When setting up the console via function efi_console_register() we call query_console_serial(). This functions sends an escape sequence to the terminal to query the display size. The response is another escape sequence. console.run_command_list() is looking for a regular expression '^==>'. If the escape sequence for the screen size precedes the prompt without a line break, no match is found. When efi_disk_register() is called before efi_console_register() this leads to a test failuere of the UEFI secure boot tests. We can avoid the problem if the first UEFI command passed to u_boot_console.run_command_list() produces output. This patch achieves this by appending '; echo' to the first UEFI related command of the problematic tests. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
