-Subject: [PATCH] bcm2835-sdhost: Add debug_flags dtparam
-
-Bit zero disables the single-read-sectors map:
-
-If the default MMC driver is bcm2835-mmc:
-    dtoverlay=sdhost,debug_flags=1
-If the default MMC driver is bcm2835-sdhost:
-    dtoverlay=sdtweak,debug_flags=1
-(although the sdhost overlay may also work, sdtweak is
-less invasive and will work in more circumstances).
-
-Also revert the timeout change, just in case.
