[U-Boot] [PATCH v2 0/3] efi_loader: add removable device support

[AKASHI Takahiro]

Under the current implementation, any removable device which is
attached to the platform will not be recognized after any efi-related
command, in particular bootefi, is once executed.

This patch set resolves this problem by re-scanning and recreating
a disk device list for efi operations.

# I didn't run selftest "block device" as I don't know how we can
# create a test disk image.
# Heinrich, can you provide a script?

-Takahiro Akashi

Changes in v2 (Nov 15, 2018)
* efi_init_obj_list() will never return an error once it has succeeded
* add "invalid" flag to efi_disk to indicate that a given device
  is now in stale state
* modify block io protocol and file protocol to honor invalid flag
* simplify efi simple file system protocol/file procotol by removing
  details of an u-boot block device
* some function were renamed after Heinrich's comment

AKASHI Takahiro (3):
  efi_loader: export efi_locate_handle() function
  efi_loader: enumerate disk devices every time
  efi_loader: remove block device details from efi file
