+Subject: [PATCH] USB: OHCI: allow other arches to use the BE frame number
+ quirk
+
+Intead of guarding it with a certain PPC SoC and expanding the list
+for each SoC requiring it, just guard it with USB_OHCI_BIG_ENDIAN_DESC.
+
+This makes it less suprising that passing no_big_frame_no = 1 for the
+platform data does not do what expected (or
+
+Checking it for all big endian descriptor setups should not impact
+performance much as USB1.1 is rather slow anyway.
