[PATCH 49/75] ARM: l2c: fix register naming

[PATCH 49/75] ARM: l2c: fix register naming

[Russell King]

We have a mixture of different devices with different register layouts,
but we group all the bits together in an opaque mess.  Split them out
into those which are L2C-310 specific and ones which refer to earlier
devices.  Provide full auxiliary control register definitions.

[PATCH 51/75] ARM: l2c: remove platforms/SoCs setting early BRESP

[Russell King]

Since we now automatically enable early BRESP in core L2C-310 code when
we detect a Cortex-A9, we don't need platforms/SoCs to set this bit
explicitly.  Instead, they should seek to preserve the value of bit 30
in the auxiliary control register.
