Oops... My mistake. I've replied without carefully reading your 
question...
Right answer (I hope): you dont need to erase dataflash. AFAIK, 
dataflash erasing is performed by driver when you write into dataflash.
So, for example, to download binary into c0042000 dataflash "virtual" 
address, you can use simple "cp" command, without issuing "erase" 
command first, like this:

loadb 21000000
<sending image 0x12345 bytes long by kermit>
cp.b 21000000 c0042000 12345
