This series implements the OpenProtocolInformation, ConnectController, and DisconnectController boot services.
The EFI application creating a new device will call ConnectController to request the installation of all necessary drivers. Before deleting the device it will call DisconectController to remove all child controllers and to detach the driver.
E.g. iPXE may be used to connect an iSCSI target. It then creates a handle by installing the EFI_BLOCK_IO_PROTOCOL. It calls ConnectController and expects U-Boot to create the partition handles and to provide the EFI_SIMPLE_FILE_SYSTEM_PROTOCOL. (The driver connecting to the EFI_BLOCK_IO_PROTOCOL is not yet implemented in U-Boot.)
A self test is provided for the driver management. The bootefi selftest now creates colored output. Two bug fixes are included.
To complete the implementation of the EFI boot services the following future work is needed: * manage events in a linked list (see Rob's proposal) * implement ReinstallProtocol and RegisterProtocolNotify
