efi_loader: comments for efi_install_fdt()

2019-05-12T18:54:23+00:00

Describe that efi_install_fdt() defaults to using the device tree
indicated by environment variable fdtcontroladdr.

ACPI tables and device trees are mutually exclusive.

efi_loader: clean up UEFI sub-system initialization

2019-05-07T19:10:03+00:00

allow_unaligned(), switch_to_non_secure_mode(), and efi_init_obj_list() are
called in sequence in multiple places.

Move calls to allow_unaligned() and switch_to_non_secure_mode() to
efi_init_obj_list().

Remove unused includes.

efi_loader: implement support of exit data

2019-05-02T16:17:50+00:00

In case of a failure exit data may be passed to Exit() which in turn is
returned by StartImage().

Let the `bootefi` command print the exit data string in case of an error.

efi_loader: set OsIndicationsSupported at init

2019-05-02T16:17:49+00:00

UEFI variables should be installed using well-defined API.
Currently we don't support much, but the value of OsIndicationsSupported
will be updated once some features are added in the future.

Signed-off-by: AKASHI Takahiro 

Add comments. Rename a variable.

efi_loader: need either ACPI table or device tree

2019-04-22T22:37:28+00:00

The EBBR specification prescribes that we should have either an ACPI table
or a device tree but not both. Let us enforce this condition in the
`bootefi` command.

If the bootefi command is called without a device tree parameter use a
previously device tree or fall back to the internal device tree.

The fdt unit test should not be run on boards with an ACPI table.

efi_loader: rework bootmgr/bootefi using load_image API

2019-04-22T22:37:28+00:00

In the current implementation, bootefi command and EFI boot manager
don't use load_image API, instead, use more primitive and internal
functions. This will introduce duplicated code and potentially
unknown bugs as well as inconsistent behaviours.

With this patch, do_efibootmgr() and do_boot_efi() are completely
overhauled and re-implemented using load_image API.

Signed-off-by: AKASHI Takahiro 

Use efi_root as parent handle for the loaded image.
LoadImage() should be called with BootPolicy = true by the boot manager.
Avoid duplicate free_pool().
Eliminate variable memdp which is not needed after anymore due to
"efi_loader: correctly split device path of loaded image".

cmd: bootefi: carve out do_bootefi_image() from do_bootefi()

2019-04-22T22:37:28+00:00

This is a preparatory patch for reworking do_bootefi() in later patch.
All the non-boot-manager-based (that is, bootefi ) code is put
into one function, do_bootefi_image().

cmd: bootefi: carve out bootmgr code from do_bootefi()

This is a preparatory patch for reworking do_bootefi() in later patch.
do_bootmgr_exec() is renamed to do_efibootmgr() as we put all the necessary
code into this function.
