efi_loader: default EFI_LOADER=n on ARM11

2019-11-23T08:19:31+00:00

Some of the ARM11 boards have tight limits on the size of U-Boots. Hence
use EFI_LOADER=n as default on ARM11.

Set EFI_LOADER=y for the Raspberry Pi and Raspberry Pi Zero as these boards
have sufficient storage on the SD card.

efi_loader: enable EFI_LOADER on arm1136 and arm1176

2019-11-19T11:10:22+00:00

With an implementation for allow_unaligned() available for arm1136 and
arm1176 UEFI can be supported on these architectures.

efi_loader: restrict EFI_LOADER to armv7 and armv8 on ARM

2019-11-19T11:10:22+00:00

fatload USB was reported to fail on the Sheevaplug. Debugging showed that
this was caused by an incorrect unaligned write to memory in
path_to_uefi().

UEFI on ARM requires that unaligned memory access is enabled.

* ARMv5 does not support unaligned access at all.
* ARMv6 supports unaligned access when we clear the A flag and set the
  U flag.
* On ARMv7 unaligned access is possible when clearing the aligned flag,
  which we do in function allow_unaligned() (arch/arm/cpu/armv7/sctlr.S).
  For none of the other cpus in arch/arm/cpu/ we have implemented a
  similar function.
* ARMv8 allows unaligned access.

Let EFI_LOADER on ARM depend on SYS_CPU=armv7 or SYS_CPU=armv8.

Once we have implemented allow_unaligned() for other ARM CPUs we can add
these to Kconfig.

efi_loader: re-enable GRUB workaround on 32bit ARM

2019-07-30T19:36:22+00:00

GRUB on ARM 32bit prior to version 2.04 lacks proper handling of caches.
In U-Boot v2019.04 a workaround for this was inadvertently removed.

The workaround is currently also needed for booting on systems with caches
that cannot be managed via CP15 (e.g. with an i.MX6 CPU).

Re-enable the workaround and make it customizable.

efi_loader: decision on EFI_RT_SUPPORTED_RESET_SYSTEM

2019-07-06T19:25:32+00:00

Move the logic determining which board supports reset at runtime to Kconfig.

efi_loader: Kconfig entries for GetTime(), SetTime()

2019-06-01T02:53:13+00:00

The GetTime() and the SetTime() runtime services are not obligatory. So
let's make them customizable.

efi_loader: implement deprecated Unicode collation protocol

2019-05-19T06:10:10+00:00

In EFI 1.10 a version of the Unicode collation protocol using ISO 639-2
language codes existed. This protocol is not part of the UEFI specification
any longer. Unfortunately it is required to run the UEFI Self Certification
Test (SCT) II, version 2.6, 2017. So we implement it here for the sole
purpose of running the SCT. It can be removed once a compliant SCT is
available.

The configuration option defaults to no.

Signed-off-by: Rob Clark 

Most of Rob's original patch is already merged. Only the deprecated
protocol is missing. Rebase it and make it configurable.

efi_loader: rename Unicode collation protocol 2 variables

Rename variables to make it clear they refer to the Unicode collation
protocol identified by the EFI_UNICODE_PROTOCOL2_GUID.

efi_loader: make device path to text protocol customizable

efi_loader: make Unicode collation protocol customizable

2019-05-12T18:54:22+00:00

The Unicode collation protocol is not needed for EBBR compliance. So let's
make it a customizable option.

The Unicode capitalization table is only needed by this protocol. So let it
depend on the Unicode collation protocol.
