include: Add separate header for OpenSBI version

2019-01-25T19:05:49Z

Currently, the OpenSBI version is in top-level Makefile so firmware linking to OpenSBI static library have no-way to know OpenSBI version. This patch moves OpenSBI version from top-level Makefile to sbi/sbi_version.h header which provides OPENSBI_VERSION_MAJOR and OPENSBI_VERSION_MINOR defines. NOTE: the SBI spec (or SBI ecall interface) version is different. The SBI spec version is provided by functions sbi_ecall_version_major() and sbi_ecall_version_minor(). Signed-off-by: Anup Patel

all: Update copyright header in all files

2019-01-24T08:37:47Z

Makefile: Don't install generic headers under /platform

2019-01-22T06:10:15Z

We don't need to install generic headers separately for every platforn under /platform. It is unnecessary duplication of files hence updating install_libplatsbi in top-level makefile. Signed-off-by: Anup Patel

docs: Add OpenSBI version to doxygen.cfg

2019-01-22T06:10:15Z

The PDF document generated by doxygen should have OpenSBI version hence this patch adds OpenSBI version to doxygen.cfg. Signed-off-by: Anup Patel

Makefile: Improve readability

2019-01-21T04:28:33Z

Repeating "ifdef CROSS_COMPILE" multiple times does not help with readability. Simplify by grouping compilation command setup under a single ifdef statement. Signed-off-by: Damien Le Moal

Makefile: Add support for device tree compilation

2019-01-21T04:28:33Z

Add rules to compile dts files into dtb files using the device tree compiler (dtc). A platform can specify the DTS file to compile using the platform-dtb-y variable. The flattened device tree binary file to be used for building the final polatform firmware can be specified using the new FW_PAYLOAD_FDT firmware configuration option to point to the automatically compiled FDT file. Using the existing FW_PAYLOAD_FDT_PATH configuration option is still possible and will take precedence over the FW_PAYLOAD_FDT definition. Signed-off-by: Damien Le Moal

platform: Include libfdt & libc.

Makefile: Add make targets to build and install documentation

2019-01-16T05:55:25Z

This patch extends top-level makefile to build and install documentation. The 'docs' make target is for building the documentation PDF whereas 'install_docs' make target is for installing the documentation PDF. Signed-off-by: Anup Patel

Makefile: Use '=' instead of '?=' for make variables

2019-01-05T11:10:22Z

The '?=' will not assign value if the target make variable is overriden via command-line or is set in environment variable. On other hand, '=' will not assign value only if variable is overriden via command-line parameter. It is quite common to have CC, AS, CPP, LD, etc to be set as environment variables pointing to native compiler and binutils. If '-rR' option is not set in MAKEFLAGS then this results in compile error because '?=' will use the native compiler and binutils. If '-rR' option is set in MAKEFLAGS then this again results in compile error because CC, AS, CPP, etc are set to empty strings which causes '?=' to use empty string as compiler and binutils. To handle this, we use '?=' only when CROSS_COMPILE is not defined and we use '=' when CROSS_COMPILE is defined. Signed-off-by: Anup Patel

Makefile: Force GCC to preprocess the linker file

2019-01-04T02:50:50Z

To avoid this message (and subsequent errors): warning: linker input file unused because linking not done force GCC to treat the linker script preprocessing as a C file. Signed-off-by: Alistair Francis
