2019-11-25hw/riscv: Add optional symbol callback ptr to riscv_load_kernel()Zhuang, Siwei (Data61, Kensington NSW)
This patch adds an optional function pointer, "sym_cb", to riscv_load_kernel() which provides the possibility to access the symbol table during kernel loading. The pointer is ignored, if supplied with Image or uImage file. The Spike board requires the access to locate the HTIF symbols.

2019-08-16include: Make headers more self-containedMarkus Armbruster
Back in 2016, we discussed[1] rules for headers, and these were generally liked: 1. Have a carefully curated header that's included everywhere first. We got that already thanks to Peter: osdep.h. 2. Headers should normally include everything they need beyond osdep.h. If exceptions are needed for some reason, they must be documented in the header. If all that's needed from a header is typedefs, put those into qemu/typedefs.h instead of including the header. 3. Cyclic inclusion is forbidden. This patch gets include/ closer to obeying 2. It's actually extracted from my "[RFC] Baby steps towards saner headers" series[2], which demonstrates a possible path towards checking 2 automatically. It passes the RFC test there.

2019-07-18hw/riscv: Load OpenSBI as the default firmwareAlistair Francis
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.
