+Subject: [PATCH v3] mtd: cfi_cmdset_0001: Byte swap OTP info
+
+Currently the offset into the device when looking for OTP
+bits can go outside of the address of the MTD NOR devices,
+and if that memory isn't readable, bad things happen
+on the IXP4xx (added prints that illustrate the problem before
+the crash):
+
+cfi_intelext_otp_walk walk OTP on chip 0 start at reg_prot_offset 0x00000100
+ixp4xx_copy_from copy from 0x00000100 to 0xc880dd78
+cfi_intelext_otp_walk walk OTP on chip 0 start at reg_prot_offset 0x12000000
+ixp4xx_copy_from copy from 0x12000000 to 0xc880dd78
+8<--- cut here ---
+Unable to handle kernel paging request at virtual address db000000
+[db000000] *pgd=00000000
+(...)
+
+This happens in this case because the IXP4xx is big endian and
+the 32- and 16-bit fields in the struct cfi_intelext_otpinfo are not
+properly byteswapped. Compare to how the code in read_pri_intelext()
+byteswaps the fields in struct cfi_pri_intelext.
+
+Adding a small byte swapping loop for the OTP in read_pri_intelext()
+and the crash goes away.
+
+The problem went unnoticed for many years until I enabled
+CONFIG_MTD_OTP on the IXP4xx as well, triggering the bug.

+ChangeLog v2->v3:
+- Move the byte swapping to a small loop in read_pri_intelext()
+ so all bytes are swapped as we reach cfi_intelext_otp_walk().
+ChangeLog v1->v2:
+- Drill deeper and discover a big endian compatibility issue.
