2017-07-13arch/x86/assembly_entry: Align stack for car_stage_entryMarshall Dawson
At process _start, the stack is expected to be aligned to a 16-byte boundary. Upon entry to any function the stack frame must have the end of any arguments also aligned. In other words the value of %esp+4 or %rsp+8 is always a multiple of 16 (1). Align the stack down and change the method for executing car_stage_entry from jmp to call which should preserve proper alignment regardless of a 32- or 64-bit build. Although 4-byte alignment is the minimum requirement for i386, some AMD platforms use SSE instructions which expect 16-byte. 1) http://wiki.osdev.org/System_V_ABI See "Initial Stack and Register State" and "The Stack Frame" in the supplements.

2017-05-30arch: Unify basic cache clearing APIJulius Werner
Caching is a very architecture-specific thing, but most architectures have a cache in general. Therefore it can be useful to have a generic architecture-independent API to perform simple cache management tasks from common code. We have already standardized on the dcache_clean/invalidate naming scheme that originally comes from ARM in libpayload, so let's just do the same for coreboot. Unlike libpayload, there are other things than just DMA coherency we may want to achieve with those functions, so actually implement them for real even on architectures with cache-snooping DMA like x86. (In the future, we may find applications like this in libpayload as well and should probably rethink the API there... maybe move the current functionality to a separate dma_map/unmap API instead. But that's beyond scope of this patch.)

2017-05-30arm64: Align cache maintenance code with libpayload and ARM32Julius Werner
coreboot and libpayload currently use completely different code to perform a full cache flush on ARM64, with even different function names. The libpayload code is closely inspired by the ARM32 version, so for the sake of overall consistency let's sync coreboot to that. Also align a few other cache management details to work the same way as the corresponding ARM32 parts (such as only flushing but not invalidating the data cache after loading a new stage, which may have a small performance benefit).

Currently only 256 bytes can be written at a time using the acpigen_write_return_byte_buffer or acpigen_write_byte_buffer API's and there can be cases where the buffer size can exceed this, hence increase the number of bytes that can be written.

2017-03-28Remove libverstage as separate library and source file classJulius Werner
In builds without CONFIG_VBOOT_SEPARATE_VERSTAGE, verstage files are linked directly into the bootblock or the romstage. However, they're still compiled with a separate "libverstage" source file class, linked into an intermediate library and then linked into the final destination stage. There is no obvious benefit to doing it this way and it's unclear why it was chosen in the first place... there are, however, obvious disadvantages: it can result in code that is used by both libverstage and the host stage to occur twice in the output binary. It also means that libverstage files have their separate compiler flags that are not necessarily aligned with the host stage, which can lead to weird effects like <rules.h> macros not being set the way you would expect. In fact, VBOOT_STARTS_IN_ROMSTAGE configurations are currently broken on x86 because their libverstage code that gets compiled into the romstage sets ENV_VERSTAGE, but CAR migration code expects all ENV_VERSTAGE code to run pre-migration. This patch resolves these problems by removing the separate library. There is no more difference between the 'verstage' and 'libverstage' classes, and the source files added to them are just treated the same way a bootblock or romstage source files in configurations where the verstage is linked into either of these respective stages (allowing for the normal object code deduplication and causing those files to be compiled with the same flags as the host stage's files). Tested this whole series by booting a Kevin, an Elm (both with and without SEPARATE_VERSTAGE) and a Falco in normal and recovery mode.

2017-03-28vboot: Move remaining features out of vendorcode/google/chromeosJulius Werner
This patch attempts to finish the separation between CONFIG_VBOOT and CONFIG_CHROMEOS by moving the remaining options and code (including image generation code for things like FWID and GBB flags, which are intrinsic to vboot itself) from src/vendorcode/google/chromeos to src/vboot. Also taking this opportunity to namespace all VBOOT Kconfig options, and clean up menuconfig visibility for them (i.e. some options were visible even though they were tied to the hardware while others were invisible even though it might make sense to change them).

2017-03-28vboot: Remove CHIPSET_PROVIDES_VERSTAGE_MAIN_SYMBOL Kconfig optionJulius Werner
CHIPSET_PROVIDES_VERSTAGE_MAIN_SYMBOL allows the SoC directory to provide its own main() symbol that can execute code before the generic verstage code runs. We have now established in other places (e.g. T210 ramstage) a sort of convention that SoCs which need to run code in any stage before main() should just override stage_entry() instead. This patch aligns the verstage with that model and gets rid of the extra Kconfig option. This also removes the need for aliasing between main() and verstage(). Like other stages the main verstage code is now just in main() and can be called from stage_entry().

2017-03-28arm64: Fix verstage to use proper assembly versions of mem*()Julius Werner
Due to an unfortunate race between adding verstage support and reverting an earlier hack that disabled the optimized assembly versions of memcpy(), memmove() and memset() on ARM64, it seems that we never enabled the optimized code for the verstage. This should be fixed so that all stages use the same architecture support code.

2017-03-19ramstage: Align stack to 16 bytesKyösti Mälkki
Some SSE instructions could take 128bit memory operands from stack. AGESA vendorcode was always built with SSE enabled, but until now stack alignment was not known to cause major issues. Seems like GCC-6.3 more likely emits instructions that depend on the 16 byte alignment of stack.
