Hi, There has already been multiple tentatives trying to add support for the Sama5d2 security module and in particular, access to its SRAM. After multiple discussions, I believe adding support in the sram driver/framework is probably the best because it allows exporting the SRAM to the kernel, to userspace and also to run code from it.
As the support for the sama5d2 securam is fairly small, I've included it directly in the mmio-sram driver.
