-Work_92105 from Work Microwave is an LPC3250- based board with the
-following features:
-
-    - 64MB SDR DRAM
-    - 1 GB SLC NAND, managed through MLC controller.
-    - Ethernet
-    - Ethernet + PHY SMSC8710
-    - I2C:
-      - EEPROM (24M01-compatible)
-      - RTC (DS1374-compatible)
-      - Temperature sensor (DS620)
-      - DACs (2 x MAX518)
-    - SPI (through SSP interface)
-      - Port expander MAX6957
-    - LCD display (HD44780-compatible), controlled
-      through the port expander and DACs
-
-Standard SPL and U-Boot binaries
---------------------------------
-
-The default 'make' (or the 'make all') command will produce the
-following files:
-
-1. spl/u-boot-spl.bin	SPL, intended to run from SRAM at address 0.
-			This file can be loaded in SRAM through a JTAG
-			debugger or through the LPC32XX Service Boot
-			mechanism.
-
-2. u-boot.bin		The raw U-Boot image, which can be loaded in
-			DDR through a JTAG debugger (for instance by
-			breaking SPL after DDR init), or by a running
-			U-Boot through e.g. 'loady' or 'tftp' and then
-			executed with 'go'.
-
-3. u-boot.img		A U-Boot image with a mkimage header prepended.
-			SPL assumes (even when loaded through JTAG or
-			Service Boot) that such an image will be found
-			at offset 0x00040000 in NAND.
-
-NAND cold-boot binaries
------------------------
-
-The board can boot entirely from power-on with only SPL and U-Boot in
-NAND. The LPC32XX-specific 'make lpc32xx-full.bin' command will produce
-(in addition to spl/u-boot-spl.bin and u-boot.img if they were not made
-already) the following files:
-
-4. lpc32xx-spl.img	spl/u-boot-spl.bin, with a LPC32XX boot header
-			prepended. This header is required for the ROM
-			code to load SPL into SRAM and branch into it.
-			The content of this file is expected to reside
-			in NAND at addresses 0x00000000 and 0x00020000
-			(two copies).
-
-5. lpc32xx-boot-0.bin	lpc32xx-spl.img, padded with 0xFF bytes to a
-			size of 0x20000 bytes. This file covers exactly
-			the reserved area for the first bootloader copy
-			in NAND.
-
-6. lpc32xx-boot-1.bin	Same as lpc32xx-boot-0.bin. This is intended to
-			be used as the second bootloader copy.
-
-7. lpc32xx-full.bin	lpc32xx-boot-0.bin, lpc32xx-boot-1.bin and
-			u-boot.img concatenated. This file represents
-			the content of whole bootloader as present in
-			NAND at offset 00x00000000.
-
-Flashing instructions
----------------------
-
-The following assumes a working U-Boot on the target, with the ability
-to load files into DDR.
-
-To update the whole bootloader:
-
-	nand erase 0x00000000 0x80000
-	(load lpc32xx-full.bin at location $loadaddr)
-	nand write $loadaddr 0x00000000 $filesize
-
-To update SPL only (note the double nand write) :
-
-	nand erase 0x00000000 0x40000
-	(load lpc32xx-spl.img or lpc32xx-boot-N.bin at location $loadaddr)
-	nand write $loadaddr 0x00000000 $filesize
-	nand write $loadaddr 0x00020000 $filesize
-
-To update U-Boot only:
-
-	nand erase 0x00040000 0x40000
-	(load u-boot.img at location $loadaddr)
-	nand write $loadaddr 0x00040000 $filesize
