fsl: add register read-back to set_law()

After programming a new LAW, we should read-back the LAWAR register so that

ppc/85xx: Fix bug in setup_mp code

Its possible that we try and copy the boot page code out of flash into a
DDR location that doesn't have a TLB cover it. For example, if we have
3G of DDR we typically only map the first 2G. In the cases of 4G+ this
wasn't an issue since the reset page TLB mapping covered the last page
of memory which we wanted to copy to.

We now change the physical address of the reset page TLB to map to the
true physical location of the boot page code, copy and than set the
TLB back to its 1:1 mapping of the reset page.

ppc/85xx: Add a simple function to search the TLB

Allow us to search the TLB array based on an address. This is useful

we change the WIMGE settings for after we've relocated.

85xx: Add support for setting IVORs to fixed offset defaults

In future Book-E implementations IVORs will most likely go away and be

fsl_i2c: increase I2C timeout values and make them configurable

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.

Reset i2c slave devices during init on mpc5xxx cpus

Reset any i2c devices that may have been interrupted during a system reset.
Normally this would be accomplished by clocking the line until SCL and SDA
are released and then sending a start condtiion (From an Atmel datasheet).
There is no direct access to the i2c pins so instead create start commands
through the i2c interface. Send a start command then delay for the SDA Hold

atmel_df_pow2: standalone to convert dataflashes to pow2

Atmel DataFlashes by default operate with pages that are slightly bigger
than normal binary sizes (i.e. many are 1056 byte pages rather than 1024

up with the normal binary size.  The latter mode is required in order to
boot with a Blackfin processor, so many people wish to convert their
DataFlashes on their development systems to this mode.  This standalone

arm: Kirkwood: add SYSRSTn Duration Counter Support

This feature can be used to trigger special command "sysrstcmd" using
reset key long press event and environment variable "sysrstdelay" is set
(useful for reset to factory or manufacturing mode execution)

Kirkwood SoC implements a hardware-based SYSRSTn duration counter.
When SYSRSTn is asserted low, a SYSRSTn duration counter is running.
The counter value is stored in the SYSRSTn Length Counter Register
The counter is based on the 25-MHz reference clock (40ns)
It is a 29-bit counter, yielding a maximum counting duration of
2^29/25 MHz (21.4 seconds). When the counter reach its maximum value,
it remains at this value until counter reset is triggered by setting
bit 31 of KW_REG_SYSRST_CNT

Implementation:
Upon long reset assertion (> ${sysrstdelay} in secs) sysrstcmd will be
executed if pre-defined in environment variables.
This feature will be disabled if "sysrstdelay" variable is unset.

for-ex.
setenv sysrst_cmd "echo starting factory reset;
nand erase 0xa0000 0x20000;
echo finish ed sysrst command;"
will erase particular nand sector if triggered by this event

fsl: simplify the "mac id" command, improve boot-time informational message

The "mac id" command took a 4-character parameter as the identifier string.
However, for any given board, only one kind of identifier is acceptable, so it
makes no sense to ask the user to type it in.  Instead, if the user enters
"mac id", the identifier (and also the version, if it's NXID) will
automatically be set to the correct value.

Improve the message that is displayed when EEPROM is read during boot.  It now
displays "EEPROM:" and then either an error message or the EEPROM identifier
if successful.

If the identifier in EEPROM is valid, then always reject a bad CRC, even if the
CRC field has not been initialized.

Don't force the MAC address count to MAX_NUM_PORTS or less.  Forcing the value
to be changed resulting in an in-memory copy that does not match what's in
hardware, even though the user did not request that change.

Finally, always update the CRC value in the in-memory copy after any field
is changed, so that the CRC is always correct.

Also revamped and corrected few Freescale Copyright messages.

8xxx: Refactored common cpu specific code for 85xx/86xx into one file.

Removed same code pieces from cpu/mpc85xx/cpu.c and cpu/mpc86xx/cpu.c
and moved to cpu/mpc8xxx/cpu.c(new file)

86xx: Remove redudant PLATFORM_CPPFLAGS

For historic reasons we had defined some additional PLATFORM_CPPFLAGS like:

PLATFORM_CPPFLAGS += -DCONFIG_MPC86xx=1
PLATFORM_CPPFLAGS += -DCONFIG_MPC8641=1

However these are all captured in the config.h and thus redudant. Also
moved common 86xx flags into cpu/mpc86xx/config.mk.

pci/fsl_pci_init: Rework PCI ATMU setup to handle >4G of memory

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.

pci/fsl_pci_init: Use PCIe capability to determine if controller is PCIe

Change the code to use the PCIe capabilities register to determine if we
are a PCIe controller or not. Additionally cleaned up some white space

pci/fsl_pci_init: Fold fsl_pci_setup_inbound_windows into fsl_pci_init

Every platform that calls fsl_pci_init calls fsl_pci_setup_inbound_windows
before it calls fsl_pci_init. There isn't any reason to just call it
from fsl_pci_init and simplify things a bit.
