imx: imx_snvs: Define a SNVS header and memory map
This commit defines two things.
- The basic SNVS memory map. At the moment that is total overkill for the
permission bits we need to set inside the SNVS but, for the sake of
completeness define the whole SNVS area as a struct.
- The bits of the HPCOMR register
A permission fix will need to be applied to the SNVS block prior to
switching on TrustZone. All we need to do is waggle a bit in the HPCOMR
register. To do that waggle we first need to define the bits of the
HPCOMR register.
- A imx_snvs_init() function definition
Declare the snvs_init() function so that it can be called from our
platform setup code.
