The ESRT is initialised during efi_init_objlist after efi_initialize_system_table().
The ESRT is initially created with size for 50 FW image entries. The ESRT is resized when it runs out of space. Every resize adds 50 additional entries. The ESRT is populated from information provided by FMP instances only.

<josem> one limitation is, if any FMP instance is installed and then uninstalled during the same boottime flow, the ESRT entries will not be removed <josem> this limitation is because I cannot find a proper UEFI way to hook to a FMP protocol uninstall. <xypron> register an event with RegisterProtocolNotify(). <xypron> EFI_CALL(efi_register_protocol_notify(...)) after exporting the function in /include/efi_loader <xypron> The event can be created with efi_create_event().
