Switch to generic board so that this board will not be broken/removed.

I realized that with v2014.10 u-boot is not starting up on
ppc4xx boards with CONFIG_SYS_GENERIC_BOARD set.
I bisected it down to this:
d54d7eb support blackfin board initialization in generic board_f
With
d29437a ppc: Make ppc4xx ready for CONFIG_SYS_GENERIC_BOARD
I set gd to a defined value for ppc4xx in cpu_init_f().
I did not realize that the gd struct has also to be memset()
to zero at this point.
But at least commit d54d7eb assumes it is:

}

This might also be an issue on other architectures, so maintainers should
check.

This board has been orphaned for more than 6 months.
It is the last board defining CONFIG_APM821XX.
The code inside #ifdef CONFIG_APM821XX should be removed too.

The generic board infrastructure assumes that gd is set by
arch code.

This patch removes support for the APM 405CR CPU.
This CPU is EOL and no board uses this chip.

APM errata CHIP_21 for the 405EX/EXr (from the rev 1.09 document dated
4/27/11) states that rev D processors may wake up with the wrong feature
set. This patch implements the APM-proposed workaround.
To enable this patch for your board, add the appropriate define for your
CPU to your board header file. See kilauea.h for more information. The
following variants are supported:
#define CONFIG_SYS_4xx_CHIP_21_405EX_NO_SECURITY
#define CONFIG_SYS_4xx_CHIP_21_405EX_SECURITY
#define CONFIG_SYS_4xx_CHIP_21_405EXr_NO_SECURITY
#define CONFIG_SYS_4xx_CHIP_21_405EXr_SECURITY
Please note that if you select the wrong define, your board will not
boot, and JTAG will be required to recover.
Tested on custom boards using:
CONFIG_SYS_4xx_CHIP_21_405EX_NO_SECURITY <sfalco@harris.com>

APM821XX is a new line of SoCs which are derivatives of
PPC44X family of processors. This patch adds support of CPU, cache,
tlb, 32k ocm, bootstraps, PLB and AHB bus.

This cleanup is done by creating header files for all SoC versions and
moving the SoC specific defines into these special headers. This way the
common header ppc405.h and ppc440.h can be cleaned up finally.
As a part from this cleanup, the GPIO definitions for PPC405EP are
corrected. The high and low parts of the registers (for example
CONFIG_SYS_GPIO0_OSRL vs. CONFIG_SYS_GPIO0_OSRH) have been defined in
the wrong order. This patch now fixes this issue by switching these
xxxH and xxxL values. This brings the GPIO 405EP port in sync with all
other PPC4xx ports.

This patch starts a bit PPC4xx header cleanup. First patch mostly
touches PPC440 files. A later patch will touch the PPC405 files as well.

This patch moves some ppc4xx related headers from the common include
directory (include/) to the powerpc specific one
(arch/powerpc/include/asm/). This way to common include directory is not
so cluttered with files.

This patch fixes a bug in reconfigure_pll(), where the detection of
the current bootstrap option is wrong. The ICS bits where incorrectly
shifted. This bug was found on the lwmon5 board, which uses bootstrap
option H (I2C bootstrap EEPROM).
Additionally a bit of code was moved into the if statement, since its
only used after later on. No need to run this code all the time.
Also, a few empty lines are added to make the code better readable.

This patch enables booting with option E on the PPC460EX/EXr/GT.
When booting with Option E, the PLL is in bypass, CPR0_PLLC[ENG]=0.
The Software Boot Configuration Procedure is needed to engage the
PLL and perform a chip reset.

As discussed on the list, move "arch/ppc" to "arch/powerpc" to
better match the Linux directory structure.
Please note that this patch also changes the "ppc" target in
MAKEALL to "powerpc" to match this new infrastructure. But "ppc"
is kept as an alias for now, to not break compatibility with
scripts using this name.
