2019-02-18lib: Improve delivery of SBI_IPI_EVENT_HALTNick Kossifidis1-13/+34
When sbi_ipi_send_many gets called with the current hartid included on pmask (or when pmask is NULL), and we send a HALT event, since the for loop works sequentially over all hartids on the mask, we may send a HALT event to the current hart before the loop finishes. So we will halt the current hart before it can deliver a HALT IPI to the rest and some harts will remain active. Make sure we send an IPI to the current hart after we've finished with everybody else.

2019-02-18platform: qemu-virt: Implement system shutdownNick Kossifidis1-1/+9
In order for QEMU to be compatible with Spike, it implements a simple protocol used for reporting back the simulation's status, through the memory-mapped "test finisher" device. We use that protocol to make QEMU exit on system shutdown. Signed-off-by: Nick Kossifidis <mick@ics.forth.gr>
2019-02-18lib: Send IPI for all harts to hang on system shutdownNick Kossifidis1-0/+8
In case the platform specific method for shutting down the system fails (or is not implemented), at least make sure that all harts hang instead of just the current hart. Signed-off-by: Nick Kossifidis <mick@ics.forth.gr>
2019-02-17Makefile: Fix the assignment of OPENSBI_CC_XLENAlistair Francis1-3/+3
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 <alistair.francis@wdc.com>

2019-02-15Makefile: Add 'make run' command for platform specific runOlof Johansson4-6/+35
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 <olof@lixom.net> Signed-off-by: Anup Patel <anup.patel@wdc.com>

2019-02-15firmware: Ensure the payloads are 4 bit allignedAlistair Francis1-4/+5
We expect the payloads to be 4 bit alligned as we later AND them with ~0xf. As most of the addresses are manually specified we don't really need this, but better to be over cautious. Signed-off-by: Alistair Francis <alistair.francis@wdc.com>
2019-02-15Makefile: Make sure ld is always aware of the target abi/emulationNick Kossifidis1-1/+3
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).

2019-02-12Makefile: Set ABI, ISA and Code Model in top-level makeAnup Patel6-25/+46
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.

2019-02-12platform: qemu: Set FW_JUMP_ADDR and FW_PAYLOAD_OFFSET as-per XLENAnup Patel2-6/+28
The current 4MB aligned FW_JUMP_ADDR and FW_PAYLOAD_OFFSET breaks U-Boot on QEMU virt and sifive_u machines. Instead of using 4MB aligned for both 32bit and 64bit systems, we use different values based compiler XLEN. Another advantage of this approach will be that our fw_payload.bin will smaller for 64bit systems. Signed-off-by: Anup Patel <anup.patel@wdc.com>

Currently, only hart 1 is enabled for fu540 platform to support U-boot. Introduce a compile time FU540_ENABLED_HART_MASK option so that specific harts can be selected for booting.

2019-01-25include: Add separate header for OpenSBI versionAnup Patel3-9/+24
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().
