f7d190b1c0 85xx: Using proper I2C source clock divider for MPC8544
The MPC8544 RM incorrect shows the SEC_CFG bit in PORDEVSR2 as being
bit 26, instead it should be bit 28.  This caused in incorrect
interpretation of the i2c_clk which is the same as the SEC clk on
MPC8544.  The SEC clk is controlled by cfg_sec_freq that is reported
in PORDEVSR2.

c0391111c3 Fix the incorrect DDR clk freq reporting on 8536DS
On 8536DS board, When the DDR clk is set async mode(SW3[6:8] != 111),
The display is still sync mode DDR freq. This patch try to fix
this. The display DDR freq is now the actual freq in both
sync and async mode.

46497056ae mpc83xx: Store and display Arbiter Event Register values
Record the Arbiter Event Register values and optionally display them.

The Arbiter Event Register can record the type and effective address of
an arbiter error, even through an HRESET. This patch stores the values in
the global data structure.

Display of the Arbiter Event registers immediately after the RSR value
can be enabled with defines. The Arbiter values will only be displayed
if an arbiter event has occured since the last Power On Reset, and either
of the following defines exist:
 #define CONFIG_DISPLAY_AER_BRIEF - display only the arbiter address and
                                    and type register values
 #define CONFIG_DISPLAY_AER_FULL  - display and interpret the arbiter
                                    event register values

Address Only transactions are one of the trapped events that can register
as an arbiter event. They occur with some cache manipulation instructions
if the HID0_ABE (Address Broadcast Enable) is set and the memory region
has the MEMORY_COHERENCE WIMG bit set. Setting:
 #define CONFIG_MASK_AER_AO - prevents the arbiter from recording address
                              only events, so that it can still capture
                              other real problems.

58e5e9aff1 FSL DDR: Rewrite the FSL mpc8xxx DDR controller setup code.
The main purpose of this rewrite it to be able to share the same
initialization code on all FSL PowerPC products that have DDR
controllers.  (83xx, 85xx, 86xx).

The code is broken up into the following steps:
	GET_SPD
	COMPUTE_DIMM_PARMS
	COMPUTE_COMMON_PARMS
	GATHER_OPTS
	ASSIGN_ADDRESSES
	COMPUTE_REGS
	PROGRAM_REGS

This allows us to share more code an easily allow for board specific code
overrides.

Additionally this code base adds support for >4G of DDR and provides a
foundation for supporting interleaving on processors with more than one
controller.

5de851403b ppc4xx: Rework 440GX UIC handling
This patch reworks the 440GX interrupt handling so that the common 4xx
code can be used. The 440GX is an exception to all other 4xx variants
by having the cascading interrupt vectors not on UIC0 but on a special
UIC named UICB0 (UIC Base 0). With this patch now, U-Boot references
the 440GX UICB0 when UIC0 is selected. And the common 4xx interrupt
handling is simpler without any 440GX special cases.

Also some additional cleanup to cpu/ppc4xx/interrupt.c is done.

d1631fe1a0 ppc4xx: Consolidate PPC4xx UIC defines
This 2nd patch now removes all UIC mask bit definition. They should be
generated from the vectors by using the UIC_MASK() macro from now on.
This way only the vectors need to get defined for new PPC's.

Also only the really used interrupt vectors are now defined. This makes
definitions for new PPC versions easier and less error prone.

Another part of this patch is that the 4xx emac driver got a little
cleanup, since now the usage of the interrupts is clearer.

2e2050842e ppc4xx: Add Mnemonics for AMCC/IBM DDR2 SDRAM Controller
This patch completes the preprocessor mneomics for the IBM DDR2 SDRAM
controller registers (MODT and INITPLR) used by the
PowerPC405EX(r). The MMODE and MEMODE registers are unified with their
peer values used for the INITPLR MR and EMR registers,
respectively. Finally, a spelling typo is correct (MANUEL to MANUAL).

With these mnemonics in place, the CFG_SDRAM0_* magic numbers for
Kilauea are replaced by equivalent mnemonics to make it easier to
compare and contrast other 405EX(r)-based boards (e.g. during board
bring-up).

Finally, unified the SDRAM controller register dump routine such that
it can be used across all processor variants that utilize the IBM DDR2
SDRAM controller core. It produces output of the form:

	PPC4xx IBM DDR2 Register Dump:
		...
	        SDRAM_MB0CF[40] = 0x00006701
		...

which is '<mnemonic>[<DCR #>] = <value>'. The DCR number is included
since it is not uncommon that the DCR values in header files get mixed
up and it helps to validate, at a glance, they match what is printed
in the user manual.

Tested on:
  AMCC Kilauea/Haleakala:
  - NFS Linux Boot: PASSED
  - NAND Linux Boot: PASSED

While the PowerPC 405EX(r) shares in common the AMCC/IBM DDR2 SDRAM
controller core also used in the 440SP, 440SPe, 460EX, and 460GT, in
the 405EX(r), SDRAM_MCSTAT has a different DCR value.

Its present value on the 405EX(r) causes a read back of 0xFFFFFFFF
which causes SDRAM initialization to periodically fail since it can
prematurely indicate SDRAM ready status.

5d812b8b4a ppc4xx: Enable support for > 2GB SDRAM on AMCC Katmai
Newer PPC's like 440SPe, 460EX/GT can be equipped with more than 2GB of SDRAM.
To support such configurations, we "only" map the first 2GB via the TLB's. We
need some free virtual address space for the remaining peripherals like, SoC
devices, FLASH etc.

Note that ECC is currently not supported on configurations with more than 2GB
SDRAM. This is because we only map the first 2GB on such systems, and therefore
the ECC parity byte of the remaining area can't be written.

c821b5f120 ppc4xx: Enable Primordial Stack for 40x and Unify ECC Handling
This patch (Part 1 of 2):

* Rolls up a suite of changes to enable correct primordial stack and
  global data handling when the data cache is used for such a purpose
  for PPC40x-variants (i.e. CFG_INIT_DCACHE_CS).

* Related to the first, unifies DDR2 SDRAM and ECC initialization by
  eliminating redundant ECC initialization implementations and moving
  redundant SDRAM initialization out of board code into shared 4xx
  code.

* Enables MCSR visibility on the 405EX(r).

* Enables the use of the data cache for initial RAM on
  both AMCC's Kilauea and Makalu and removes a redundant
  CFG_POST_MEMORY flag from each board's CONFIG_POST value.

  - Removed, per Stefan Roese's request, defunct memory.c file for
    Makalu and rolled sdram_init from it into makalu.c.

With respect to the 4xx DDR initialization and ECC unification, there
is certainly more work that can and should be done (file renaming,
etc.). However, that can be handled at a later date on a second or
third pass. As it stands, this patch moves things forward in an
incremental yet positive way for those platforms that utilize this
code and the features associated with it.

c148f24c15 PPC: Change lib_ppc/bat_rw.c to use high bats
Currently, this code only deals with BATs 0-3, which makes
it useless on systems that support BATs 4-7.  Add the
support for these registers.
