These boards use an embedded environment, which is not supported by the
generic arch/powerpc/cpu/ppc4xx/u-boot.lds script.

The breakage was introduced by commit 2cd95a25 "ppc4xx: Remove board
specific linker scripts from most PPC4xx boards"

As we try to get rid of board specific config.mk files we must
provide a way for board specific settings of the LDSCRIPT variable
(path to the linker script) where needed.

We now implement the following hierarchy:

- Highest priority has a "#define CONFIG_SYS_LDCONFIG" in the board
  config file.
- If CONFIG_SYS_LDCONFIG is not set, and the system is booting from
  NAND (CONFIG_NAND_SPL is set), then a board specific linker
  script board/$(BOARDDIR)/u-boot-nand.lds gets used.
- If we are not booting from NAND, we test if a processor specific
  linker script arch/powerpc/cpu/$(CPU)/u-boot.lds exists; if so we
  use that.
- As default, arch/powerpc/config.mk gets used.

So far, only the BAB7xx board would call the initialise_w83c553f()
function for the WINBOND 83C553 chip, even though some other boards
(HIDDEN_DRAGON, Sandpoint8240, Sandpoint8245) enabled it in their
board configuration.  These boards were also missing other config
settings needed for that, which resulted in build errors like this:

drivers/pci/libpci.o:(.got2+0x84): undefined reference to `ide_bus_offset'

Switch arch/powerpc/lib/board.c to call initialise_w83c553f() not on a
per-board base, but when a WINBOND_83C553 in enabled in a
configuration (like BAB7xx), and disable it in the boards that had
this set so far.

This patch fixes a problem noticed on lwmon5 (PPC440EPx) using the
common EHCI driver, when "usb reset" is issued multiple times.
Upon the 2nd (and further) "usb reset" command, the command fails
with the following messages:

=> usb reset
(Re)start USB...
USB:   Register 1111 NbrPorts 1
USB EHCI 1.00

       scanning bus for storage devices... 2 Storage Device(s) found
=> usb reset
(Re)start USB...
USB:   EHCI fail to reset
Error, couldn't init Lowlevel part

This patch fixes this problem. Now "usb reset" can be called multiple
times.

The partial linking patch changes how objects are specified to the linker
and breaks boards with an embedded environment.  So we need to tweak the
list of objects we specify via the linker script that go in the gap before
the embedded env to work with this new behavior.  This fixes linker errors
for all the boards in question.

The TI DA850/OMAP-L138/AM18x EVM can be populated with devices
having different maximum allowed CPU clock rating.

The maximum clock the chip can support can only be determined from
the label on the package (not software readable).

Introduce a method to pass the maximum allowed clock rate information
to kernel using ATAG_REVISION. The kernel uses this information to
determine the maximum cpu clock rate reachable using cpufreq.

Note that U-Boot itself does not set the CPU clock rate. The CPU
clock is setup by a primary bootloader ("UBL"). The rate setup by
UBL could be different from the maximum clock rate supported by the
device.

Having a loop with a counter is no timing guarentee for timing
accuracy or compiler optimizations. For e.g. the same loop counter
which runs when the MPU is running at 600MHz will timeout in around
half the time when running at 1GHz. or the example where GCC 4.5
compiles with different optimization compared to GCC 4.4. use timer
to keep track of time elapse and we use an emperical number - 1sec
for a worst case timeout.  This should never happen, and is adequate
imaginary condition for us to fail with timeout.
