2016-03-05arch/x86: Add common assembly code for stages that run in CARAndrey Petrov
This adds a few assembly lines that are generic enough to be shared between romstage and verstage that are ran in CAR. The GDT reload is bypassed and the stack is reloaded with the CAR stack defined in car.ld. The entry point for all those stages is car_stage_entry().

2016-02-10arch/arm64: Use correct SPSR.DAIF mask for BL31 and payloadJulius Werner
The PSTATE mask bits for Debug exceptions, external Aborts, Interrupts and Fast interrupts are usually best left unset: under normal circumstances none of those exceptions should occur in firmware, and if they do it's better to get a crash close to the code that caused it (rather than much later when the kernel first unmasks them). For this reason arm64_cpu_init unmasks them right after boot. However, the EL2 payload was still running with all mask bits set, which this patch fixes. BL31, on the other hand, explicitly wants to be entered with all masks set (see calling convention in docs/firmware-design.md), which we had previously not been doing. It doesn't seem to make a difference at the moment, but since it's explicitly specified we should probably comply. BRANCH=None BUG=None TEST=Booted Oak, confirmed with raw_read_daif() in payload that mask bits are now cleared.

2016-02-10arch/arm64: mmu: Spot check TTB memory attributesJulius Werner
On ARM64, the memory type for accessing page table descriptors during address translation is governed by the Translation Control Register (TCR). When the MMU code accesses the same descriptors to change page mappings, it uses the standard memory type rules (defined by the page table descriptor for the page that contains that table, or 'device' if the MMU is off). Accessing the same memory with different memory types can lead to all kinds of fun and hard to debug effects. In particular, if the TCR says "cacheable" and the page tables say "uncacheable", page table walks will pull stale entries into the cache and later mmu_config_range() calls will write directly to memory, bypassing those cache lines. This means the translations will not get updated even after a TLB flush, and later cache flushes/evictions may write the stale entries back to memory. Since page table configuration is currently always done from SoC code, we can't generally ensure that the TTB is always mapped as cacheable. We can however save developers of future SoCs a lot of headaches and time by spot checking the attributes when the MMU gets enabled, as this patch does. BRANCH=None BUG=None TEST=Booted Oak. Manually tested get_pte() with a few addresses.

2016-01-30arch/x86: Implement minimal bootblock for C_ENVIRONMENT_BOTOBLOCKAlexandru Gagniuc
Some newer x86 systems can boot from non-memory-mapped boot media (e.g. EMMC). The bootblock may be backed by small amounts of SRAM, or other memory, similar to how most ARM chipsets work. In such cases, we may not have enough code space for romstage very early on. This means that CAR setup and early boot media (e.g. SPI, EMMC) drivers need to be implemented within the limited amount memory of storage available. Since the reset vector has to be contained in this early code memory, the bootblock is the best place to implement loading of other stages. Implement a bootblock which does the minimal initialization, up to, and including switch to protected mode. This then transfers control to platform-specific code. No stack is needed, and control is transferred via a "jmp" such that no stack operations are involved.

2016-01-21arch/x86: Add files needed for C environment bootblock on x86Alexandru Gagniuc
This provides symbols needed by CBFS and FMAP APIs, and allows running run_romstage() in an x86 bootblock. Note that console-related files are not added in this patch, as they are not essential for the functinality on an x86 environment bootbock.

2016-01-21console: Simplify bootblock console Kconfig selection logicAlexandru Gagniuc
Instead of depending BOOTBLOCK_CONSOLE on a set of architectures, allow the arch or platform to specify whether it can provide a C environment. This simplifies the selection logic.

2016-01-21arch/x86/include: Rename bootblock_common to bootblock_romcc.hAlexandru Gagniuc
This header is only used for the bootblock compiled with ROMCC. As the follow-on patches introduce a bootblock which does not make use of ROMCC, rename this header to prevent confusion.

2016-01-19arch/x86/Makefile.inc: Add a comment to fix syntax highlightingMartin Roth
Trivial fix for syntax highlighting in editors. Some get confused by the double quote that doesn't have a close quote and stop highlighting at that point. This comment closes the quote and the paren pair so that they can recover.

2016-01-18arch/x86/Makefile.inc: Update symbol check macroMartin Roth
This was breaking the build on OS X, but also wasn't working correctly under linux anymore either. It wouldn't print the illegal symbols when it failed. - Split the generation of the offenders file from the actual check for offending symbols and just send all output to /dev/null. - Rewrite the check for offending symbols in a way that works with OS X. Tested by adding a global variable to romstage and verifying the failure is shown correctly. Verified that it works correctly with no illegal variables.

These were mostly written as part of the coreboot project, so get the standard coreboot license header. memmove.c came from the linux kernel, so also gets the standard coreboot v2 license header, but gets the added attribution that it was derived from the linux kernel.
