6eb2a44e27 mpc83xx: clean up cache operations and unlock_ram_in_cache() functions
Cleans up some latent issues with the data cache control so that
dcache_enable() and dcache_disable() will work reliably (after
unlock_ram_in_cache() has been called)

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.

ade50c7fa1 mpc83xx: use r4 instead of r2 in lock_ram_in_cache and unlock_ram_in_cache
This is needed in unlock_ram_in_cache() because it is called from C and
will corrupt the small data area anchor that is kept in R2.

lock_ram_in_cache() is modified similarly as good coding practice, but
is not called from C.

d9fe88173c MPC83XX: Fix GPIO configuration - set gpio level before direction
Set DAT value before DIR values to avoid creating glitches on the
GPIO signals.

Set gpio level register before direction register to inhibit
glitches on high level output pins.

Dir and data gets cleared at powerup, so high level output lines see
a short low pulse between setting the direction and level registers.

Issue was seen on a new board with the nReset line of the NOR flash
connected to a GPIO. Setting the direction register puts the NOR flash
in reset so the next instruction to set the level cannot get executed.

75b9d4ae0d Pass in tsec_info struct through tsec_initialize
The tsec driver contains a hard-coded array of configuration information
for the tsec ethernet controllers.  We create a default function that works
for most tsecs, and allow that to be overridden by board code.  It creates
an array of tsec_info structures, which are then parsed by the corresponding
driver instance to determine configuration.  Also, add regs, miiregs, and
devname fields to the tsec_info structure, so that we don't need the kludgy
"index" parameter.

846f1574dd fix system config overwrite @ MPC834x and MPC8313
During 83xx setup the "System I/O configuration register high" gets
overwritten with user defined value if CFG_SICRH is defined.

Regarding to the MPC834x manual (Table 5-28 reve.1) bits 28+29 of SICRH
must keep their reset value regardless of configuration.

On my board (using RGMII) those bits are set after reset - yet it's
unclear where they come from.

The patch keeps both bits on MPC834x and MPC8313.

5bbeea86eb mpc8323erdb: Improve the system performance
The following changes are based on kernel UCC ethernet performance:

1.  Make the CSB bus pipeline depth as 4, and enable the repeat mode
2.  Optimize transactions between QE and CSB.  Added CFG_SPCR_OPT
    switch to enable this setting.

The following changes are based on the App Note AN3369 and
verified to improve memory latency using LMbench:

3.  CS0_CONFIG[AP_n_EN] is changed from 1 to 0
4.  CS0_CONFIG[ODT_WR_CONFIG] set to 1.  Was a reserved setting
    previously.
5.  TIMING_CFG_1[WRREC] is changed from 3clks to 2clks  (based on
    Twr=15ns, and this was already the setting in DDR_MODE)
6.  TIMING_CFG_1[PRETOACT] is changed from 3clks to 2clks. (based on
    Trp=15ns)
7.  TIMING_CFG_1[ACTTOPRE] is changed from 9clks to 6clks. (based on
    Tras=40ns)
8.  TIMING_CFG_1[ACTTORW] is changed from 3clks to 2clks. (based on
    Trcd=15ns)
9.  TIMING_CFG_1[REFREC] changed from 21 clks to 11clks.  (based on
    Trfc=75ns)
10. TIMING_CFG_2[FOUR_ACT] is changed from 10 clks to 7clks.  (based
    on Tfaw=50ns)
11. TIMING_CFG_2[ADD_LAT] and DDR_MODE[AL] changed from 0 to 1 (based
    on CL=3 and WL=2).

e7670f6c1e PPC: Use r2 instead of r29 as global data pointer
R29 was an unlucky choice as with recent toolchains (gcc-4.2.x) gcc
will refuse to use load/store multiple insns; instead, it issues a
list of simple load/store instructions upon function entry and exit,
resulting in bigger code size, which in turn makes the build for a
few boards fail.

64134f0112 Fix linker scripts: add NOLOAD atribute to .bss/.sbss sections
With recent toolchain versions, some boards would not build because
or errors like this one (here for ocotea board when building with
ELDK 4.2 beta):
ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab]

For many boards, the .bss section is big enough that it wraps around
at the end of the address space (0xFFFFFFFF), so the problem will not
be visible unless you use a 64 bit tool chain for development. On
some boards however, changes to the code size (due to different
optimizations) we bail out with section overlaps like above.

The fix is to add the NOLOAD attribute to the .bss and .sbss
sections, telling the linker that .bss does not consume any space in
the image.
