efi_loader: new function efi_delete_handle()

2017-12-16T22:07:36+00:00

Provide a function to remove a handle from the object list
after removing all protocols.

To avoid forward declarations other functions have to move up
in the coding.

efi_loader: return status from efi_setup_loaded_image()

2017-12-16T22:07:25+00:00

efi_setup_loaded_image() should return an error code indicating if
an error has occurred.

An error occurs if a protocol cannot be installed.

efi_loader: helper function to add EFI object to list

2017-12-01T12:41:01+00:00

To avoid duplicate coding provide a helper function that
initializes an EFI object and adds it to the EFI object
list.

efi_exit() is the only place where we dereference a handle
to obtain a protocol interface. Add a comment to the function.

efi_loader: efi_console: use helper functions

2017-12-01T12:22:56+00:00

Use helper functions efi_created_handle and efi_add_protocol
for creating the console handles and instaling the respective
protocols.

This change is needed if we want to move from an array of
protocols to a linked list of protocols.

Eliminate EFI_PROTOCOL_OBJECT which is not used anymore.

Currently we have not defined protocol interfaces to be const.
So efi_con_out and efi_console_control cannot be defined as const.

efi_loader: helper functions for protocol management

2017-12-01T12:22:56+00:00

This patch provides helper functions to manage protocols.
efi_search_protocol - find a protocol on a handle
efi_add_protocol - install a protocol on a handle
efi_remove_protocol - remove a protocol from a handle
efi_remove_all_protocols - remove all protocols from a handle

efi_loader: argument of efi_search_obj should be const

The argument of efi_search_obj is not changed so it should
be marked as const.

efi_loader: rework efi_search_obj

2017-12-01T12:22:56+00:00

EFI_HANDLEs are used both in boottime and in runtime services.
efi_search_obj is a function that can be used to validate
handles. So let's make it accessible via efi_loader.h.

We can simplify the coding using list_for_each_entry.
