Before main memory (DDR) is initialized, the on-chip L1 cache is used as a
memory area for the stack and the global data (gd_t) structure.  This is
called the initial RAM area, or initram.  The L1 cache is locked and the TLBs
point to a non-existent address (so that there's no chance it will overlap
main memory or any device).  The L1 cache is also configured not to write
out to memory or the L2 cache, so everything stays in the L1 cache.

One of the things we might do while running out of initram is relocate CCSR.
On reset, CCSR is typically located at some high 32-bit address, like
0xfe000000, and this may not be the best place for CCSR.  For example, on
36-bit systems, CCSR is relocated to 0xffe000000, near the top of 36-bit
memory space.

On some future Freescale SOCs, the L1 cache will be forced to write to the
backing store, so we can no longer have the TLBs point to non-existent address.
Instead, we will point the TLBs to an unused area in CCSR.  In order for this
technique to work, CCSR needs to be relocated before the initram memory is
enabled.

Unlike the original CCSR relocation code in cpu_init_early_f(), the TLBs
we create now for relocating CCSR are deleted after the relocation is finished.
cpu_init_early_f() will still need to create a TLB for CCSR (at the new
location) for normal U-Boot purposes.  This is done to keep the impact to
existing U-Boot code minimal and to better isolate the CCSR relocation code.

Introduce the CONFIG_SYS_CCSRBAR_PHYS_HIGH and CONFIG_SYS_CCSRBAR_PHYS_LOW
macros, which contain the high and low portions of CONFIG_SYS_CCSRBAR_PHYS.
This is necessary for the assembly-language code that relocates CCSR, since
the assembler does not understand 64-bit constants.

CONFIG_SYS_CCSRBAR_PHYS is automatically defined from the
CONFIG_SYS_CCSRBAR_PHYS_HIGH and CONFIG_SYS_CCSRBAR_PHYS_LOW macros, so it
should not be defined in a board header file.  Similarly,
CONFIG_SYS_CCSRBAR_DEFAULT is defined for each SOC in config_mpc85xx.h, so
it should also not be defined in the board header file.

CONFIG_SYS_CCSR_DO_NOT_RELOCATE is a "short-cut" macro that guarantees that
CONFIG_SYS_CCSRBAR_PHYS is set to the same value as CONFIG_SYS_CCSRBAR_DEFAULT,
and so CCSR will not be relocated.

Since CONFIG_SYS_CCSRBAR_DEFAULT is locked to a fixed value, multi-stage U-Boot
builds (e.g. NAND) are required to relocate CCSR only during the last stage
(i.e. the "real" U-Boot).  All other stages should define
CONFIG_SYS_CCSR_DO_NOT_RELOCATE to ensure that CCSR is not relocated.

README is updated with descriptions of all the CONFIG_SYS_CCSRBAR_xxx macros.

This reverts commit 041c5422.

The lines removed by this commit weren't redundant. The logic is (and
probably should be better commented):

Find the intersection of the advertised capabilities of both sides of
the link (lpa).
From that intersection, find the highest capability we can run at
(that will be the negotiated link).

Now imagine that the intersection (lpa) is (LPA_100HALF | LPA_10FULL).

The code will now set phydev->speed to 100, and phydev->duplex to 1,
but this link does not support 100FULL.

Kudos to Andy Fleming <afleming@gmail.com> for binging this to
attention and for the explanation.
