* riscv/boot: Fix possible memory leakAlistair Francis2019-10-281-7/+4
| | | | | | | | | | | | | Coverity (CID 1405786) thinks that there is a possible memory leak as we don't guarantee that the memory allocated from riscv_find_firmware() is freed. This is a false positive, but let's tidy up the code to fix the warning.

* riscv: Resolve full path of the given bios imageBin Meng2019-09-171-3/+3
| | | | | | | | | | At present when "-bios image" is supplied, we just use the straight path without searching for the configured data directories. Like "-bios default", we add the same logic so that "-L" actually works.

* riscv: Add a helper routine for finding firmwareBin Meng2019-09-171-7/+15
| | | | | | | | | This adds a helper routine for finding firmware. It is currently used only for "-bios default" case. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Alistair Francis <alistair.francis@wdc.com> Signed-off-by: Palmer Dabbelt <palmer@sifive.com>
* Include hw/boards.h a bit lessMarkus Armbruster2019-08-161-1/+1
| | | | | | | | | | | | | | | | hw/boards.h pulls in almost 60 headers. The less we include it into headers, the better. As a first step, drop superfluous inclusions, and downgrade some more to what's actually needed. Gets rid of just one inclusion into a header.

* hw/riscv: Load OpenSBI as the default firmwareAlistair Francis2019-07-181-0/+54
| | | | | | | | | | | | | If the user hasn't specified a firmware to load (with -bios) or specified no bios (with -bios none) then load OpenSBI by default. This allows users to boot a RISC-V kernel with just -kernel.
