2015-11-11arm/arm64: Generalize bootblock C entry pointJulius Werner
When we first added ARM support to coreboot, it was clear that the bootblock would need to do vastly different tasks than on x86, so we moved its main logic under arch/. Now that we have several more architectures, it turns out (as with so many things lately) that x86 is really the odd one out, and all the others are trying to do pretty much the same thing. This has already caused maintenance issues as the ARM32 bootblock developed and less-mature architectures were left behind with old cruft. This patch tries to address that problem by centralizing that logic under lib/ for use by all architectures/SoCs that don't explicitly opt-out (with the slightly adapted existing BOOTBLOCK_CUSTOM option). This works great out of the box for ARM32 and ARM64. It could probably be easily applied to MIPS and RISCV as well, but I don't have any of those boards to test so I'll mark them as BOOTBLOCK_CUSTOM for now and leave that for later cleanup. BRANCH=None BUG=None TEST=Built Jerry and Falco, booted Oak.

2015-08-28arm64: xcompile: Add support for A53 erratum 843419Julius Werner
This patch adds support to enable a linker workaround to a hardware erratum on some early Cortex-A53 revisions. Since the linker option was added very recently, we use xcompile to test whether the toolchain supports it first. It is also guarded by a Kconfig since only a few ARM64 SoCs will need this and it incurs a performance penalty. BRANCH=none BUG=none TEST=Turned it on or off for Smaug and confirmed that it (dis)appeared in verbose make output accordingly.

2015-05-19arm64: Reorganize payload entry code and related KconfigsJulius Werner
Rename Kconfig options for secmon and spintable to be prefixed with ARM64_ instead of ARCH_, which seems to be the standard throughout the rest of coreboot (e.g. ARM_LPAE or X86_BOOTBLOCK_SIMPLE). I think this provides a clearer separation between generic options that are selected by the architecture (e.g. a hypothetical ARCH_HAS_FEATURE_X similar to some of the MAINBOARD_HAS_... we have) and options that only make sense in the context of a single architecture.

2015-04-02Clean up architecture-specific KconfigsJulius Werner
It's an unfortunate side effect of our different-archs-per-stage mechanism that all src/arch/*/Kconfig files are always parsed with no if blocks to exclude them if they're not relevant. This makes it very easy to accidentally rely on a Kconfig default set by a totally different and not applying architecture. This patch moves a few Kconfigs from ARM and X86 that leaked out like this into a common Kconfig file for clarity. It also gives ARM64 its own BOOTBLOCK_CUSTOM mechanism so that it doesn't leech off the ARM one (currently not used by any board). In the future, we should maybe prefix all options in the arch/*/Kconfig files with the architecture name (such as X86_BOOTBLOCK_NORMAL and ARM_LPAE are already doing), to make it more apparent when they are used in the wrong place.

This reverts the revert commit 5780d6f3876723b94fbe3653c9d87dad6330862e and fixes the build issue that cuased it to be reverted. Verstage will host vboot2 for firmware verification. It's a stage in the sense that it has its own set of toolchains, compiler flags, and includes. This allows us to easily add object files as needed. But it's directly linked to bootblock. This allows us to avoid code duplication for stage loading and jumping (e.g. cbfs driver) for the boards where bootblock has to run in a different architecture (e.g. Tegra124). To avoid name space conflict, verstage symbols are prefixed with verstage_. TEST=Built with VBOOT2_VERIFY_FIRMWARE on/off. Booted Nyan Blaze.
