efi_loader: update runtime services table crc32

2018-08-20T12:43:12+00:00

The crc32 of the runtime services table must be updated after detaching.

efi_update_table_header_crc32() must be __efi_runtime. So move it to
efi_runtime.c

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: allocate configuration table array

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

The system table contains a link to the list of configurations tables.
These include the device tree, SMBIOS table, and the ACPI table.

This array is currently statically linked. With the patch it is allocated
as EFI_RUNTIME_SERVICES_DATA. Due to the structure of the system table we
cannot work with a linked list here.

For the boot and runtime services tables and for the system table the
crc32 has to be set in the header.

efi_loader: Rename sections to allow for implicit data

2018-07-25T12:57:44+00:00

Some times gcc may generate data that is then used within code that may
be part of an efi runtime section. That data could be jump tables,
constants or strings.

In order to make sure we catch these, we need to ensure that gcc emits
them into a section that we can relocate together with all the other
efi runtime bits. This only works if the -ffunction-sections and
-fdata-sections flags are passed and the efi runtime functions are
in a section that starts with ".text".

Up to now we had all efi runtime bits in sections that did not
interfere with the normal section naming scheme, but this forces
us to do so. Hence we need to move the efi_loader text/data/rodata
sections before the global *(.text*) catch-all section.

With this patch in place, we should hopefully have an easier time
to extend the efi runtime functionality in the future.

ACPI tables can be passed via EFI configuration table to an EFI
application. This is only supported on x86 so far.

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: Use EFI_CACHELINE_SIZE in the image loader too

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

We were using our EFI_CACHELINE_SIZE define only in the runtime service
code, but left the image loader to use plain CONFIG_SYS_CACHELINE_SIZE.

This patch moves EFI_CACHELINE_SIZE into efi_loader.h and converts
the image loader to use it.
