common: Drop asm/global_data.h from common header

2021-02-02T20:33:42+00:00

Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include  at all, so
remove that include.

efi_loader: don't set EFI_RT_SUPPORTED_UPDATE_CAPSULE

2020-12-10T08:15:32+00:00

The EFI_RT_PROPERTIES_TABLE configuration table indicates which runtime
services are available at runtime.

Even if CONFIG_EFI_RUNTIME_UPDATE_CAPSULE=y, we neither support
UpdateCapsule() nor QueryCapsuleCapabilities() at runtime. Thus we should
not set the corresponding flags EFI_RT_SUPPORTED_UPDATE_CAPSULE and
EFI_RT_SUPPORTED_QUERY_CAPSULE_CAPABILITIES in RuntimeServicesSupported.

efi_loader: define UpdateCapsule api

2020-12-03T20:22:49+00:00

In this commit, skeleton functions for capsule-related API's are
added under CONFIG_EFI_UPDATE_CAPSULE configuration.
Detailed implementation for a specific capsule type will be added
in the succeeding patches.

Adjust the SetTime() and GetTime() runtime services to correctly convert
the daylight saving time information when communicating with the RTC.

efi_loader: ResetSystem() should not hang

2020-08-24T14:37:53+00:00

If ResetSystem() is not implemented at runtime, it should return instead
of hanging in an endless loop. This allows the operating system to reset
the system by other means as Linux does. It also matches what EDK II
suggests in comments for functions ResetShutdown() and ResetWarm() in
OvmfPkg/Library/ResetSystemLib/ResetSystemLib.c.

efi_loader: don't use memmove() in efi_var_mem_del()

2020-07-22T10:32:41+00:00

efi_var_mem_del() is in __efi_runtime because it would be needed for a
runtime implementation of SetVariable(). memmove() is not in __efi_runtime.
So we should not use it in efi_var_mem_del().

Provide a memcpy() function that we can use at UEFI runtime.

efi_loader: optional pointer for ConvertPointer

2020-07-11T21:14:17+00:00

If the EFI_OPTIONAL_PTR is set in DebugDisposition, a NULL pointer does not
constitute an invalid parameter.

efi_loader: export efi_convert_pointer()

2020-07-11T21:14:17+00:00

We need ConvertPointer() to adjust pointers when implementing  runtime
services within U-Boot.

After ExitBootServices() gd is not available anymore. So we should not use
EFI_ENTRY() and EFI_EXIT().
