efi: Correct ECPT table GUID

2025-01-05T01:30:49+00:00

Refer to UEFI specification 2.10:
  #define EFI_CONFORMANCE_PROFILES_TABLE_GUID \
  { 0x36122546, 0xf7e7, 0x4c8f, \
  { 0xbd, 0x9b, 0xeb, 0x85, 0x25, 0xb5, 0x0c, 0x0b }}

efi_loader: update EFI specification version

2025-01-05T01:30:49+00:00

UEFI specification 2.11 has been published.
There are no changes relevant for the U-Boot scope.
So let us update the supported specification version.

Change the comment for the constant to Sphinx style.

efi: Use the correct GUID for the SMBIOS table

2024-01-07T20:45:07+00:00

EFI does not use the 'anchor string' to determine the SMBIOS table
version, instead preferring to have two separate GUIDs. Use the correct
one, depending on the table version.

Call unmap_system() to balance to the use of map_sysmem()

efi_loader: add return to efibootmgr event group

2023-11-18T08:08:09+00:00

When the image loaded by efibootmgr returns, efibootmgr
needs to clean the resources. Adding the event of returning
to efibootmgr is useful to simplify the implementation.

efi_loader: add missing const classifier for event service

2023-11-18T08:08:09+00:00

const classifier is missing in EventGroup parameter of
CreateEventEx(). Fix it to remove the compiler warning.

NotifyContext parameter of CreateEventEx() is also defined
with const in UEFI specification, but NotifyContext parameter
of CreateEvent() is defined without const.
Since current implementation calls the common efi_create_event()
function from both CreateEventEx() and CreateEvent() services,
NotifyContext parameter leaves as is.

efi_loader: support all uclasses in device path

2023-07-20T07:12:50+00:00

On devices with multiple USB mass storage devices errors like

    Path /../USB(0x0,0x0)/USB(0x1,0x0)/Ctrl(0x0)
    already installed.

are seen. This is due to creating non-unique device paths. To uniquely
identify devices we must provide path nodes for all devices on the path
from the root device.

Add support for generating device path nodes for all uclasses.

efi_loader: Fix warnings for unaligned accesses

2023-05-13T09:09:51+00:00

Tom reports that when building with clang we see this warning:
field guid within 'struct efi_hii_keyboard_layout' is less aligned than 'efi_guid_t' and is usually due to 'struct efi_hii_keyboard_layout' being packed, which can lead to unaligned accesses [-Wunaligned-access]

This happens because 'struct efi_hii_keyboard_layout' is defined as
packed and thus has 1-byte alignment but efi_guid_t is a type that
requires greater alignment than that.

However the EFI spec describes the EFI_GUID as
"128-bit buffer containing a unique identifier value.
Unless otherwise specified"

So convert the efi_guid_t -> u8 b[16] here and skip the alignment
requirements.  Since the struct is packed to begin with, it makes no
difference on the final memory layout.
