doc: cleanup - move board READMEs into respective board directories

Also drop a few files referring to no longer / not yet supported
boards.

+# Porting U-Boot onto RPXlite board
+# Written by Yoo. Jonghoon
+# E-Mail : yooth@ipone.co.kr
+# IP ONE Inc.
+
+# Since 2001. 1. 29
+
+# Shell : bash
+# Cross-compile tools : Montavista Hardhat
+# Debugging tools : Windriver VisionProbe (PowerPC BDM)
+# ppcboot ver. : ppcboot-0.8.1
+
+###############################################################
+#	1. Hardware setting
+###############################################################
+
+1.1. Board, BDM settings
+	Install board, BDM, connect each other
+
+1.2. Save Register value
+	Boot with board-on monitor program and save the
+	register values with BDM.
+
+1.3. Configure flash programmer
+	Check flash memory area in the memory map.
+	0xFFC00000 - 0xFFFFFFFF
+
+	Boot monitor program is at
+	0xFFF00000
+
+	You can program on-board flash memory with VisionClick
+	flash programmer. Set the target flash device as:
+
+	29DL800B
+
+	(?) The flash memory device in the board *is* 29LV800B,
+		but I cannot program it with '29LV800B' option.
+		(in VisionClick flash programming tools)
+		I don't know why...
+
+1.4. Save boot monitor program *IMPORTANT*
+	Upload boot monitor program from board to file.
+	boot monitor program starts at 0xFFF00000
+
+1.5. Test flash memory programming
+	Try to erase boot program in the flash memory,
+	and re-write them.
+	*WARNING* YOU MUST SAVE BOOT PROGRAM TO FILE
+		BEFORE ERASING FLASH

+#	2. U-Boot setting
+###############################################################
+
+2.1. Download U-Boot tarball at
+	ftp://ftp.denx.de
+	(The latest version is ppcboot-0.8.1.tar.bz2)
+
+	To extract the archive use the following syntax :
+	> bzip2 -cd ppcboot-0.8.1.tar.bz2 | tar xf -
+
+2.2. Add the following lines in '.profile'
+	export PATH=$PATH:/opt/hardhat/devkit/ppc/8xx/bin
+
+2.3. Make board specific config, for example:
+	> cd ppcboot-0.8.1
+	> make TQM860L_config
+
+	Now we can build ppcboot bin files.
+	After make all, you must see these files in your
+	ppcboot root directory.
+
+	ppcboot
+	ppcboot.bin
+	ppcboot.srec
+	ppcboot.map
+
+2.4. Make your own board directory into the
+	ppcboot-0.8.1/board
+	and make your board-specific files here.
+
+	For exmanple, tqm8xx files are composed of
+	.depend : Nothing
+	Makefile : To make config file
+	config.mk : Sets base address
+	flash.c : Flash memory control files
+	ppcboot.lds : linker(ld) script? (I don't know this yet)
+	tqm8xx.c : DRAM control and board check routines
+
+	And, add your board config lines in the
+	ppcboot-0.8.1/Makefile
+
+	Finally, add config_(your board).h file in the
+	ppcboot-0.8.1/include/
+
+	I've made board/rpxlite directory, and just copied
+	tqm8xx settings for now.
+
+	Rebuild ppcboot for rpxlite board:
+	> make rpxlite_config
+	> make
+
+###############################################################
+#	3. U-Boot porting
+###############################################################
+
+3.1. My RPXlite files are based on tqm8xx board files.
+	> cd board
+	> cp -r tqm8xx RPXLITE
+	> cd RPXLITE
+	> mv tqm8xx.c RPXLITE.c
+	> cd ../../include
+	> cp config_tqm8xx.h config_RPXLITE.h
+
+3.2. Modified files are:
+	board/RPXLITE/RPXLITE.c		/* DRAM-related routines */
+	board/RPXLITE/flash.c		/* flash-related routines */
+	board/RPXLITE/config.mk		/* set text base address */
+	arch/powerpc/cpu/mpc8xx/serial.c /* board specific register setting */
+	include/config_RPXLITE.h	/* board specific registers */
+
+	See 'reg_config.txt' for register values in detail.

+
+Use Flash Burner to finish the work:
+
+First, TFTP the U-Boot image file to RAM; For example,
+RPXlite_DW.bin to 0x400000
+Second, TFTP FLASH Burner to RAM; For example,
+0x100000
+Third, run the FLASH Burner and Program the U-Boot
+image into the correct location in FLASH.

+Well, sometimes network function of PlanetCore couldn't work when
+switching from U-Boot to PlanetCore. For example, you couldn't
+download a file from HOST PC via TFTP. Don't worry, just restart your
+HOST PC and everything would work as smooth as clockwork. I don't
+know the reason WHY:-)
