lpc32xx: add support for board work_92105
Work_92105 from Work Microwave is an LPC3250-
based board with the following features:
- 64MB or 128MB 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
This board has SPL support, and uses the LPC32XX boot
image format.
