The MCR3000 board is equipped with an AM29LV160DB boot flash which is organised as follows: - One 16kb block - Two 8kb block - One 32kb block - Thirty one 64kb blocks
At the time being, u-boot is a single piece occupying the 320 first kbytes, then the environment is stored in the following 64kb block
The environment being quite tiny, we save one 64kb block by embedding the environment in the first 8kb block.
