makefile: add support for building on macOS

2020-02-06T10:12:47Z

On macOS the readlink command does not include a -f flag. Instead default to using GNU readlink (which is often installed as greadlink). Signed-off-by: Alex Richardson Signed-off-by: Anup Patel

build: Use -ffreestanding

2020-01-08T03:40:24Z

this is a stand-alone/baremetal application, therefore demanding -ffreestanding would help it compile with hosted toolchains e.g. ( linux toolchains ), it also ensures that it won't be using platform optimizations like inlining mem* str* functions which gcc might decide especially with wrapper string functions in opensbi code Signed-off-by: Khem Raj Reviewed-by: Anup Patel

Makefile: Minor fix in OPENSBI_VERSION_GIT

2019-10-02T11:33:54Z

Currently, if someone has forked OpenSBI repo quite sometime back and this fork is not having updated tags from upstream riscv/opensbi repo then "git describe" command can fail. To tackle this, we redirect error output of "git describe" to /dev/null. Signed-off-by: Anup Patel Reviewed-by: Bin Meng

Include `git describe` in OpenSBI

2019-08-19T05:28:21Z

OpenSBI includes a version, but that is only updated when tagged. For users that are using the git releases we instead end up with an ambiguous version number, which makes it hard to figure out what everyone is using. This patch checks for a git directory and prints out the result of `git describe`, which is a mix of pretty and unambiguous.

include: Add version info to struct sbi_platform

2019-06-29T13:56:26Z

Add version control of sbi_platform structure - Add opensbi_version, this gives information of opensbi revision on which the sbi_platform table was created. - Add platform_version field in sbi_platform structure for platform level version control. Signed-off-by: Abner Chang Acked-by: Anup Patel

platform: Move platform common to lib/utils.

2019-06-19T04:18:56Z

Currently, platform/common contains platform/non-platform specific common minimal drivers and libraries. This is helpful is all platforms are built within opensbi framework. Move them to lib/utils so that any external platform code also can reuse the minimalistic drivers or other common libraries. This patch doesn't introduce any functional changes.

Makefile: explicitly disable PIE

2019-04-30T03:51:47Z

The various available RISC-V toolchains differ in their default configuration regarding PIE, e.g. the buildroot RISC-V toolchain has PIE disabled by default while the Debian toolchain has it enabled by default. OpenSBI currently doesn't support being built with PIE enabled, therefore disable it explicitly by passing "-fno-pie -no-pie" in CFLAGS. Signed-off-by: Karsten Merker Acked-by: Anup Patel

TOP: Allow building platform out-of-tree

2019-04-09T03:44:09Z

This patch extends our current build-system for building platform sources which are not part of OpenSBI sources. For example: Let's say we have out-of-tree ABC platform sources. We place these sources under /ABC directory along with its config.mk and objects.mk. To build out-of-tree ABC platform from OpenSBI directory: $ make PLATFORM_DIR=/ABC OR $ make PLATFORM_DIR= PLATFORM=ABC To build out-of-tree ABC platform from /ABC directory: $ make PLATFORM_DIR=/ABC -C OR $ make PLATFORM_DIR= PLATFORM=ABC -C Signed-off-by: Anup Patel Reviewed-by: Alistair Francis
