[PATCH 00/30] efi: refactor for upcoming loader support

[Ahmad Fatoum]

Nothing EFI loader support specific yet, just shifting around code to
enable future reuse, fixing some typos found along the way and improving
wide char support a bit.

Ahmad Fatoum (30):
  fs: remove useless AT_FDCWD references
  fs: remove unused struct node_d in struct dir
  block : efi: rename driver variable from efi_fs_driver to
    efi_bio_driver
  include: <linux/types.h>: wrap in #ifndef __ASSEMBLY__
  hw_random: stm32: propagate error codes from rng read
  efi: align LOAD_FILE_PROTOCOL_GUID's name with other PROTOCOL_GUIDs
  asm-generic: move sync_caches_for_execution declaration to
    <asm/cache.h>
  common: move EFI code into new efi/ top level directory
  serial: efi-stdio: move efi-stdio.h header to central location
  efi: use SPDX-License-Identifier where appropriate
  drivers: efi: move Kconfig options to new menu
  efi: factor out errno translation
  efi: rename <efi/efi.h> to <efi/efi-payload.h>
  efi: centralize efivarfs_parse_filename
  kbuild: force 16-bit wchar_t treewide
  include: <linux/nls.h>: remove duplicate wchar_t typedef
  lib: wchar: add wctomb and mbtowc
  lib: implement wcsnlen
  vsprintf: add optional support for %ls format modifier
  libfile: null-terminate read_file of wchar_t buffer
  commands: echo: add wide file output via wecho alias
  efi: make efi_main __noreturn
  efi: define and use new EFI_ERROR_MASK macro
  common: move CONFIG_ELF into General Settings
  efi: don't zero executable buffer before freeing
  partitions: efi: move header to central location
  efi: print early efi_main string on CONFIG_DEBUG_LL=y
  ARM64: board-dt-2nd: remove no longer needed noinline function split
  bus: acpi: register bus even if without ACPI EFI table
  efi: guid: fix typos
