[PATCH v5 00/11] riscv: OpenSBI boot test and cleanups

[Daniel Henrique Barboza <dbarboza@ventanamicro.com>]

Hi,

This new version is still rebased on top of [1]:

"[PATCH v2 00/12] hw/riscv: Improve Spike HTIF emulation fidelity"

from Bin Meng.

The change from v4 is on patch 9 where we added an extra flag in
riscv_load_kernel() to allow for boards that don't load initrd
(e.g. opentitan and sifive_e) to opt out from loading it altogether.

* Patch without reviews: 9

Changes from v4:
- patch 9:
  - added a 'load_init' flag in riscv_load_kernel() to control whether
    the function should execute riscv_load_initrd() or not
v4 link: https://lists.gnu.org/archive/html/qemu-devel/2022-12/msg04652.html

Changes from v3:
- patch 1:
  - fixed more instances of 'opensbi' and 'Opensbi' to 'OpenSBI'
  - changed tests order
- patch 4 (new):
  - added a g_assert(filename) guard in riscv_load_initrd() and
    riscv_load_kernel()
v3 link: https://mail.gnu.org/archive/html/qemu-devel/2022-12/msg04491.html 

Changes from v2:
- patch 1:
  - reduced code repetition with a boot_opensbi() helper
  - renamed 'opensbi' to 'OpenSBI' in the file header
- patch 9:
  - renamed riscv_load_kernel() to riscv_load_kernel_and_initrd()
v2 link: https://mail.gnu.org/archive/html/qemu-devel/2022-12/msg04466.html


Changes from v1:
- patches were rebased with [1]
- patches 13-15: removed
  * will be re-sent in a follow-up series
- patches 4-5: removed since they're picked by Bin in [1]
- patch 1:
  - added a 'skip' riscv32 spike test
v1 link: https://mail.gnu.org/archive/html/qemu-devel/2022-12/msg03860.html
