efi_loader: complete implementation of GetTime()

2018-07-25T13:00:24+00:00

Implement the missing parts of the GetTime() runtime service.

Fill seconds.
Fill daylight saving time flag correctly.
Provide dummy values for capabilities.

efi_loader: remove unused efi_get_time_init()

2018-07-25T13:00:24+00:00

Remove unused function efi_get_time_init().

Initialization of the RTC has to be done in board bring up not in the EFI
subsystem.

There is no RTC device in the UEFI spec. The RTC is only accessed through
the runtime services.

efi_loader: correct headersize EFI tables

2018-07-25T12:59:44+00:00

The headersize field has to be set to the size of the whole table
including the header.

efi_loader: specify UEFI spec revision

2018-07-25T12:59:44+00:00

Both in the boot and the runtime services tables we have to specify the
UEFI spec revision. The same value is already used for the system
table. So let's use a common constant.

In the boot services table we have to provide the header signature.

efi_loader: Use common elf.h reloc defines

2018-07-25T12:57:43+00:00

Now that elf.h contains relocation defines for all architectures
we care about, let's just include it unconditionally and refer to
the defines.

efi_loader: Move to compiler based target architecture determination

2018-07-25T12:57:43+00:00

Thanks to CONFIG_SANDBOX, we can not rely on config options to tell us
what CPU architecture we're running on.

The compiler however does know that, so let's just move the ifdefs over
to compiler based defines rather than kconfig based options.

efi: Add a comment about duplicated ELF constants

2018-06-14T08:52:14+00:00

These constants are defined in arch-specific code but redefined here. Add
a TODO to clean this up.

efi_loader: adjust definitions of variable services

2018-06-03T13:27:20+00:00

The definitons of the variable services are adjusted:
- use efi_uintn_t instead of unsigned long
- use u16 * instead of s16 * for Unicode strings
- correct definition of QueryVariableInfo
- rename efi_get_next_variable to efi_get_next_variable_name

efi_loader: Enable RISC-V support

2018-05-29T06:43:12+00:00

We have almost all pieces needed to support RISC-V UEFI binaries in place already.
The only missing piece are ELF relocations for runtime code and
data.

This patch adds respective support in the linker script and the runtime
relocation code. It also allows users to enable the EFI_LOADER configuration
switch on RISC-V platforms.
