[PATCH 0/7] efi: Various tidy-ups and drop the default

It has come to light that EFI_LOADER adds an extraordinary amount of
code to U-Boot. For example, with nokia_rx51 the size delta is about
90KB. About 170 boards explicitly disable the option, but is is clear
that many more could, thus saving image size and boot time.

The current situation is affecting U-Boot's image as a svelt bootloader.

EFI_LOADER is required by EBBR, a new boot standard which aims to
bring in UEFI protocols to U-Boot. But EBRR is not required for
booting. U-Boot already provides support for FIT, the 'bootm' command
and a suitable hand-off to Linux. EBRR has made the decision to create
a parallel infrastructure, e.g. does not use FIT, nor U-Boot's signing
infrastructure.

EBBR should be truly optional, enabled only by boards that use it. Most
don't use it but it is enabled anyway. The default boot path should be
one that makes use of the existing U-Boot support.

To try to retify this situation, this series adds a new Kconfig option
for EBBR so that the naming is more explicit. Then EFI_LOADER is updated
to depend on it.

For now, only sandbox enables EBBR. Other boards can be added as needed,
presumably by distributions that require it. Another approach would be
to add 'CONFIG_EBBR=y' to the .config before building, in the build
system. That might be more friendly to U-Boot users.

This series also fixes a minor issue noticed during testing.
