efi_loader: implement EFI_RT_PROPERTIES_TABLE

2020-02-26T18:32:09+00:00

UEFI spec 2.8 errata A replaces the RuntimeServicesSupported variable
defined in UEFI spec 2.8 by the configuration table
EFI_RT_PROPERTIES_TABLE. So let's follow suit.

dm: core: Create a new header file for 'compat' features

2020-02-06T02:33:46+00:00

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.

Move the compatibility features into a separate header file.

common: Move ARM cache operations out of common.h

2019-12-02T23:24:58+00:00

These functions are CPU-related and do not use driver model. Move them to
cpu_func.h

crc32: Use the crc.h header for crc functions

2019-12-02T23:23:08+00:00

Drop inclusion of crc.h in common.h and use the correct header directly
instead.

With this we can drop the conflicting definition in fw_env.h and rely on
the crc.h header, which is already included.

efi_loader: do not call efi_runtime_detach twice

2019-08-15T18:33:10+00:00

Commit 7f95104d91cc ("efi_loader: detach runtime in ExitBootServices()")
added a call to efi_runtime_detach() to ExitBootServices() but did not
remove the call in SetVirtualAddressMap().

Remove the superfluous function call.

Correct a comment referring to efi_runtime_detach().

efi_loader: definition of efi_virtual_address_map()

Use efi_uintn_t where the UEFI spec uses UINTN. Use efi_uintn_t also for
the result of the division of two efi_uintn_t.

efi_loader: Change return type of efi_add_memory_map()

2019-07-16T22:17:17+00:00

We currently have some inconsistent use of efi_add_memory_map()
throughout the code. In particular the return value of efi_add_memory_map()
is not interpreted the same way by various users in the codebase.

This patch does the following:

- Changes efi_add_memory_map() to return efi_status_t.
- Adds a method description to efi_add_memory_map().
- Changes efi_add_memory_map() to return EFI_SUCCESS
- Returns non-zero for error in efi_add_memory_map()
- Updates efi_allocate_pages() to new efi_add_memory_map()
- Updates efi_free_pages() to new efi_add_memory_map()
- Updates efi_carve_out_dt_rsv() to new efi_add_memory_map()
- Updates efi_add_runtime_mmio()  to new efi_add_memory_map()
