d4bd2ca2aa powerpc/km8321: define CONFIG_SYS_DDRCDR
On the km8321 boards is CONFIG_SYS_DDRCDR not defined, which leads to
the DDRCDR not being configured at startup and still containing the
reset value.

The required settings for our km8321 hardware designs are different than
the reset value and must be set with CONFIG_SYS_DDRCDR, that is used
by mpc83xx's cpu_init_f function at early CPU initialization.

The important settings are the DDR2 internal voltage level and the
half-strength "drivers".

In our case where the DRAM chips are soldered on board and the routing
for these signals under control, half-strength is sufficient as a few
measurements done in the lasts have shown. Since all the hardware
qualification tests have been performed with half strength, the nominal
strength settings are removed in favor of the default reset half
strength settings.

09f3ca3dd5 arm, powerpc: select SYS_GENERIC_BOARD
We have finished Generic Board conversion for ARM and PowerPC, i.e.
all the boards have been converted except OpenRISC, SuperH, SPARC,
which have not supported Generic Board framework yet.

Select SYS_GENERIC_BOARD in arch/Kconfig and delete all the macro
defines in include/configs/*.h.

fdfaa29e49 mpc83xx: preempt premature board support removal by setting GENERIC_BOARD
Boards that haven't been converted to GENERIC_BOARD does
*not* mean they should be removed.

25b29921b2 powerpc/83xx/km: remove uneeded CONFIG_MISC_INIT_R
Remove it from the processor specific headers. This is
already defined in the common header km83xx.h.

513e396b4f powerpc/83xx/km: update SDRAM parameters for km8321 boards
Measurements during HW basic test showed, that the SDRAM timing
has to be optimized. This patch adapted these timings accordingly.

b648bfc212 km/common: simplify debug environment
The debug environment which is stored in textfiles in the
scripts directory was reworked. Two usecase are now present
which can be executed simply from the default environment:
run develop: this configures the environment to setup the
             rootfs via nfs
run ramfs: this configures the environment to setup the
           rootfs in ram

Each architecture now has a "arch" variable which is used
to load the architecture specific debug scripts and to set
the rootpath for NFS.
