+ * Programming the Hymod FPGAs
+ *
+ * The 8260 io port config table is set up so that the INIT pin is
+ * held Low (Open Drain output 0) - this will delay the automatic
+ * Power-On config until INIT is released (by making it an input).
+ *
+ * If the FPGA has been programmed before, then the assertion of PROGRAM
+ * will initiate configuration (i.e. it begins clearing the RAM).
+ *
+ * When the FPGA is ready to receive configuration data (either after
+ * releasing INIT after Power-On, or after asserting PROGRAM), it will
+ * pull INIT high.
+ *
+ * Notes from Paul Dunn:
+ *
+ *  1. program pin should be forced low for >= 300ns
+ *     (about 20 bus clock cycles minimum).
+ *
+ *  2. then wait for init to go high, which signals
+ *     that the FPGA has cleared its internal memory
+ *     and is ready to load
+ *
+ *  3. perform load writes of entire config file
+ *
+ *  4. wait for done to go high, which should be
+ *     within a few bus clock cycles. If done has not
+ *     gone high after reasonable period, then load
+ *     has not worked (wait several ms?)

+# global_env
+#
+# file used by Hymod boards to initialise the u-boot non-volatile
+# environment when u-boot is first run (it determines this by the
+# absence of the environment variable "global_env_loaded")
+#
+# format of this file is:
+#
+#	1. blank lines and lines beginning with '#' are ignored
+#	2. all other lines must have the form <name>=<value>
+#	3. if a percent appears anywhere, it is replaced like so:
+#
+#		%s	serial number of the main board (10 digit zero filled)
+#		%S	serial number of the main board (plain number)
+#		%%	a percentage character
+#		... otherwise the %x is discarded
+#
+# if first character in <name> is a dash ('-'), then an existing env var
+# will not be overwritten (the dash is removed). i.e. it is only set if
+# it does not exist
+#
+# if last character in <name> is a plus ('+'), then <value> will be appended
+# to any existing env var (the plus is ignored). Duplicates of <value> are
+# removed.
+#
+# similarly, if the last character in <name> is a minus ('-'), then any
+# occurences of <value> in the current value of <name> will removed (the
+# minus is ignored).
+#
+# leading and trailing whitespace is removed in both <name> and <value>
+# (after processing any initial or final plus/minus in <name>).
+#
+
+# MISCELLANEOUS PARAMETERS
+
+# version must always come first
+version=4
+
+# set the ip address based on the main board serial number
+ipaddr=192.168.1.%S
+serverip=192.168.1.254
+

+
+# setting this to "yes" forces the global_env file to be loaded and processed
+# if the current version is different to the version in the file
+always_check_env=no

+# BOOTING COMMANDS AND PARAMETERS

+ * AMI FS6377 Clock Generator configuration table

+ * the "fs6377_regs[]" table entries correspond to FS6377 registers

+ *
+ * the data is written to the FS6377 via the i2c bus using address in
+ * "fs6377_addr" (address is 7 bits - R/W bit not included).
+ *
+ * The fs6377 has four clock outputs: A, B, C and D.
+ *
+ * Outputs C and D can each provide two different clock outputs C1/D1 or
+ * C2/D2 depending on the state of the SEL_CD input which is connected to
+ * the MPC8260 I/O port pin PA11. PA11 output (SEL_CD input) low (or 0)
+ * selects C1/D1 and PA11 output (SEL_CD input) high (or 1) selects C2/D2.
+ *
+ * PA11 defaults to output low (or 0) in the i/o port config table above.
+ *
+ * Output A provides a 100MHz for the High Speed Serial chips. Output B
+ * provides a 3.6864MHz clock for more accurate asynchronous serial bit
+ * rates. Output C is routed to the mezzanine connector but is currently
+ * unused - both C1 and C2 are set to 16MHz. Output D is used by both the
+ * alt-input and display mezzanine boards for their video chips. The
+ * alt-input board requires a clock of 24.576MHz and this is available on
+ * D1 (PA11=SEL_CD=0). The display board requires a clock of 27MHz and this
+ * is available on D2 (PA11=SEL_CD=1).
+ *
+ * So the default is a clock suitable for the alt-input board. PA11 is toggled
+ * later in misc_init_r(), if a display board is detected.
