[U-Boot] Question related to flash organisation

On my powerpc 8xx board, I have 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, I would like to store it in one of the first small blocks. Is that feasible to have the startup .text stuff in the first 16k block, then a hole for the environment then the rest of .text after ?
