flash_olpcx2294_v2 package

[Sergei Gavrikov <sergei dot gavrikov at gmail dot com>]

Hello

This is flash v2 driver for Olimex LPC-X2294 boards on top of strata_v2
flash driver. Tested on Olimex LPC-H2294 board. Redboot's FIS works fine
with the driver.

SYNOPSYS

	ecosconfig remove flash_olpcx2294
	ecosconfig add strata_v2 flash_olpcx2294_v2 flash

RFC: I described and the bottom boot blocks in the driver. What is a
practic, to hide or show it? It seemed for me what I could describe
flash geometry and as 64 x 0x10000.
