2018-02-26src/arch/x86/smbios.c: Fix type 17 part numberRichard Spiegel
Some DIMMs have invalid strings when it comes to device part number (bytes 0x149-0x15c). From DDR4 SPD specs it should be ASCIIZ with unused space filled with white spaces (ASCII 0x20). Byte 20 should be 0 (ASCIIZ), all others should be ASCII. Create a test that detects invalid strings and replace invalid characters with *. If a replacement was made the output string then must be <Invalid (replaced string)>. BUG=b:73122207 TEST=Build, boot and record serial output for kahlee while injecting different strings to dmi17->PartNumber. Use code to examine SMBIOS, while testing different valid and invalid strings. Remove string injection before committing.

2018-02-02arm64: Pass COREBOOT flag to ARM TF, always enable loggingJulius Werner
This patch changes the way coreboot builds ARM TF to pass the new COREBOOT flag introduced with the following pull request: https://github.com/ARM-software/arm-trusted-firmware/pull/1193 Since the new coreboot support code supports the CBMEM console, we need to always enable LOG_LEVEL INFO. Supporting platforms will parse the coreboot table to conditionally enable the serial console only if it was enabled in coreboot as well. Also remove explicit cache flushes of some BL31 parameters. Turns out we never really needed these because we already flush the whole cache when disabling the MMU, and we were already not doing it for most parameters.

2017-10-29arch/x86: Restore forwarding table on resume for non EARLY_EBDA_INITFurquan Shaikh
In commit c06a3f72 (arch/x86: initialize EBDA in S3 and S0/S5 path), BDA and EBDA are wiped in the resume path. It results in coreboot forwarding table address being wiped out since it is stored in the BDA. This issue was resolved for platforms using EARLY_EBDA_INIT in commit f46a9a0d (arch/x86: restore forwarding table on resume for EARLY_EBDA_INIT). However platforms that do not use EARLY_EBDA_INIT still run into the same issue and hence cbmem does not work on resume. This change fixes the issue by using the stash/restore of forwarding table address for all platforms using BDA. BUG=b:68412690 TEST=Verified that cbmem works on S3 resume for coral.

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.)

2017-03-28Remove 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.

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().
