+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
