Current eficonfig has the maximum number of menu entries and it is 99. If there are more EFI load options and files in the system, eficonfig can not handle it. This commit increases this maximum number of menu entries to INT_MAX. Signed-off-by: Masahisa Kojima <masahisa.kojima@linaro.org> Reviewed-by: Ilias Apalodimas <ilias.apalodimas@linaro.org>
