Without this, a 'break' instruction is executed very early in the boot and
the boot hangs.

The problem is that clang doesn't honour named registers on local variables
and silently treats them as normal uninitialized variables. However, it
does honour them on global variables.

Some hardware blocks attached to the OCTEON bootbus run asynchronously
to accesses from the CPUs.  These include MMC/SD host, CF(when using
DMA), and NAND controller.  A bus error, or corrupt data may occur if
a CPU is trying to access a bootbus connected device at the same time
the bus is running asynchronous operations.

To work around these problems we add this semaphore that must be
acquired before initiating bootbus activity.  Subsequent patches will
add users for this.

Enabling support for more than one BMIPS CPU in the same build may
result in different L1_CACHE_SHIFT values, e.g.

    CPU_BMIPS4380 selects MIPS_L1_CACHE_SHIFT_6
    anything else defaults to MIPS_L1_CACHE_SHIFT_5

Ensure that if more than one MIPS_L1_CACHE_SHIFT_x option is selected,
Kconfig sets CONFIG_MIPS_L1_CACHE_SHIFT to the highest value.
