Hi Stefan,
So what should I do now? Should I revert to another #ifdef in the
variable declaration? Or is the current version ok?
I'm not too sure myself. What really tickles me, and what speaks
against using this attribute, is the fact that the unused attribute is

Hi Stefan,
This patch adds another build target for the AMCC Sequoia PPC440EPx
eval board. This RAM-booting version is targeted for boards without
NOR FLASH (NAND booting) which need a possibility to initially
program their NAND FLASH. Using a JTAG debugger (e.g. BDI2000/3000)
configured to
