[U-Boot-Users] global data pointer on arm
Hi,
I'm currently trying to replace armboot with u-boot-1.1.1 on a custom board with an epxa10 chip. While debugging, I discovered that the compiled code of getenv_r destroys the content of r8, which holds the global data pointer. Of course this makes u-boot fail. Is this a bug in u-boot or the toolchain? Or did I miss something else?
Regards, Andreas

Umm... of course I missed something: I shouldn't stop reading in the middle of the relevant gcc info page.
JFTR: in cpu/epxa/config.mk add '-ffixed-r8' to PLATFORM_RELFLAGS.
Soliloquizing, Andreas
