This patch allow to override CONFIG_SYS_TCLK from board configuration
files. This is needed for the Network Space v2 which use a non standard
core clock frequency (166MHz instead of 200MHz for a 6281 SoC).
As a possible enhancement for 6281 and 6282 devices, TCLK could be
dynamically detected by checking the Sample at Reset register bit 21.
Additionally this patch fix a typo.

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.

boot_flash_type was totally unused. The other ones were actually constants, so

The reset sequence/configuration for ehci is highly board specific,
so this will be done in the source for the board, instead of
introducing several CONFIG_* which would be needed to make those

Use the same method of the Linux kernel to print the MX31 silicon version on

As exception among the i.MX processors, the i.MX31 has headers
without general names (mx31-regs.h, mx31.h instead of imx-regs.h and
clock.h). This requires several nasty #ifdef in the drivers to
include the correct header. The patch cleans up the driver and
renames the header files as for the other i.MX processors.

The patch add CONFIG_HW_WATCHDOG to be used
with the internal watchdog timer of the MX31
processor. Two function are exported for the
board maintainers:
mxc_hw_watchdog_enable
mxc_hw_watchdog_reset
The board maintainer can decide to use mxc_hw_watchdog_reset as
hw_watchdog_reset, or to implement his own function to reset
the watchdog.
The watchdog timer can be configured with CONFIG_SYS_WD_TIMER_SECS
(value in seconds). The MX31 allows values between 0.5
(CONFIG_SYS_WD_TIMER_SECS = 0) and 128 seconds.

For the calls to boot_relocate_fdt(), boot_get_cmdline(), and
boot_get_kbd(), the value of bootmem_base is always obtained by
calling getenv_bootm_low(). Since the value always comes from the
same source, the calling signature for those functions can be
simplified by making them call getenv_bootm_low() directly.
