At the very least when USB keyboard support is enabled, we need to enable CONFIG_SYS_STDIO_DEREGISTER, so the "usb reset" is able to re-scan USB ports and find new devices. Enable it everywhere per request from Simon Glass.
Signed-off-by: Stephen Warren swarren@nvidia.com --- v2: Always enable the option, and hence do so in a different file.
Since v1 missed the v2015.04 release, here's v2 that implements the "post release" request from Simon right from the get-go. --- include/configs/tegra-common.h | 3 +++ 1 file changed, 3 insertions(+)
