__i2c_read always ends with a STOP condition thereby releasing
the bus. It is cleaner to do the STOP magic in i2c_read(), like
i2c_write() does. This may also help future multimaster systems which
wants to hold on to the bus until all transactions are finished.

After issuing a STOP one must wait until the STOP has completed
on the bus before doing something new to the controller.
Also add an extra read of SR as the manual mentions doing that
is a good idea.
Remove surplus write of CR just before a write, isn't required and
could potentially disturb the I2C bus.

On CoreNet based platforms the LAW address is split between an high &
low register and we no longer shift the address. Also, the target IDs
on CoreNet platforms have been completely re-assigned.
Additionally, added a new find_law() API to which LAW an address hits in.
This is need for the CoreNet style boot release code since it will need
to determine what the target ID should be set to for boot window
translation.
Finally, enamed LAWAR_EN to LAW_EN and moved to header so we can use
it elsewhere.

The MPC8536E is capable of booting form NAND/eSDHC/eSPI, this patch
implements these three bootup methods in a unified way - all of these
use the general cpu/mpc85xx/start.S, and load the main image to L2SRAM
which lets us use the SPD to initialize the SDRAM.
For all three bootup methods, the bootup process can be divided into two
stages: the first stage will initialize the corresponding controller,
configure the L2SRAM, then copy the second stage image to L2SRAM and
jump to it. The second stage image is just like the general U-Boot image
to configure all the hardware and boot up to U-Boot command line.
When boot from NAND, the eLBC controller will first load the first stage
image to internal 4K RAM buffer because it's also stored on the NAND
flash. The first stage image, also call 4K NAND loader, will initialize
the L2SRAM, load the second stage image to L2SRAM and jump to it. The 4K
NAND loader's code comes from the corresponding nand_spl directory, along
with the code twisted by CONFIG_NAND_SPL.
When boot from eSDHC/eSPI, there's no such a first stage image because
the CPU ROM code does the same work. It will initialize the L2SRAM
according to the config addr/word pairs on the fixed address and
initialize the eSDHC/eSPI controller, then load the second stage image
to L2SRAM and jump to it.
The macro CONFIG_SYS_RAMBOOT is used to control the code to produce the
second stage image for all different bootup methods. It's set in the
board config file when one of the bootup methods above is selected.

This patch cleans up multiple issues of the 4xx register (mostly
DCR, SDR, CPR, etc) definitions:
- Change lower case defines to upper case (plb4_acr -> PLB4_ACR)
- Change the defines to better match the names from the
user's manuals (e.g. cprpllc -> CPR0_PLLC)
- Removal of some unused defines
Please test this patch intensive on your PPC4xx platform. Even though
I tried not to break anything and tested successfully on multiple
4xx AMCC platforms, testing on custom platforms is recommended.

The value of I2C_TIMEOUT in fsl_i2c.c has several problems. First, it is
defined as CONFIG_HZ/4, but it is used as a count of microseconds, so it makes
no sense to derive it from a clock rate. Second, the current value (250) is
too low for some boards, so it needs to be increased. Third, the timeout
necessary for multiple-master arbitration is larger than the timeout for basic
read/write operations, so we shouldn't have a single constant for both timeouts.
Finally, it would be nice if we could override these values on a per-board
basis.

- 256Kbyte L2 cache
- Ethernet controllers with classification capabilities.

The old PCI ATMU setup code would just mimic the PCI regions into the
ATMU registers. For simple memory maps in which all memory, MMIO, etc
space fit into 4G this works ok. However there are issues with we have
>4G of memory as we know can't access all of memory and we need to
ensure that PCICSRBAR (PEXCSRBAR on PCIe) isn't overlapping with
anything since we can't turn it off.
We first setup outbound windows based on what the board code setup
in the pci regions for MMIO and IO access. Next we place PCICSRBAR
below the MMIO window. After which we try to setup the inbound windows
to map as much of memory as possible.
On PCIe based controllers we are able to overmap the ATMU setup since
RX & TX links are separate but report the proper amount of inbound
address space to the region tracking to ensure there is no overlap.
On PCI based controllers we use as many inbound windows as available to
map as much of the memory as possible.
Additionally we changed all the CCSR register access to use proper IO
accessor functions. Also had to add CONFIG_SYS_CCSRBAR_PHYS to some
86xx platforms that didn't have it defined.

chips. This ECC mode is similar to NAND_ECC_HW, with the exception of
read_page API that first reads the OOB area, reads the data in chunks,
feeds the ECC from OOB area to the ECC hw engine and perform any
correction on the data as per the ECC status reported by the engine.
