[U-Boot] [PATCH 14/17] efi_loader: provide links between devices EFI handles

[Heinrich Schuchardt]

From: Heinrich Schuchardt <xypron.glpk at gmx.de>

U-Boot devices and EFI handles can be related, e.g. an
IDE disk relates to a handle with the EFI_BLOCK_IO_PROTOCOL.
Provide pointers to store these links.
