1d259e4d68 ARM: legoev3: convert to driver model
This converts LEGO MINDSTORMS EV3 to the driver model. MMC, SERIAL, SPI
and SPI_FLASH are converted.

The device tree contains only the minimal nodes required by U-Boot
since the size of U-Boot is limited to 256K on this device.

1374d88bf3 ARM: legoev3: increase flash image sizes
This increases the kernel image to 4M and the rootfs image to 10M.

It is getting hard to get a kernel image to fit in 3M.

2ac07f75d1 arm: Add support for LEGO MINDSTORMS EV3
This is based on the davinci da850evm. It can boot from either the
on-board 16MB flash or from a microSD card. It also reads board
information from an I2C EEPROM.

The EV3 itself initally boots from write-protected EEPROM, so no
u-boot SPL is needed.
