+# 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
+#
+# no whitespace is removed in either <name> or <value>
+#
+# if first character in <name> is a dash ('-'), then an existing env var
+# will not be overwritten (the dash is removed).
+#
+# if last character in <name> is a plus ('+'), then <value> will be appended
+# to any existing env var (the plus is removed). Duplicates of <value> are
+# removed.

+U-Boot for a Musenki M-3/M-1 board
+---------------------------
+
+Musenki M-1 and M-3 have two banks of flash of 4MB or 8MB each.
+
+In board's notation, bank 0 is the one at the address of 0xFF800000
+and bank 1 is the one at the address of 0xFF000000.
+
+On power-up the processor jumps to the address of 0xFFF00100, the last
+megabyte of the bank 0 of flash.
+
+Thus, U-Boot is configured to reside in flash starting at the address of
+0xFFF00000. The environment space is located in flash separately from
+U-Boot, at the address of 0xFF800000.
+
+There is a Davicom 9102A on-board, but I don't have it working yet.

+Hi,
+
+so this is the port to the Embedded Planet RPX Super Board.
+
+ATTENTION
+This code is only tested on the AY-Version, which is an early release with some
+hardware bugs. The main problem is that this board uses the default Hard Reset
+Configuration Word and not the 4 bytes located at start of FLASH because at
+0xFE000000 is no FLASH. The FLASH consists out of 4 chips each 16bits wide. Be
+carefull, the bytes are swapped. So DQ0-7 is the high byte, DQ8-15 ist the low
+byte.
+
+The icache can only manually be enabled after reset.
+The FLASH and main SDRAM is working with icache enabled.
+The local SDRAM can only be used as data memory when icache is enabled.
+If U-Boot runs in local SDRAM, TFTP does not work.
+The functions in mii_phy.c are all working. Call mii_phy_discover() out of
+eth_init() and solve the linker error.
+I2C, RTC/NVRAM and PCMCIA are not working yet.
+
+TODO
+The 32MB local SDRAM is working but not shown in the startup messages of
+U-Boot. If you locate U-Boot or any other program to this area it won't run.
+Turning the ichache off does not solve this problem.
+
+As I won't buy another RPX Super there might be some little work to do for you
+getting this U-Boot port running on the final board.
