Current patch series introduces device tree mapping for RISC-V
and necessary things for that such as:
- Fixmap mapping
- pmap
- Xen page table processing
---
Changes in v8:
- The following patch was merged to staging:
[PATCH v5 1/7] xen/riscv: use {read,write}{b,w,l,q}_cpu() to define {read,write}_atomic()
- All other changes are patch specific so please look at the patch.
---
Changes in v7:
- Drop the patch "xen/riscv: prevent recursion when ASSERT(), BUG*(), or panic() are called"
- All other changes are patch specific so please look at the patch.
---
Changes in v6:
- Add patch to fix recursion when ASSERT(), BUG*(), panic() are called.
- Add patch to allow write_atomic() to work with non-scalar types for consistence
with read_atomic().
- All other changes are patch specific so please look at the patch.
---
Changes in v5:
- The following patch was merged to staging:
[PATCH v3 3/9] xen/riscv: enable CONFIG_HAS_DEVICE_TREE
- Drop depedency from "RISCV basic exception handling implementation" as
it was meged to staging branch.
- All other changes are patch specific so please look at the patch.
---
Changes in v4:
- Drop depedency from common devicre tree patch series as it was merged to
staging.
- Update the cover letter message.
- All other changes are patch specific so please look at the patch.
---
Changes in v3:
- Introduce SBI RFENCE extension support.
- Introduce and initialize pcpu_info[] and __cpuid_to_hartid_map[] and functionality
to work with this arrays.
- Make page table handling arch specific instead of trying to make it generic.
- All other changes are patch specific so please look at the patch.
---
Changes in v2:
- Update the cover letter message
- introduce fixmap mapping
- introduce pmap
- introduce CONFIG_GENREIC_PT
- update use early_fdt_map() after MMU is enabled.

Would it be helpful if I will send revision log as a reply to each
patch? Or it would be better just to re-send the patch series?

To me the one for 6/7 is relevant, to aid review. Sending that as reply
will be okay I guess. Patches 1-5 went in a few minutes ago anyway.

accommodate for an apparent debugging patch you have in your tree.
Please can you make sure to submit patches against plain staging, or
to clearly state dependencies?

I am always trying not to forget to rebase on top of staging for this
patch series:

xen/riscv: introduce early_fdt_map()

3ffb3ffd38 xen/riscv: introduce functionality to work with CPU info
4bfd2bfdb2 xen/riscv: introduce asm/pmap.h header
87bc91db10 xen/riscv: set up fixmap mappings
09b925f973 xen/riscv: allow write_atomic() to work with non-scalar
types
625ee7650c xen/README: add compiler and binutils versions for RISC-V64

0111c86bfa x86/boot: Refactor BIOS/PVH start
Only some patches have been merged today to staging on top of "blkif:
Fix a couple of typos".
It shouldn't be any issue with applying patches from these patch
series.

This looks to be a mix of several series. And "xen/riscv: test basic
exception handling stuff" looks to be what the problem was with, as that
wasn't committed yet (and imo also shouldn't be committed, as expressed
before; of course you can try to find someone else to approve it).
