ARM: disable KCOV for trusted foundations code

2018-07-04T00:32:19Z

The ARM trusted foundations code is currently broken in linux-next when CONFIG_KCOV_INSTRUMENT_ALL is set: /tmp/ccHdQsCI.s: Assembler messages: /tmp/ccHdQsCI.s:37: Error: .err encountered /tmp/ccHdQsCI.s:38: Error: .err encountered /tmp/ccHdQsCI.s:39: Error: .err encountered scripts/Makefile.build:311: recipe for target 'arch/arm/firmware/trusted_foundations.o' failed I could not find a function attribute that lets me disable -fsanitize-coverage=trace-pc for just one function, so this turns it off for the entire file instead.

ARM: add basic support for Trusted Foundations

2013-12-13T19:50:30Z

Trusted Foundations is a TrustZone-based secure monitor for ARM that can be invoked using the same SMC-based API on supported platforms. This patch adds initial basic support for Trusted Foundations using the ARM firmware API. Current features are limited to the ability to boot secondary processors. Note: The API followed by Trusted Foundations does *not* follow the SMC calling conventions. It has nothing to do with PSCI neither and is only relevant to devices that use Trusted Foundations (like most Tegra-based retail devices).
