+Subject: ANDROID: scsi: ufs: Add quirk bit for controllers that don't play
+ well with inline crypto
+
+A number of devices (hikey960 and db845c at least) don't work
+well with the inline crypto enablement, causing them to crash in
+early boot.
+
+In order to allow those boards to continue booting, add a
+BROKEN_CRYPTO quirk flag that the drivers can enable until we
+sort out how/if they can be fixed.

+Subject: ANDROID: scsi: ufs-hisi: Enable BROKEN_CRYPTO quirk flag
+
+HiKey960 doesn't play well with the inline crypto logic, and
+seems to deviate from the UFS standard.
+
+Eric Biggers noted:
+"It declares that it has 32 crypto configurations (a.k.a.
+keyslots), starting at offset 1280 from the start of the UFS
+registers.  Per the UFS standard, each crypto configuration is
+128 bytes, so that means they go until offset 5376.
+
+However, the device tree node for the UFS host controller (in
+hi3660.dtsi) only declares 4096 bytes for the UFS standard
+registers, and then the next 4096 physical bytes are declared to
+be vendor-specific UFS registers.  The ufs-hisi driver already
+uses these vendor-specific registers to do things like reset the
+UFS controller and configure the clocks.  But if we follow the
+UFS standard, the very same memory addresses have a different
+meaning.
+
+Also, even if I hardcode the number of keyslots to 22 so they fit
+in the first 4096 bytes, then there is either an SError interrupt
+while programming keyslot 0, or CRYPTO_GENERAL_ERROR is reported
+from the UFS request."
+
+So until we can understand the hardware better disable inline
+crypto using the quirks flag in the driver.
