powerpc, 8xx: remove support for 8xx

Browse Source 
There was for long time no activity in the 8xx area.
We need to go further and convert to Kconfig, but it
turned out, nobody is interested anymore in 8xx,
so remove it (with a heavy heart, knowing that I remove
here the root of U-Boot).

* CONFIG_SYS_MONITOR_BASE, while others (narrower address mask) can't
* map CONFIG_SYS_MONITOR_BASE.
*
* For example, for CONFIG_IVMS8, the CONFIG_SYS_MONITOR_BASE is

* have been narrowed to 512Kb, so CONFIG_SYS_MONITOR_BASE wasn't mapped
* into the Bank0.
*
* This is why CONFIG_IVMS8 and similar boards must load BR0 with
* CONFIG_SYS_BR0_PRELIM in advance.

* Measure CPU clock speed (core clock GCLK1, GCLK2),

*
* Initializes timer 2 and PIT, but disables them before return.
* [Use timer 2, because MPC823 CPUs mask 0.x do not have timers 3 and 4]
*
* When measuring the CPU clock against the PIT, we count cpu clocks
* for 58/8192 seconds with a prescale divide by 177 for the cpu clock.
* These strange values for the timing interval and prescaling are used
* because the formula for the CPU clock is:
*
* CPU clock = count * (177 * (8192 / 58))
*
* = count * 24999.7241
*
* which is very close to
*
* = count * 25000
*
* Since the count gives the CPU clock divided by 25000, we can get
* the CPU clock rounded to the nearest 0.1 MHz by
*
* CPU clock = ((count + 2) / 4) * 100000;
*
* The rounding is important since the measurement is sometimes going
* to be high or low by 0.025 MHz, depending on exactly how the clocks
* and counters interact. By rounding we get the exact answer for any
* CPU clock that is an even multiple of 0.1 MHz.

The current implementation allows the user to specify the desired CPU
clock value, in MHz, via an environment variable "cpuclk".
Four compile-time constants are used:
CONFIG_8xx_OSCLK - input quartz clock
CONFIG_SYS_8xx_CPUCLK_MIN - minimum allowed CPU clock
CONFIG_SYS_8xx_CPUCLK_MAX - maximum allowed CPU clock
CONFIG_8xx_CPUCLK_DEFAULT - default CPU clock value
If the "cpuclk" environment variable value is within the CPUCLK_MIN /
CPUCLK_MAX limits, the specified value is used. Otherwise, the
default CPU clock value is set.
Please make sure you understand what you are doing, and understand
the restrictions of your hardware (board, processor). For example,
ethernet will stop working for CPU clock frequencies below 25 MHz.
Please note that the new clock-handling code is enabled if
CONFIG_8xx_CPUCLK_DEFAULT is defined. Since this mechanism supports
only MPC866 and newer CPUs, this constant MUST NOT be defined for
MPC823/850/860/862 series. The clock generation algorithm for older
chips is different and has not been implemented yet. If you need it,
your patch is welcome.
