armv8: Support loading 32-bit OS in AArch32 execution state

2016-11-22T19:40:24+00:00

To support loading a 32-bit OS, the execution state will change from
AArch64 to AArch32 when jumping to kernel.

The architecture information will be got through checking FIT image,
then U-Boot will load 32-bit OS or 64-bit OS automatically.

efi_loader: AArch64: Run EFI payloads in EL2 if U-Boot runs in EL3

2016-11-17T10:52:21+00:00

Some boards decided not to run ATF or other secure firmware in EL3, so
they instead run U-Boot there. The uEFI spec doesn't know what EL3 is
though - it only knows about EL2 and EL1. So if we see that we're running
in EL3, let's get into EL2 to make payloads happy.

efi: Add support for a hello world test program

2016-11-14T22:24:03+00:00

It is useful to have a basic sanity check for EFI loader support. Add a
'bootefi hello' command which loads HelloWord.efi and runs it under U-Boot.

This should use U-Boot's standard format for hex address. Fix it.

efi_loader: Revert device_handle to disk after net boot

2016-10-19T07:01:54+00:00

When you boot an efi payload from network, then exit that payload
and load another payload from disk afterwords, the disk payload will
currently see the network device as its boot path.

This breaks grub2 for example which tries to find its modules based
on the path it was loaded from.

This patch fixes that issue by always reverting to disk paths if we're
not in the network boot. That way the data structures after a network
boot look the same as before.

smbios: Expose in efi_loader as table

2016-10-19T07:01:52+00:00

We can pass SMBIOS easily as EFI configuration table to an EFI payload. This
patch adds enablement for that case.

While at it, we also enable SMBIOS generation for ARM systems, since they support
EFI_LOADER.

efi_loader: Allow boards to implement get_time and reset_system

2016-10-18T07:08:08+00:00

EFI allows an OS to leverage firmware drivers while the OS is running. In the
generic code we so far had to stub those implementations out, because we would
need board specific knowledge about MMIO setups for it.

However, boards can easily implement those themselves. This patch provides the
framework so that a board can implement its own versions of get_time and
reset_system which would actually do something useful.

While at it we also introduce a simple way for code to reserve MMIO pointers
as runtime available.

efi_loader: disk: Fix CONFIG_BLK breakage

2016-08-08T17:32:59+00:00

When using CONFIG_BLK, there were 2 issues:

  1) The name we generate the device with has to match the
     name we set in efi_set_bootdev()

  2) The device we pass into our block functions was wrong,
     we should not rediscover it but just use the already known
     pointer.

This patch fixes both issues.
