From 570147275c00ce64e0aaa956b1dff73c7422985d Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Sun, 8 Dec 2019 10:02:37 +0100 Subject: [PATCH] efi_loader: adjust file system info When the GetInfo() method of the EFI_FILE_PROTOCOL is called to retrieve the file system info we claim that the volume is read only and has no free space. This leads to failures in programs that check this information before writing to the volume like SCT's InstallSct.efi. Currently there is no function to determine these parameters in U-Boot. So let's return optimistic values: Return that the volume is writable. Return the volume size as free space.
