Alex, It seems to me that the current efi_runtime_detach() has two meanings: * changes relating to the transition to virtual address mode * changes relating to exiting boot services
In the current implementation, efi_runtime_detach() is called from efi_set_virtual_address_map() as those two purposes are apparently the same. For instance, however, systab.con_in/out/std_err/boottime are set to NULL in exit_boot_services() as well. Logically, efi_get_variable() won't work as U-Boot environment data can be potentially re-used at any time after exit_boot_services(). The only meaningful change is to invalidate efi_set_virtual_address_map(). So I believe that we should distinguish the two purposes and make appropriate changes in efi_set_virtual_address_map() and and exit_boot_services() respectively. This will be crucial particularly when I will add runtime variable support using "cache". Any thoughts?
