2009-09-21microblaze: Improve checking mechanism for MSR instructionMichal Simek
It is more safe to use clear instead of msrset. We save some instructions too. Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-09-21microblaze: Add checking mechanism for MSR instructionMichal Simek
It was necessary to use fourth parameter(r8) in early_printk to show messages on console. Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-07-27microblaze: Clear print messages for DTB passing via r7Michal Simek
It is necessary to zeroed r7 when r7 points to bad dtb - this caused that we have correct messages about compiled-in dtb or passing via r7 Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-07-27microblaze: Not to clear r7 after copying DTB to kernelMichal Simek
I can't clear r7 because if I do it I lose information where DTB come from. Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-07-27microblaze: Final support for statically linked DTBJohn Williams
If r7 is zero at kernel boot, or does not point to a valid DTB, then we fall back to a DTB (assumed to be) linked statically in the kernel, instead of blindly copying bogus cruft into the kernel DTB memory region Signed-off-by: John Williams <john.williams@petalogix.com> Signed-off-by: Michal Simek <monstr@monstr.eu>
