Modified Files:
src/sys/arch/arm/arm: bus_space_asm_generic.S
Log Message:
To quote the BCM2835 datasheet that's publicly available
"The BCM2835 system uses an AMBA AXI-compatible interface
structure. In order to keep the system complexity low and data
throughput high, the BCM2835 AXI system does not always
return read data in-order."
Deal with this by defining DSB for _ARM_ARCH_6.
