To support OF_EMBED, the MPC83xx architecture has to define the "_end"
symbol to correctly access the appended DT.
Fortunately, MPC8xx already defines the symbol, and the linker script is
quite similar to that of MPC83xx, so copy this approach for MPC83xx.

Lots of stuff in processor.h was taken verbatim from the Linux kernel.
It was never synced, so most of it was removed or changed in the kernel
since it was imported.
Remove all the stuff that is unused in the current U-Boot sources;
should anybody feel the need to re-sync with the kernel, they can do it
later on.

For a lot of inline assembly calls in the mpc8xxx and mpc83xx

but they're not used, resulting in hard-to-read code.

ppcDWstore/ppcDWload are hardly used by any board, but since they're

Re-implement these fuctions in C with inline assembly, so that the
compiler can decide when to actually include them.

The MPC83xx DM timer driver disables arch.pciexp*_clk, and uses

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
Signed-off-by: Mario Six <mario.six@gdsys.cc>
CONFIG_SYS_CLK_FREQ is the standard way to set the system clock
frequency. On MPC83xx, CONFIG_83XX_CLKIN is used for this purpose.
Hence, the obvious way is to replace CONFIG_83XX_CLKIN with
CONFIG_SYS_CLK_FREQ.
A few MPC83xx boards use the CONFIG_83XX_CLKIN variable for computing
CONFIG_SYS_NS16550_CLK. This makes it harder to replace
CONFIG_83XX_CLKIN.
But the value of the multiplicator can be read from the SPMR register.
Hence, replace the static calculations with a call to a new get_bus_freq
function, as other architectures do.

The LSDMR_* macros are used to configure the system bus on MPC83xx.
A few of the possible LSDMR_* macros were never defined in the
respective include files. This renders the SDRAM support on the

To make the SDRAM option work, introduce these macros into the proper
config file.
