There will be option with 16MB flash for the following boards:
* A20-OLinuXino-MICRO Rev.K
* A20-OLinuXino-LIME Rev.J
* A20-OLinuXino-LIME2 Rev.J
* A20-SOM-EVB Rev.E
The used flash chip is Winbond W25Q128FV, which is connected to
SPI0 port. Since this is optional feature, spi0 node is dissabled
by default. Also this option is incompatible with NAND flash, so
they shouldn't be enabled at the same time.
