2009-12-14microblaze: Use lowest-common-denominator default CPU settingsJohn Williams1-6/+6
This will ensure that kernels built with no custom CPU settings will still boot OK on hardware that has additional CPU hardware instructions etc. Signed-off-by: John Williams <john.williams@petalogix.com> Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-12-14microblaze: Update default generic DTSMichal Simek1-3/+7
It is generated with longer compatible list Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-12-14microblaze: Enable asm optimization only for HW with barrel-shifterMichal Simek1-1/+1
Asm code uses barrel-shifter instruction that's why we have to protect cases when HW don't have it. Reported-by: John Linn <john.linn@xilinx.com> Signed-off-by: Michal Simek <monstr@monstr.eu>
2009-12-14microblaze: Remove the buggy ALLOW_EDIT_AUTO config optionJohn Williams2-28/+8
This was intended to allow manual override of CPU settings copied automatically to Kconfig.auto, however it's problematic for several reasons, but mostly: * If the defconfig doesn't have ALLOW_EDIT_AUTO=y, then it's impossible for that defconfig to iverride the values in the kernel source tree. This leads to very strange errors where the kernel is compiled with the wrong CPUFLAGS. Next patch in the series will back out the default in Kconfig.auto to baseline settings, so a kernel built with no default values will at least boot on any hardware, just not make use of additional CPU features.
