Makefile: Rename compile_ld() to compile_elf()

2019-02-22T05:58:41Z

The compile_ld() is actually used to create ELF files so the name is misleading hence this patch renames it to compile_elf(). We also rename LDFLAGS to ELFFLAGS because these will be used for ELF creation only. Signed-off-by: Anup Patel

Makefile: Use sed instead of awk to parse OpenSBI version

2019-02-19T08:17:18Z

This patch replaces use of awk with sed in top-level makefile to parse OpenSBI version from include/sbi/sbi_version.h. Signed-off-by: Anup Patel

Makefile: Fix error evaluating OPENSBI_CC_XLEN

2019-02-19T08:17:18Z

We get following error evaluating OPENSBI_CC_XLEN on Ubuntu-18.04: /bin/sh: 1: Bad substitution This patch fixes above error by using "awk" in string assigned to OPENSBI_CC_XLEN and it also moves "Setup compilation commands" before OPENSBI_CC_XLEN. Signed-off-by: Anup Patel

Makefile: Fix the assignment of OPENSBI_CC_XLEN

2019-02-17T10:51:18Z

Previously OPENSBI_CC_XLEN was not being correctly assigned either 32 or 64. It also was not assigned before config.mk was parsed. Ensure that it will always be assigned. Signed-off-by: Alistair Francis

Makefile: Add 'make run' command for platform specific run

2019-02-15T10:24:44Z

Makes for easy and quick build-run one-stop command. For now only added for qemu targets. It can be added for any platform having simulator/emulator (such as QEMU). Signed-off-by: Olof Johansson Signed-off-by: Anup Patel

Makefile: Make sure ld is always aware of the target abi/emulation

2019-02-15T03:25:45Z

On Makefile merge_objs calls ld without providing any hints on the target so on a multilib toolchain for example it will always pick the default one (elf64-littleriscv) which will then result a failure when compiling on RV32 since the objects will be 32bits and the target will be 64bits. The same happens on compile_ld that calls gcc without CFLAGS so it doesn't get mabi/march. With this patch OpenSBI compiles on RV32 (PLATFORM_RISCV_XLEN=32), I tested fw_jump.elf on qemu (but it doesn't boot the kernel yet -bbl also doesn't boot the kernel so it may be something else).

Makefile: Set ABI, ISA and Code Model in top-level make

2019-02-12T10:25:15Z

This patch introduces following optional PLATFORM options: PLATFORM_RISCV_XLEN -> RISC-V register width PLATFORM_RISCV_ABI -> RISC-V GCC ABI PLATFORM_RISCV_ISA -> RISC-V GCC ISA string PLATFORM_RISCV_CODE_MODEL -> RISC-V GCC Code Model If the above options are not provided by platform config.mk or by command-line parameters then: 1. PLATFORM_RISCV_XLEN will be determined using toolchain capability 2. PLATFORM_RISCV_ABI, PLATFORM_RISCV_ISA, and PLATFORM_RISCV_CODE_MODEL is set to value best suited for generic libsbi.a As a result of these optional PLATFORM options, the platform-cflags-y and platform-asflags-y is further simplified for platform config.mk.

Makefile: Ensure lgcc is included

2019-02-08T03:48:46Z

This fixes errors like this: undefined reference to `__umoddi3' when buildilng for 32-bit systems Signed-off-by: Alistair Francis

platform/qemu/virt: Dynamically calculate xlen

2019-02-08T03:48:46Z

The QEMU virt machine can be either 32 or 66 bit. Don't hard code the CPU bit length and instead let the compiler determine it. Signed-off-by: Alistair Francis

Makefile: don't disable built-in variables
