2019-05-29Makefile.inc: Extend version string for timeless buildsNico Huber
With the version string "TIMELESS", binaries are slightly smaller than for a regular build. This may lead to false positive build tests if the space is limited (e.g. bootblock). So let's make the string a little longer.

2019-05-07Revert "Makefile.inc: Enable -Wtype-limits"Patrick Georgi
This reverts commit c4ab50cdde4bfd01ec7509012b105c88bcf4c953. Reason for revert: vboot recently was changed so that -Wtype-limits fails, and that was just brought upstream. Since vboot internals are more likely to be used elsewhere while -Wtype-limits is less critical, revert this until vboot is resolved, then bring -Wtype-limits back again.

2019-05-06Makefile.inc: Enable -Wtype-limitsJulius Werner
This patch enables -Wtype-limits for the whole repository, which disallows checking for a condition that must be always true or always false based on type width (e.g. checking whether an unsigned variable is negative or whether a 32-bit integer is larger than 4G). This helps avoid easy to make and hard to find (because they often only affect error paths) mistakes like size_t size = fmap_read_area(...); if (size < 0) die("If only the compiler could've told me to use ssize_t instead"); Change-Id: I19edabfd092d09dad720e3fc47b44838163bfe25 Signed-off-by: Julius Werner <jwerner@chromium.org> Reviewed-on: https://review.coreboot.org/c/coreboot/+/32536 Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Furquan Shaikh <furquan@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>

2019-01-10Untangle CBFS microcode updatesNico Huber
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. You may use it at your leisure.

GNU make is too smart (or too stupid?) for empty recipes. In the case of empty recipes, GNU make doesn't consider the target as updated even if its prerequisites are. So if we told make to rebuild `build/romstage/ lib/cbfs.o` for instance, and the FMAP changed, it rerun the fmaptool recipe (as a prerequisite) but only considered `cbfs.o` to be updated by chance. Just not leaving the recipes empty seems to help here. I seeemed to remember that it wasn't that easy, but it fixes the issue for me...

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.

2018-05-22Makefile.inc: Export CCACHE_EXTRAFILES and add __BUILD_DIR__ definitionJulius Werner
This patch adds the CCACHE_EXTRAFILES variable to the list of exported environment variables, which can be useful as a target-specific variable to make ccache aware of extra dependencies that it cannot figure out on its own. It also adds a CPPFLAGS parameter to define the __BUILD_DIR__ constant for the preprocessor so that the current output build directory can be referenced in C code if necessary.

2018-05-22Makefile.inc: Add separate bootblock.raw.elf with allocatable BSSJulius Werner
This patch moves the objcopy invocation that changes the bootblock's section flags to make sure .data and .bss are preserved in the binary image from the generation of bootblock.raw.bin into a separate bootblock.raw.elf file. Some SoCs (like SDM845) like to have an ELF rather than a raw binary as input to their masked ROM wrapper generation script. Also move those objcopy flags out into a variable because I'll need them again in a later patch.

2018-01-23util/gitconfig: Use `make` in git hooksAlex Thiessen
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.
