[U-Boot] [PATCH] README: Give an explicit example of adding a new board.

[Robert P. J. Day <rpjday@crashcourse.ca>]

Explicitly demonstrate an example (BeagleBoard) of what was
added/changed to support a new board.

Signed-off-by: Robert P. J. Day <rpjday@crashcourse.ca>

  obviously not critical, but it might be useful for readers to see
explicitly what constitutes adding support for a new board, file by
file.  your choice to apply it or not.  i *think* i got everything.

+A real-life example of adding a new board
+=========================================
+
+  As a working example of adding a new board, consider the files
+and directories that were added/changed to support the OMAP3-based
+BeagleBoard.
+
+  First, the new files:
+
+  ./board/ti/beagle/
+      beagle.c
+      beagle.h
+      config.mk
+      Makefile
+  ./include/configs/omap3_beagle.h
+
+Followed by changes to existing files:
+
+	Makefile
+	========
+
+  omap3_beagle_config :   unconfig
+        @$(MKCONFIG) $(@:_config=) arm arm_cortexa8 beagle ti omap3
+
+	MAKEALL
+	=======
+
+  LIST_ARM_CORTEX_A8="            \
+        devkit8000              \
+        omap3_beagle            \
+        omap3_overo             \
+        ...
+
+	include/asm-arm-types.h
+	=======================
+
+  #ifdef CONFIG_MACH_OMAP3_BEAGLE
+  # ifdef machine_arch_type
+  #  undef machine_arch_type
+  #  define machine_arch_type     __machine_arch_type
+  # else
+  #  define machine_arch_type     MACH_TYPE_OMAP3_BEAGLE
+  # endif
+  # define machine_is_omap3_beagle() (machine_arch_type == MACH_TYPE_OMAP3_BEAGLE)
+  #else
+  # define machine_is_omap3_beagle()      (0)
+  #endif
+
+	doc/README.omap3
+	================
+
+  Build
+  =====
+
+  * BeagleBoard:
+
+  make omap3_beagle_config
+  make
