| * usbgadget: fastboot: Allow to automatically export the bbu handlersSascha Hauer2017-09-272-0/+19
| | | | | | | | | | | | | | | | | | | | We have a list of registered handlers which take a barebox update. Do the next step and allow to automatically export them via fastboot so that barebox can be updated via fastboot without manually exporting the partition. Since this may not be desirable in all cases this behaviour is configurable. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | file_list_parse() can fail and returns an error pointer. Print an error message when it fails and also set to NULL again so that usb_multi_register() does not stumble upon the error pointer. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We already have the MTD_SPI_NOR_USE_4K_SECTORS option handling in C code for 4K erase block support. Alas this 4K erase block support code can't be used because the MTD_SPI_NOR_USE_4K_SECTORS option support is missed in Kconfig.
