The "autoload" environment variable is always checked with env_get_yesno as it can be set to any form of no. The default behavior of env_get_yesno is to return -1 on variables that are not set, which acts as true in general (we test for non-zero return). To convert CONFIG_SYS_AUTOLOAD to Kconfig, given that it was almost always used to set autoload to no, first rename to CONFIG_SYS_DISABLE_AUTOLOAD for consistency sake. Then, make it so that if enabled we set autoload=0 in the default environment. Migrate all platforms which set CONFIG_SYS_AUTOLOAD to non-true or that set autoload to false in their default environment to using CONFIG_SYS_DISABLE_AUTOLOAD Signed-off-by: Tom Rini <trini@konsulko.com>
