| * spi: spi_flash: Fix the arguments of stm_is_locked_sr()Fabio Estevam2016-01-07-2/+2
| | | | | | | | | | | | | | | | | | | | | | stm_is_locked_sr() takes the status register (SR) value as the last parameter, not the second. Based on a patch from Brian Norris for the linux kernel: http://git.infradead.org/linux-mtd.git/commit/a32d5b726ff8cf32bf491522b0ac8ae2545a063e Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com> Reviewed-by: Jagan Teki <jteki@openedev.com>

This enables main spl code to make the decision whether to hang or not, thus preparing it to support alternative boot devices. Some boot devices (namely nand and spi) do not hang on error. Instead, they return normally and SPL proceeds to boot the contents of the load address. This is considered a bug and is rectified by hanging on error for these devices as well.
