enabled, so it's pretty weird it doesn't show up.
CONFIG_DM=y
CONFIG_SPL_DM=y
CONFIG_DM_WARN=y

The TPM menu is there, yet somehow empty.
This is just after "make socfpga_cyclone5_defconfig" and "make menuconfig"
if I use "make snow_defconfig" the menu is usable like normal, so something is disabling it, yet when grep-ping for TPM in socfpga there are no results.
Adding it to .config manually also doesn't seem to work. so I'm a bit confused about what's going on. Anyhow thanks for the help!

Niek

The only thing 'config TPM' depends on is DM (driver model). Is that
somehow disabled? Once you enable that, it should appear.
