ARM: EXYNOS: Add support for Exynos secure firmware
Some Exynos-based boards contain secure firmware and must use firmware
operations to set up some hardware.
This patch adds firmware operations for Exynos secure firmware and a way
for board code and device tree to specify that they must be used.
Example of use:
In board code:
...MACHINE_START(...)
/* ... */
.init_early = exynos_firmware_init,
/* ... */
MACHINE_END
In device tree:
/ {
/* ... */
firmware@0203F000 {
compatible = "samsung,secure-firmware";
reg = <0x0203F000 0x1000>;
};
/* ... */
};
