Subject: [PATCH v3] xen/riscv: PE/COFF image header for RISC-V target
Added riscv image header to enable boot from second stage bootloaders (e.g.
uboot. Image header defined in riscv-image-header.h)
Additionally, RISC-V xen image is extended with PE/COFF headers, introducing
EFI application format.
PE/COFF header is optionally included (with CONFIG_RISCV_EFI) so
both plain ELF and image with PE/COFF header can now be generated as build
artifacts.
Note that this patch represents initial EFI application format support (image
contains EFI application header embeded into binary when CONFIG_RISCV_EFI
is enabled). For full EFI application Xen support, boot/runtime services
and system table handling are yet to be implemented.
Tested on both QEMU and StarFive VisionFive 2 with OpenSBI->U-Boot->xen->dom0
boot chain.

Changes since v2:
* Restructured EFI image headers - generic PE/COFF headers moved to
xen/include/efi/pe.h, riscv image header left in arch specific dir
(riscv/include/asm/riscv-image-header.h)
* EFI PE/COFF header section moved to separate file (efi-header.S) and
optionally included into image (head.S) if CONFIG_RISCV_EFI is enabled
* Removed explicit usage of compressed (c.*) instructions where not necessary
to avoid dependency on C extension.
* Removed redundant parts of code which were originally taken over from linux
kernel, but not used in this case
(data directories definition in optional PE header, _init_end_efi in linker
script)
* Removed nested code, explained pe header fields mapping and current EFI
support status
* Clarified riscv image header which is inserted into image regardless EFI
option value (in order to support boot from second stage bootloaders for both
ELF and EFI image format)
---
Changes since v1 (following review comments from Jan Beulich):
* Fix coding style
* Extended image header with all the necessary
PE/COFF (EFI) fields (instead of only those used by U-boot)
* Removed usage of deprecated types
