The patch series introduces the following:
- the minimal set of headers and changes inside them.
- SBI (RISC-V Supervisor Binary Interface) things necessary for basic
  early_printk implementation.
- things needed to set up the stack.
- early_printk() function to print only strings.
- RISC-V smoke test which checks if  "Hello from C env" message is
  present in serial.tmp

The patch series is rebased on top of the patch "include/types: move
stddef.h-kind types to common header" [1]

Changes in V7:
  - Fix dependecy for qemu-smoke-riscv64-gcc job
---
Changes in V6:
  - Remove patches that were merged to upstream:
      * xen/include: Change <asm/types.h> to <xen/types.h>
      * xen/riscv: introduce asm/types.h header file
      * xen/riscv: introduce sbi call to putchar to console
  - Remove __riscv_cmodel_medany check from early_printk.C
  - Rename container name in test.yaml for .qemu-riscv64.
---
Changes in V5:
  - Code style fixes
  - Remove size_t from asm/types after rebase on top of the patch
    "include/types: move stddef.h-kind types to common header". [1]

    All other types were back as they are used in <xen/types.h>
  - Update <xen/early_printk.h> after rebase on top of [1] as size_t was moved from
    <asm/types.h> to <xen/types.h>
  - Remove unneeded <xen/errno.h> from sbi.c
  - Change an error message of #error in case of __riscv_cmodel_medany isn't defined
---
Changes in V4:
    - Patches "xen/riscv: introduce dummy asm/init.h" and "xen/riscv: introduce
      stack stuff" were removed from the patch series as they were merged separately
      into staging.
    - Remove "depends on RISCV*" from Kconfig.debug as Kconfig.debug is located
      in arch specific folder.
    - fix code style.
    - Add "ifdef __riscv_cmodel_medany" to early_printk.c.  
---
Changes in V3:
    - Most of "[PATCH v2 7/8] xen/riscv: print hello message from C env"
      was merged with [PATCH v2 3/6] xen/riscv: introduce stack stuff.
    - "[PATCH v2 7/8] xen/riscv: print hello message from C env" was
      merged with "[PATCH v2 6/8] xen/riscv: introduce early_printk basic
      stuff".
    - "[PATCH v2 5/8] xen/include: include <asm/types.h> in
      <xen/early_printk.h>" was removed as it has been already merged to
      mainline staging.
    - code style fixes.
---
Changes in V2:
    - update commit patches commit messages according to the mailing
      list comments
    - Remove unneeded types in <asm/types.h>
    - Introduce definition of STACK_SIZE
    - order the files alphabetically in Makefile
    - Add license to early_printk.c
    - Add RISCV_32 dependecy to config EARLY_PRINTK in Kconfig.debug
    - Move dockerfile changes to separate config and sent them as
      separate patch to mailing list.
    - Update test.yaml to wire up smoke test
