2019-11-04cpu/qemu-x86: Add x86_64 bootblock supportPatrick Rudolph
Add support for x86_64 bootblock on qemu. Introduce a new approach to long mode support. The previous patch set generated page tables at runtime and placed them in heap. The new approach places the page tables in memory mapped ROM. Introduce a new tool called pgtblgen that creates x86 long mode compatible page tables and writes those to a file. The file is included into the CBFS and placed at a predefined offset. Add assembly code to load the page tables, based on a Kconfig symbol and enter long in bootblock. The code can be easily ported to real hardware bootblock. Tested on qemu q35.

2019-06-11Rampayload: Able to build coreboot without ramstageSubrata Banik
This patch removes all possible dependencies in order to build platform with CONFIG_RAMPAYLOAD enable(without ramstage). A. Create coreboot separate stage kconfigs This patch creates seperate stage configs as below 1. HAVE_BOOTBLOCK 2. HAVE_VERSTAGE 3. HAVE_ROMSTAGE 4. HAVE_POSTCAR 5. HAVE_RAMSTAGE B. Also ensures below kconfigs are aligned with correct stage configs 1. COMPRESS_RAMSTAGE and RELOCATABLE_RAMSTAGE are now enable if CONFIG_HAVE_RAMSTAGE is selected. 2. COMPRESS_BOOTBLOCK will enable if CONFIG_HAVE_BOOTBLOCK is set 3. COMPRESS_PRERAM_STAGES will enable if CONFIG_HAVE_VERSTAGE || CONFIG_HAVE_ROMSTAGE is selected. C. Also fix compilation issue with !CONFIG_HAVE_RAMSTAGE On x86 platform: Case 1: ramstage do exist: CONFIG_HAVE_RAMSTAGE=1 >> rmodules_$(ARCH-ramstage-y) will evaluate as rmodules_x86_32 Case 2: ramstage doesn't exist: CONFIG_HAVE_RAMSTAGE=0 >> rmodules_$(ARCH-ramstage-y) will evaluate as rmodules_ This patch fixes Case 2 usecase where platform doesn't select CONFIG_HAVE_RAMSTAGE. Also add option to create sipi_vector.manual based on $(TARGET_STAGE) variable. $(TARGET_STAGE)=ramstage if user selects CONFIG_HAVE_RAMSTAGE $(TARGET_STAGE)=postcar if user selects CONFIG_RAMPAYLOAD Change-Id: I0f7e4174619016c5a54c28bedd52699df417a5b7 Signed-off-by: Subrata Banik <subrata.banik@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/33142 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Aaron Durbin <adurbin@chromium.org>

The option to specify a binary file name was added later for platforms that do not provide microcode updates in our blobs repository. Alas, it wasn't visible what platforms these are. And if you specified a file for a platform that already had one, they were all included together. Make it visible which platforms don't provide binaries with the new con- figs MICROCODE_BLOB_NOT_IN_BLOB_REPO, MICROCODE_BLOB_NOT_HOOKED_UP and MICROCODE_BLOB_UNDISCLOSED. Based on that we can decide if we want to include binaries by default or explicitly show that no files are inclu- ded (default to CPU_MICROCODE_CBFS_NONE). Also split CPU_MICROCODE_CBFS_GENERATE into the more explicit CPU_MICROCODE_CBFS_DEFAULT_BINS and CPU_MICROCODE_CBFS_EXTERNAL_BINS. And clean up the visibility of options: Don't show CBFS related options on platforms that don't support it and don't show external file options if the platform uses special rules for multiple files (CPU_MICROCODE_ MULTIPLE_FILES).

Use the `git-format' tool to sanitise coreboot commits such that they conform to coreboot's coding style. This fancy piece of machinary allows one to have LibFormat from Clang to automatically check your commit conforms to coreboot's coding style, fix any issues automatically and provides you a diff you may review and apply at your convenience. N.B. When the `clang-format' binary is not found we issue a warning that the test was skipped and carry on as usual. Hence, this is strictly non-enforcing at this current time.

