TLDR: In the configuration SPL_MXC_OCOTP, the dependency on SPL_MISC should be replaced by SPL_DRIVERS_MISC.
Hi folks,
I was creating a new imx6 board with an SPL and without enabling the "driver model for SPL" to keep a pretty simple SPL.
Then I wanted to enable the secure boot, and so the IMX_HAB option, which needs at compile time the "fuse_read" function.
This function is provided by the "mxc_ocotp" driver (in the misc section). This driver is totally not "driver model" oriented. It can be enabled for regular builds and SPL builds using the (SPL_)MXC_OCOTP option.
For the regular build, MXC_OCOTP does not have any dependency (except for the arch dependency), so no DM dependency here. But for the SPL build, the SPL_MXC_OCOTP needs the SPL_MISC option which is directly linked to the SPL_DM option.
I think this is just a typo and this should be only dependent on the "support of misc drivers in the SPL" so the SPL_DRIVERS_MISC option.
Am I right ? If someone confirms this point, I will propose a patch.
Best regards, Jean-Marie
