-Subject: [PATCH] spi/ath79: add shutdown handler
-
-commit 7410e848583f9120dd5f9414629f01bb76b5ee5f upstream.
-
-The SPI controller of the AR7xxx/AR9xxx SoCs
-have a special mode which allows the SoC to
-directly read data from SPI flash chips. 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.
