[U-Boot] [RFC 0/3] efi_loader: allow writing to FAT

Running UEFI Self-Certifcation Test (SCT) will require to support
writing to a FAT file system.

Writing to the FAT root directory from EFI fails because the leading
slash of the file path is interpreted as part of the filename.

With the 1st patch we can write to the root directory.

A unit test for writing a new file to the FAT root directory is supplied.

I am still unhappy that we cannot write to subdirectories. I therefore
mark the series as RFC.

Heinrich Schuchardt (3):
  fs: fat: cannot write to subdirectories
  efi_selftest: imply FAT, FAT_WRITE
  efi_selftest: test writing to file
