* make: Fix ec+cryptoc's no-change remake behaviorCraig Hesling2020-12-291-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the cryptoc (specifically libcryptoc.a) target is marked as always PHONY. That means that any project that depends on cryptoc will always rebuild ec.bin on make invocations. For example, running make for bloonchipper will show the following build step repeatedly, even though nothing in libcryptoc changed: $ make BOARD=bloonchipper MAKE cryptoc/libcryptoc.a LD RW/ec.RW.elf NM RW/ec.RW.smap OBJCOPY RW/ec.RW.flat LD RO/ec.RO.elf NM RO/ec.RO.smap OBJCOPY RO/ec.RO.flat SIGN RW/ec.RW.flat.sig CAT ec.obj OBJCOPY ec.bin SIGN ec.bin EXTR_RW ec.bin MV ec.bin *** 80068 bytes in flash ... on bloonchipper RO **** *** 477576 bytes in flash ... on bloonchipper RW **** This fix brings the dirty/clean state of cryptoc into the main EC make process, so that it can assess if libcryptoc.a (and later ec.bin) actually need to be remade. We do something similar for the ec version header file that is generated by the build system itself. https://github.com/coreboot/chrome-ec/blob/ef6a915de0a2b65c18c03074b66717d597675162/Makefile.rules#L593,L595 This change was only possible with the fix to cryptoc's Makefile crrev.com/c/2091999 . With this change, projects that depend on cryptoc will not always force an unnecessary recompilation, so the above bloonchipper example look like the following after the initial build: $ make BOARD=bloonchipper *** 80068 bytes in flash ... on bloonchipper RO **** *** 477576 bytes in flash ... on bloonchipper RW **** BRANCH=none BUG=none TEST=rm -rf build make BOARD=bloonchipper make BOARD=bloonchipper # Check that nothing needed to be made TEST=rm -rf build make buildall -j7 make BOARD=bloonchipper # Check that nothing needed to be made Cq-Depend: chromium:2091999 Change-Id: I3f4d88c9d673f2dc7e29122699521f0f52f7572d Signed-off-by: Craig Hesling <hesling@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/ec/+/2593881 Reviewed-by: Vadim Bendebury <vbendeb@chromium.org>

The trace for this goes as follows: Setting CORE_CORTEX_M sets GHASH_ASM, which later on sets GHASH. Certain sections of code that use this static const are disabled if GHASH is not set. Thus, no uses of this static const. This issue arose when attempting to add the fpsensor task to host_command_fuzz, but is actually present(and unreported) in the fpsensor unit test. The presence of this unreported issue in the host-fpsensor build target was discovered by manually invoking cpp for aes-gcm.c and checking that the static const existed, but was not references.

* aes: Adapt AES code to build for ECNicolas Boichat2018-09-203-187/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Update header, C code, and tweak the assembly for ARMv7-M. Rename aes_now_* functions to AES_* to avoid the need for a separate wrapper. Also add a test with FIPS-197 test vectors, and speed test.
