[OLPC-devel] Olpcflash works from LB

[Mitch Bradley]

I verified that you can run olpcflash from the LinuxBIOS payload kernel, 
instead of booting up all the way to the real kernel.  As expected, it 
works regardless of whether LB is loaded from SPI or PLCC.

You have to get the image from somewhere else, of course.  I did it by 
first reading the existing SPI FLASH contents to a file, then writing 
them back.

In the process of testing this, I discovered that buildrom requires 
manual intervention to ensure that the latest version of olpcflash.c is 
used.  The details are in http://dev.laptop.org/ticket/66
