2019-11-25Kconfig: Drop the C_ENVIRONMENT_BOOTBLOCK symbolArthur Heymans
The romcc bootblock will be deprecated soon and most platforms use C_ENVIRONMENT_BOOTBLOCK already. This patch drops the CONFIG_C_ENVIRONMENT_BOOTBLOCK symbol and adds CONFIG_ROMCC_BOOTBLOCK where needed.

This solution is very generic and can in principle be implemented on all arch/soc. Instead trying to figure out which files can be removed from stages and which cbmem_top implementations need with preprocessor, rename all cbmem_top implementation to cbmem_top_romstage. Mechanisms set in place to pass on information from rom- to ram-stage will be placed in a followup commit.

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.

Commit 54229a7 (arm: Fix checkstack() to use correct stack size) didn't quite hit the mark. Due to the crazy way our Kconfig includes work, It accidentally set CONFIG_STACK_SIZE to 0 even on architectures that need it.

2015-04-14arm: Fix checkstack() to use correct stack sizeJulius Werner
checkstack() runs at the end of ramstage to warn about stack overflows, and it assumes that CONFIG_STACK_SIZE is always the size of the stack to check. This is only true for systems that bring up multiprocessing in ramstage and assign a separate stack for each core, like x86 and ARM64. Other architectures like ARM and MIPS (for now) don't touch secondary CPUs at all and currently don't look like they'll ever need to, so they generally stay on the same (SRAM-based) stack they have been on since their bootblock. This patch tries to model that difference by making these architectures explicitly set CONFIG_STACK_SIZE to zero, and using that as a cue to assume the whole (_estack - _stack) area in checkstack() instead. Also adds a BUG() to the stack overflow check, since that is currently just as non-fatal as the BIOS_ERR message (despite the incorrect "SYSTEM HALTED" output) but a little more easy to spot. Such a serious failure should not drown out in all the normal random pieces of lower case boot spam (also, I was intending to eventually have a look at assert() and BUG() to hopefully make them a little more useful/noticeable if I ever find the time for it). BRANCH=None BUG=None TEST=Booted Pinky, noticed it no longer complains about stack overflows. Built Falco, Ryu and Urara.

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.

2015-01-27CBMEM console: Fix and enhance pre-RAM supportKyösti Mälkki
Use the value of CONSOLE_PRERAM_BUFFER_SIZE to determine if we can do CBMEM console in bootblock and romstage. Kconfig forces it to zero if _BASE is unset or we cannot do CAR migration on x86. Add CBMEM console to bootblock, except for x86. Only one of bootblock and romstage clears the pre-RAM buffer. To start with empty console log on S3 wakeup, ramstage now clears previous contents of CBMEM buffer if there was no pre-RAM buffer. Unify Kconfig variable naming.

2014-09-08ARM: Generalize armv7 as arm.Gabe Black
There are ARM systems which are essentially heterogeneous multicores where some cores implement a different ARM architecture version than other cores. A specific example is the tegra124 which boots on an ARMv4 coprocessor while most code, including most of the firmware, runs on the main ARMv7 core. To support SOCs like this, the plan is to generalize the ARM architecture so that all versions are available, and an SOC/CPU can then select what architecture variant should be used for each component of the firmware; bootblock, romstage, and ramstage.