Fix this case, by making this rule depend on $(objutil)/kconfig/conf. The same fix is also precautiously applied to the rule for $(KCONFIG_AUTOHEADER) in Makefile.

2018-08-20Makefile.inc: Ensure update of build.hNico Huber
There were so many pitfalls that I wrote my own version of this even- tually. This version is inspired by the procedure of Alex Thiessen[1]. Instead of generating a `build.h` on demand, we always generate a tem- porary version that, if it differs from the current one, is added as a dependency. As we use .SECONDEXPANSION on the prerequisites, special care is taken that we won't generate the file twice. As it would be too late to add the dependency if we'd run `genbuild_h.sh` inside a recipe, we have to run it through the `$(shell)` function. But that brings us to the next issue: The make variables used by `genbuild_h.sh` are not expor- ted to this shell like they would be in a recipe. So we export them manually. We could also make these variables explicit parameters of `genbuild_h.sh` instead. An alternative to always creating the temporary `build.h` would be to add a phony target as dependency instead, and finally calling `genbuild_h.sh` again in case we need an update. But, um, we create so many files anyway...

2018-05-22Introduce bootblock self-decompressionJulius Werner
Masked ROMs are the silent killers of boot speed on devices without memory-mapped SPI flash. They often contain awfully slow SPI drivers (presumably bit-banged) that take hundreds of milliseconds to load our bootblock, and every extra kilobyte of bootblock size has a hugely disproportionate impact on boot speed. The coreboot timestamps can never show that component, but it impacts our users all the same. This patch tries to alleviate that issue a bit by allowing us to compress the bootblock with LZ4, which can cut its size down to nearly half. Of course, masked ROMs usually don't come with decompression algorithms built in, so we need to introduce a little decompression stub that can decompress the rest of the bootblock. This is done by creating a new "decompressor" stage which runs before the bootblock, but includes the compressed bootblock code in its data section. It needs to be as small as possible to get a real benefit from this approach, which means no device drivers, no console output, no exception handling, etc. Besides the decompression algorithm itself we only include the timer driver so that we can measure the boot speed impact of decompression. On ARM and ARM64 systems, we also need to give SoC code a chance to initialize the MMU, since running decompression without MMU is prohibitively slow on these architectures. This feature is implemented for ARM and ARM64 architectures for now, although most of it is architecture-independent and it should be relatively simple to port to other platforms where a masked ROM loads the bootblock into SRAM. It is also supposed to be a clean starting point from which later optimizations can hopefully cut down the decompression stub size (currently ~4K on RK3399) a bit more. NOTE: Bootblock compression is not for everyone. Possible side effects include trying to run LZ4 on CPUs that come out of reset extremely underclocked or enabling this too early in SoC bring-up and getting frustrated trying to find issues in an undebuggable environment. Ask your SoC vendor if bootblock compression is right for you.

As the code was moved from the Makefile.inc to a separate file in commit 9ab8ae6a (util/gitconfig: Make gitconfig a bash script),`$(MAKE)` was replaced by `remake`, introducing dependency on this tool which is basically a `make` with debugging capabilities. Many developers don't have `remake` installed, leading to pre-commit hooks being not executed properly. Apparently this was an unintentional change. Furthermore, special treatment of `make` tool via the `%MAKE%` substitution performed during hooks' deployment is still desired. Use case is calling `remake gitconfig` to set `remake` as the `make` tool in the hooks. To accomplish this, add a parameter that is passed from the Makefile.inc to gitconfig.sh.

2017-06-04console/flashsconsole: Add spi flash console for debuggingYouness Alaoui
If CONSOLE_SPI_FLASH config is enabled, we write the cbmem messages to the 'CONSOLE' area in FMAP which allows us to grab the log when we read the flash. This is useful when you don't have usb debugging, and UART lines are hard to find. Since a failure to boot would require a hardware flasher anyways, we can get the log at the same time. This feature should only be used when no alternative is found and only when we can't boot the system, because excessive writes to the flash is not recommended. This has been tested on purism/librem13 v2 and librem 15 v3 which run Intel Skylake hardware. It has not been tested on other archs or with a driver other than the fast_spi.

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.
