03d344bb6a ppc4xx: Make 440SPe PCIe code more generic to use on different 4xx PPCs (3)
(3) This patch introduces macros like SDRN_PESDR_DLPSET(port) to access
    the SDR registers of the PCIe ports. This makes the overall design
    clearer, since it removed a lot of switch statements which are not
    needed anymore.

    Also, the functions ppc4xx_init_pcie_rootport() and
    ppc4xx_init_pcie_entport() are merged into a single function
    ppc4xx_init_pcie_port(), since most of the code was duplicated.
    This makes maintainance and porting to other 4xx platforms
    easier.

7f19139389 [PPC440SPe] Improve PCIe configuration space access
- correct configuration space mapping
- correct bus numbering
- better access to config space

Prior to this patch, the 440SPe host/PCIe bridge was able to configure only the
first device on the first bus. We now allow to configure up to 16 buses;
also, scanning for devices behind the PCIe-PCIe bridge is supported, so
peripheral devices farther in hierarchy can be identified.

15ee4734e4 [PPC440SPe] Convert machine check exceptions handling
Convert using fixup mechanism to suppressing MCK for the duration of config
read/write transaction: while fixups work fine with the case of a precise
exception, we identified a major drawback with this approach when there's
an imprecise case. In this scenario there is the following race condition:
the fixup is (by design) set to catch the instruction following the one
actually causing the exception; if an interrupt (e.g. decrementer) happens
between those two instructions, the ISR code is executed before the fixup
handler the machine check is no longer protected by the fixup handler as it
appears as within the ISR code. In consequence the fixup approach is being
phased out and replaced with explicit suppressing of MCK during a PCIe
config read/write cycle.

c924098122 [ppc440SPe] Graceful recovery from machine check during PCIe configuration
During config transactions on the PCIe bus an attempt to scan for a
non-existent device can lead to a machine check exception with certain
peripheral devices. In order to avoid crashing in such scenarios the
instrumented versions of the config cycle read routines are introduced, so
the exceptions fixups framework can gracefully recover.

2ad3aba01d ppc4xx: Fix i2c divisor calcularion for PPC4xx
This patch fixes changes the i2c_init(...) function to use the function
get_OPB_freq() rather than calculating the OPB speed by
sysInfo.freqPLB/sysInfo.pllOpbDiv. The get_OPB_freq() function is
specific per processor. The prior method was not and so was calculating
the wrong speed for some PPC4xx processors.

00cdb4ce5e [PATCH] Update AMCC Luan 440SP eval board support
The AMCC Luan now uses the common 440SP(e) DDR SPD code for DDR
inititializition. This includes DDR auto calibration and support
for different DIMM modules, instead of the fixed setup used in
the earlier version.

This patch also enables the cache in FLASH for the startup
phase of U-Boot (while running from FLASH). After relocating to
SDRAM the cache is disabled again. This will speed up the boot
process, especially the SDRAM setup, since there are some loops
for memory testing (auto calibration).

e2ebe69681 [PATCH] Fix AMCC 44x SPD SDRAM init code to support 2 DIMM's
This patch fixes a problem that occurs when 2 DIMM's are
used. This problem was first spotted and fixed by Gerald Jackson
<gerald.jackson@reaonixsecurity.com> but this patch fixes the
problem in a little more clever way.

This patch also adds the nice functionality to dynamically
create the TLB entries for the SDRAM (tlb.c). So we should
never run into such problems with wrong (too short) TLB
initialization again on these platforms.

As this feature is new to the "old" 44x SPD DDR driver, it
has to be enabled via the CONFIG_PROG_SDRAM_TLB define.

Modifications are based on the linux kernel approach and
support two use cases:

  1) Add O= to the make command line
  'make O=/tmp/build all'

  2) Set environement variable BUILD_DIR to point to the desired location
  'export BUILD_DIR=/tmp/build'
  'make'

The second approach can also be used with a MAKEALL script
'export BUILD_DIR=/tmp/build'
'./MAKEALL'

Command line 'O=' setting overrides BUILD_DIR environent variable.

When none of the above methods is used the local build is performed and
the object files are placed in the source directory.

62534beb2f Updates to common PPC4xx onboard (DDR)SDRAM init code (405 and 440)
405 SDRAM: - The SDRAM parameters can now be defined in the board
             config file and the 405 SDRAM controller values will
             be calculated upon bootup (see PPChameleonEVB).
             When those settings are not defined in the board
             config file, the register setup will be as it is now,
             so this implementation should not break any current
             design using this code.

             Thanks to Andrea Marson from DAVE for this patch.

440 DDR:   - Added function sdram_tr1_set to auto calculate the
             TR1 value for the DDR.
           - Added ECC support (see p3p440).

3d9569b232 Changed PPC44x startup message (cpu info, speed...) to common style:
On PPC44x platforms, the startup message generated in "cpu.c" only
comprised the ppc type and revision but not additional informations
like speed etc. Those speed infos where printed in the board specific
code. This new implementation now prints all CPU infos in the common
cpu specific code. No board specific code is needed anymore and
therefore removed from all current 44x implementations.
