autoboot.c: Add feature to stop autobooting via SHA256 encrypted password
This patch adds the feature to only stop the autobooting, and therefor boot into the U-Boot prompt, when the input string / password matches a values that is encypted via a SHA256 hash and saved in the environment. This feature is enabled by defined these config options: CONFIG_AUTOBOOT_KEYED CONFIG_AUTOBOOT_STOP_STR_SHA256 Signed-off-by: Stefan Roese <sr@denx.de> Reviewed-by: Simon Glass <sjg@chromium.org>
