Andre Przywara	ac17e52c72	refactor(cpufeat): enable FEAT_RNG for FEAT_STATE_CHECKED ... At the moment we only support for FEAT_RNG to be either unconditionally compiled in, or to be not supported at all. Add support for runtime detection (FEAT_RNG=2), by splitting is_armv8_5_rng_present() into an ID register reading function and a second function to report the support status. That function considers both build time settings and runtime information (if needed), and is used before we access the RNDRRS system register. Change the QEMU platform default to the now supported dynamic option (=2), so the right decision can be made by the code at runtime.

Tomas Pilar	83683ddd3d	plat/qemu: Use RNDR in stack protector ... When getting a stack protector canary value, check if cpu supports FEAT_RNG and use that. Fallback to old method of using a (hardcoded value ^ timer). Signed-off-by: Tomas Pilar <tomas@nuviainc.com> Change-Id: I8181acf8e31661d4cc82bc3a4078f8751909e725	2021-01-19 11:58:13 +00:00
Radoslaw Biernacki	301d27d998	qemu: introducing sub-platforms to qemu platform ... This commit change the plat/qemu directory structure into: `-- plat `-- qemu |-- common (files shared with all qemu subplatforms) |-- qemu (original qemu platform) |-- qemu_sbsa (new sqemu_sbsa platform) |-- subplat1 `-- subplat2 This opens the possibility of adding new qemu sub-platforms which reuse existing common platform code. The first platform which will leverage new structure will be SBSA platform.
