Common kernel image for e300 and e500v2

2009-01-23 Thread Johns Daniel
Is it possible -- and prudent -- to use a single kernel binary image for two similar boards, one based on an e300 core and the other on an e500v2 core? I was surprised to see that the e500v2-targeted toolchain did build the kernel for the e300 board just fine. Don't know whether this will always

Thank you for that piece of info, Scott! May I expand the question one bit, and ask whether the user-mode binaries compiled for the e300 will generally work for the e500 -- or, vice versa? Is one choice safer than the other? I know for sure that we take a big hit on floating-point ops, but are
