42c9a494f1 mpc83xx: Get rid of CONFIG_SYS_LBC_*
Except for one counter example, CONFIG_SYS_LBC_LBCR always has a value
of either 0x00040000 or 0x00000000.

CONFIG_SYS_LBC_MRTPR always has the value 0x20000000.

CONFIG_SYS_LBC_LSDMR_{1,2,4,5} are not set for any mpc83xx board.

CONFIG_SYS_LBC_LSRT is set by one board (to 0x32000000).

To simplify the configuration files, hardcode the setting of these
values for mpc83xx.

133ec60284 mpc83xx: Get rid of CONFIG_SYS_DDR_SDRAM_BASE
CONFIG_SYS_DDR_SDRAM_BASE is set to the same value as
CONFIG_SYS_SDRAM_BASE on all existing boards. Just use
CONFIG_SYS_SDRAM_BASE instead.

8a81bfd271 mpc83xx: Get rid of CONFIG_SYS_DDR_BASE
CONFIG_SYS_DDR_BASE is specific to mpc83xx an is always set to the same
value as CONFIG_SYS_SDRAM_BASE. Just use CONFIG_SYS_SDRAM_BASE instead.

fe7d654d04 mpc83xx: Migrate CONFIG_SYS_{BR, OR}*_PRELIM to Kconfig
Migrate the BR/OR settings to Kconfig. These must be known at compile
time, so cannot be configured via DT.

Configuration of this crucial variable should still be somewhat
comfortable. Hence, make its fields configurable in Kconfig, and
assemble the final value from these.

a8f975391f mpc83xx: Simplify BR,OR lines
Re-format all BR,OR #define lines into single lines. This makes them
harder to read, but accessible to semi-automatic replacement.

5d2f4c9641 mpc83xx: Normalize BR/OR option lines
All BR/OR option lines should have the same layout to make them easier
to migrate to Kconfig. This includes using the same option macros
everywhere.

The normalize the lines,
* replace function macros with their results, and
* replace hardcoded hex values with standard macros

9c5df7a2a9 mpc83xx: Migrate LBLAW_* to Kconfig
The LBLAW_* values determine the window configuration of the memory
controller. Hence, they must be known at compile time, and cannot be
implemented in the DT mechanism.

The BATs (block address translation registers) determine the initial
memory window mappings. Hence, they must be known at compile time and
cannot be implemented in the DT mechanism.

21c1502a4a mpc83xx: Kconfig: Migrate HRCW to Kconfig
The HRCW (hardware reset configuration word) is a constant that must be
hard-coded into the boot loader image. So, it must be available at
compile time, and cannot be migrated to the DT mechanism, but has to be
kept in Kconfig.

comfortable. Hence, make its fields configurable in Kconfig, and

ff3bb0c435 mpc83xx: Get rid of CONFIG_83XX_CLKIN
MPC83xx uses CONFIG_83XX_CLKIN instead of CONFIG_SYS_CLK_FREQ to set the
system clock. To migrate the architecture, we can replace
CONFIG_83XX_CLKIN with CONFIG_SYS_CLK_FREQ.

To do this
* replace all occurrences of CONFIG_83XX_CLKIN with CONFIG_SYS_CLK_FREQ
* set CONFIG_SYS_CLK_FREQ to the old value of CONFIG_83XX_CLKIN in all
  MPC83xx config files

904c47fc7d mpc83xx: Make distinct caddy2 config
vme8349.h contains two separate boards: The vme8349 itself, and the
caddy2 board. The caddy2 board is chosen by setting certain config
variables. Create a proper config file for the caddy2 board to make
Kconfig migration easier.

Furthermore, simplify the vme8349 and caddy2 configs by keeping only the
options necessary for each board.
