【reason】
This is becasuse cpu ARM926T is not configured to support our board evb3504, that is to say, our board is not included into the range of supported development boards by cpu ARM926.
The cpu ARM926 supported borads are configured in “arch/arm/mm/Kconfig”

【method】
Add the support to evb3504 development board by ARM926.
Edit Kconfig: arch/arm/mm/Kconfig
# ARM926T
config CPU_ARM926T
       bool "Support ARM926T processor"
       depends on ARCH_INTEGRATOR || ARCH_VERSATILE_PB || MACH_VERSATILE_AB || ARCH_OMAP730 || ARCH_OMAP16XX || MACH_REALVIEW_EB || ARCH_PNX4008 || ARCH_NETX || CPU_S3C2412 || ARCH_AT91SAM9260 || ARCH_AT91SAM9261 || ARCH_EVB3504
       default y if ARCH_VERSATILE_PB || MACH_VERSATILE_AB || ARCH_OMAP730 || ARCH_OMAP16XX || ARCH_PNX4008 || ARCH_NETX || CPU_S3C2412 || ARCH_AT91SAM9260 || ARCH_AT91SAM9261 || ARCH_EVB3504
       select CPU_32v5
       select CPU_ABRT_EV5TJ
       select CPU_CACHE_VIVT
       select CPU_CP15_MMU
       select CPU_COPY_V4WB if MMU
       select CPU_TLB_V4WBI if MMU
       help
         This is a variant of the ARM920.  It has slightly different
         instruction sequences for cache and TLB operations.  Curiously,
         there is no documentation on it at the ARM corporate website.

         Say Y if you want support for the ARM926T processor.
         Otherwise, say N.
