Initial support is enough to boot to a serial console, execute a minimal
set of U-Boot commands, download data over a serial port, and boot a
Linux kernel. No storage or network drivers are implemented.

86c632651d ARM: arm1176: enable instruction cache in arch_cpu_init()
Note that this affects all users of the ARM1176 CPU that enable
CONFIG_ARCH_CPU_INIT, not just the BCM2835 SoC, potentially such as
tnetv107x.
