Several source files need to be compiled and linked when one or more
config options are selected. To allow for easy selection in the
Makefiles yet to avoild multiple compilation (which costs build time)
and especially multiple linking (which causes errors), we use
"COBJS = $(sort COBJS-y)" which eliminates duplicates.

This "||" doesn't seem to work. Now using the idea suggest by Scott Wood
to combine both config options into one line. This even allows defining
both options and not generating the target object twice.

MC13783 is a multifunction IS with an SPI interface to the host. This
driver handles the RTC controller in this chip.

This patch add support for the STM M41T62 RTC. It is used and tested
on the AMCC Canyonlands 406EX platform.

This driver is based on the driver for the M41T11.  In the intended
application, the RTC will be powered by a large capacitor, rather than a
battery.  The driver therefore checks to see whether the RTC has lost
power.  The chip's OUT bit is normally reset from its power-up state.  If
the OUT bit is read as set, or if the date and time are not valid, then the
RTC is assumed to have lost power, and its date and time are reset to
1900-01-01 00:00:00.

Support for adjusting the speed of the clock to improve accuracy is
provided through an environment variable.

This change is in preparation for condtitionial compile support in the
build system.  By spliting them all into seperate lines now, subsequent
patches that change 'COBJS-y += ' into 'COBJS-$(CONFIG_<blah>) += ' will
be less invasive and easier to review

This patch adds support for the Xicor/Intersil X1205 RTC used on the
AMCC Makalu eval board. This driver is basically cloned from the Linux
driver version (2.6.23).

This patch also introduces the Linux bcd.h header for the BCD2BIN/
BIN2BCD conversions. In the future some of the other U-Boot RTC driver
should be converted to also use this header instead of implementing
their own local copy of these functions/macros.

Based on patch by Mike Frysinger, 20 Jun 2006

Modifications are based on the linux kernel approach and
support two use cases:

  1) Add O= to the make command line
  'make O=/tmp/build all'

  2) Set environement variable BUILD_DIR to point to the desired location
  'export BUILD_DIR=/tmp/build'
  'make'

The second approach can also be used with a MAKEALL script
'export BUILD_DIR=/tmp/build'
'./MAKEALL'

Command line 'O=' setting overrides BUILD_DIR environent variable.

When none of the above methods is used the local build is performed and
the object files are placed in the source directory.
