Additionaly mgcoge2ne board supprot was removed, because due

Current timer routines (arch/mips/lib/timer.c) are implemented assuming
that MIPS32 coprocessor (CP0) resources, Counter and Compare registers
in this case, are available.  But this doesn't always work.

We need to make sure that all MIPS-based systems don't necessarily use
CP0 counter/compare registers as time keeping resources.  And some MIPS
variant processors might come with different hardware specs with genuine
MIPS32 CP0 registers.

With this change, each $(CPU)/ directory can have its own timer code.

Although most IDE controller is designed to be connected to PCI bridge,
there are still some IDE controller support AHB interface for SoC design.

The driver implementation of these IDE-AHB controllers differ from other
IDE-PCI controller, some additional registers and commands access is required
during CMD/DATA I/O. Hence a configuration "CONFIG_IDE_AHB" in cmd_ide.c is
required to be defined to support these kinds of SoC controllers. Such as
Faraday's FTIDE020 series and Global Unichip's UINF-0301.

While looking to upgrade to zlib-1.2.5, the current mondo merge of
multiple files into a single was making things way more difficult
than it should have been.  Hard to pick out what has been changed
to port it to U-Boot, been removed as useless, and bug fixes added
after the fact.

So split the single file up into the original file names, and merge
non-essential changes back from the original tree (for some reason,
style in code in a bunch of places was changed to U-Boot style even
though this isn't "U-Boot" code).

The original build style is retained -- we have a single zlib.c that
includes all the other files, and that is the only file we compile.

Currently, some linker scripts are found by common code in config.mk.
Some are found using CONFIG_SYS_LDSCRIPT, but the code for that is
sometimes in arch config.mk and sometimes in board config.mk.  Some
are found using an arch-specific rule for looking in CPUDIR, etc.

Further, the powerpc config.mk rule relied on CONFIG_NAND_SPL
when it really wanted CONFIG_NAND_U_BOOT -- which covered up the fact
that not all NAND_U_BOOT builds actually wanted CPUDIR/u-boot-nand.lds.

Replace all of this -- except for a handful of boards that are actually
selecting a linker script in a unique way -- with centralized ldscript
finding.

If board code specifies LDSCRIPT, that will be used.
Otherwise, if CONFIG_SYS_LDSCRIPT is specified, that will be used.

If neither of these are specified, then the central config.mk will
check for the existence of the following, in order:

$(TOPDIR)/board/$(BOARDDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT)
$(TOPDIR)/$(CPUDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT)
$(TOPDIR)/board/$(BOARDDIR)/u-boot.lds
$(TOPDIR)/$(CPUDIR)/u-boot.lds

Some boards (sc3, cm5200, munices) provided their own u-boot.lds that
were dead code, because they were overridden by a CPUDIR u-boot.lds under
the old powerpc rules.  These boards' own u-boot.lds have bitrotted and
no longer work -- these lds files have been removed.

  - introduce "bootrunner" environment variable
    This allows to execute consecutive different commands
    specified in the list "subbootcmd". If one command fails
    the command serie will stop.
  - introduce environment variable "develop", "ramfs" and "release"
    Each variable is one way to boot our linux. "develop" is for
    development purpose and boots the SW via NFS. "release" is for
    booting the linux image from flash, "ramfs" allows to load an SW
    image via tftp into ram and executes from there
  - introduce "addmem" variable, this command adds the used memory
    for linux to the bootargs
  - introduce "addvar" variable, this command adress for the /var
    directory to the kernel command line
  - introduce "setramfspram" and "setrootfsaddr" these calculation
    were done if "ramfs" was used (only for debugging)
  - introduce "tftpramfs" used for "ramfs" to load the image into
    RAM (only for debugging)
