This series aims at improving RISC-V spike machine BIOS support by allowing
use of binary firmware as bios. Further, this also allows us to totally
remove the ELF bios images shipped with QEMU RISC-V.
These patches can also be found in riscv_spike_imp_v2 branch at:
Now that RISC-V Spike machine can use BIN BIOS images, we remove
the macros used for ELF BIOS image names.

In the next commit we will use the dma_addr_t type in the QEMUSGList
structure. Since currently dma_addr_t is defined after QEMUSGList,
move the declarations to have dma_addr_t defined first. This is a
pure code-movement patch.

In commit c599d4d6d6e9bfdb64 in 2016 we renamed the old force_sig()
function to dump_core_and_abort(), but we forgot to rename the
associated tracepoint. Rename the tracepoint to to match the
function it's called from.

These can be replaced by a single field "uint32_t ecx".
You can add also macros like
#define ESA_FEATURE_ALIGN64_BIT (1)
#define ESA_FEATURE_XFD_BIT (2)
to simplify access.

memory_region_is_mapped() currently does not return "true" when a memory
region is mapped via an alias.
Assuming we have:
alias (A0) -> alias (A1) -> region (R0)
Mapping A0 would currently only make memory_region_is_mapped() succeed
on A0, but not on A1 and R0.

We do mention the limitation of single parenthood for
memory_region_add_subregion but lets also make it clear how aliases
help solve that conundrum.

Since commit 292e13142d2, dma_buf_rw() returns a MemTxResult type.
Do not discard it, return it to the caller. Pass the previously
returned value (the QEMUSGList residual size, which was rarely used)
as an optional argument.
With this new API, SCSIRequest::residual

The 'resid' field is slightly confusing and could be
interpreted as some ID. Rename it as 'residual' which
is clearer to review. No logical change.
