ARM: ixp4xx bug fixes
These were originally prepared by Krzysztof Halasa but not submitted in time for v3.7 due to some confusion about how ixp4xx patches should be handled. Jason Cooper thankfully offered to help out sending the patches upstream through arm-soc now, but given the timing, we could as well delay them for 3.8. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIVAwUAULdujWCrR//JCVInAQK5mA/+MTmqpabAIKAemk9CXZewNwJkdX2ILkce +WcxQwfD/7xWCsLxSwVgBrrUmXiw9/EwJBIGti6JgMEFtMD70DwooSNnRejN+cTz ZMJvoOzgRu5Q51SeX1V6x7xkNSVupMPEKt2ziBFUNyHCMTuEtZx8KXhmP5KTyP9e ZyAXgrWpsna9OefbFa2qkYvTA243NBEreRRpxUJe582Y84GEXWCL47eqgRoflXmV T+jPSCRsqcepxOnkCFYSmCp7J5EAQn1CcyfN11T8Jlj1Vr+ntjGtSKSQ6+uXxgqx /kTRnpdXJsogX9q6M/AzOkqTugB8jOvL8TIVo7AJDDS4fOSllzQdTEqagmPtkZdT jGavaEPy8F8mQOQJqmC9++AT0xhyiVhijAXSHxX1W+u9OmEw3+Mx/CTlR+QORr3p AVUlmmFrGna0vk3iL4Ov1rZu5D647nfTmTQE4fvhV37U2GEP4nqcF08kUl3V0idg xF1iEDBdtjgCOf2cCkTIj8X9xeuhoqVRdUp5w5Y8WrsfkzDigOgRJGgkJaafhymz bRcpbB3NVXbIUhB45VWI4j9KO0O9ysboWe6ibWdSl2/bTD0J/MDcqLkr8r9yPQYV IA8xuRE3/p+ZVt72YXAAuFSbwpVmLcZBX6vJuOvFR5gjFg1g1hAqQdBmFekh7QQZ 4S/xhOTTzLk= =GlCa -----END PGP SIGNATURE----- Merge tag 'ixp4xx-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM ixp4xx bug fixes from Arnd Bergmann: "These were originally prepared by Krzysztof Halasa but not submitted in time for v3.7 due to some confusion about how ixp4xx patches should be handled.

IXP4xx: Always ioremap() Queue Manager MMIO region at boot. ixp4xx: Declare MODULE_FIRMWARE usage IXP4xx crypto: MOD_AES{128,192,256} already include key size. WAN: Remove redundant HDLC info printed by IXP4xx HSS driver. IXP4xx: Remove time limit for PCI TRDY to enable use of slow devices. IXP4xx: ixp4xx_crypto driver requires Queue Manager and NPE drivers. IXP4xx: HW pseudo-random generator is available on IXP45x/46x only. IXP4xx: Fix off-by-one bug in Goramo MultiLink platform. IXP4xx: Fix Goramo MultiLink platform compilation.
