[U-Boot] [PATCH v2] README: Add an example of adding a new board.

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

Show the simple end result of adding an example board (BeagleBoard).

  based on dirk's earlier email, i'm emphasizing that this represents
only the *end result* of adding BeagleBoard support to U-Boot.
anything more involved than that wouldn't really belong in the README
and would more properly be described in, say, an ARM porting guide.

+A real-life example of adding a new board
+=========================================
+
+  As a working example of the end result of adding a new board,
+here's a list of files and directories that were added/changed to
+support the OMAP3-based BeagleBoard.  Note that these changes don't
+represent *how* this board was added, they represent only the
+end result.
+
+  First, the new BeagleBoard-related files:
+
+  ./board/ti/beagle/
+      beagle.c
+      beagle.h
+      config.mk
+      Makefile
+  ./include/configs/omap3_beagle.h
+
+Followed by eventual changes to some 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
