In -this mode, the content of the SPI flash chip -can be accessed via a memory mapped region. - -During early init time, the kernel expects -that the flash chip is accessible through -that memory region because it reads board -specific values (e.g. MAC address, WiFi -calibration data) from the flash on various -boards. - -This is working if the kernel is loaded -directly by the bootloader because that -leaves the SPI controller in the special -mode. However it is not working in a kexec'd -kernel because the SPI driver does not restore -the special mode during shutdown. - -The patch adds a shutdown handler to fix this -issue. - -Signed-off-by: Gabor Juhos <juhosg@openwrt.org> -Signed-off-by: Grant Likely <grant.likely@secretlab.ca> ---- - drivers/spi/spi-ath79.c | 6 ++++++ - 1 file changed, 6 insertions(+) - ---- a/drivers/spi/spi-ath79.c -+++ b/drivers/spi/spi-ath79.c -@@ -308,9 +308,15 @@ static int ath79_spi_remove(struct platf - return 0; - } - -+static void ath79_spi_shutdown(struct platform_device *pdev) -+{ -+ ath79_spi_remove(pdev); -+} -+ - static struct platform_driver ath79_spi_driver = { - .probe = ath79_spi_probe, - .remove = ath79_spi_remove, -+ .shutdown = ath79_spi_shutdown, - .driver = { - .name = DRV_NAME, - .owner = THIS_MODULE, |
