    * NEWS: Mention corrected spelling of armv6kz.
    * config/tc-arm.c (arm_cpus): Replace ARM_ARCH_V6ZK with
    ARM_ARCH_V6KZ.
    (arm_archs): Likewise. Also add "armv6kz" and "armv6kzt2".
    * doc/c-arm.texi: Replace "armv6zk" with "armv6kz".

gas/testsuite

    * gas/arm/attr-march-armv6kz.d: New.
    * gas/arm/attr-march-armv6kzt2.d: New.

include/opcode

    * arm.h (ARM_AEXT_V6ZK): Rename to ARM_AEXT_V6KZ.
    (ARM_AEXT_V6ZKT2): Rename to ARM_AEXT_V6KZT2.
    (ARM_ARCH_V6ZK): Rename to ARM_ARCH_V6KZ.
    (ARM_ARCH_V6ZKT2): Rename to ARM_ARCH_V6KZT2.

 Changes in 2.26:
 
+* Added the correctly spelled -march=armv6kz, for ARMv6KZ support.  The
+  previous spelling, -march=armv6zk, is still accepted.
+
 * Support for the ARMv8.1 architecture has been added to the Aarch64 port.
   Support for the individual ARMv8.1 Adv.SIMD, LOR and PAN architecture
   extensions has also been added to the Aarch64 port.
