imx7: hab_arch: Provide a hab_arch.h file
In order to enable compile time differences in HAB interaction, we should split out the definition of the base address of the HAB API. Some version of the i.MX series have different offsets from the BootROM base for the HAB callback table. This patch defines the header into which we will define the i.MX7 specific offset. The offset of the i.MX7 function-callback table is simultaneously defined. Once done, we can latch a set of common function pointer locations from the offset given here and if necessary change the offset for different processors without any other code-change. For now all we support is i.MX7 so the only offset being defined is that for the i.MX7. Signed-off-by: Bryan O'Donoghue <bryan.odonoghue@linaro.org> Reviewed-by: Ryan Harkin <ryan.harkin@linaro.org>
