Build error occurs when CONFIG_EFI_SECURE_BOOT or CONFIG_EFI_CAPSULE_AUTHENTICATE is enabled, because hash-checksum.c is not compiled.
Since hash_calculate() implemented in hash-checksum.c can be commonly used aside from FIT image signature verification, this commit itroduces HASH_CALCULATE option to decide if hash-checksum.c shall be compiled.
Signed-off-by: Masahisa Kojima masahisa.kojima@linaro.org ---
Changes in v7: - newly introduce HASH_CALCULATE option
Changes in v6: - update lib/Makefile to compile hash-checksum.c, instead of selecting FIT_SIGNATURE in secure boot and capsule authentication.
Changes in v5: - Missing option for EFI_TCG2_PROTOROL already added in different commit. This commit adds FIT_SIGNATURE only.
Changes in v4: - newly added in this patch series, due to rebasing the base code.
