microblaze: Sane handling of missing timer/intc in device tree

2009-08-18T08:33:30+00:00

This code path doesn't test any returned pointers for NULL, leading to a bad
kernel page fault if there's no timer/intc found.

Slightly better is to BUG(), but even better still would be a printk beforehand.

microblaze: Makefile cleanup

2009-07-27T07:03:20+00:00

Reviewed the Makefile on request by Michal and this is the resulting changes.

o Use ':=' for assignmnet so we do not re-evaluate for each use
o Use $(shell echo xxx) to remove ""
o Replaced CFLAGS_KERNEL with KBUILD_CFLAGS
  The settings are equally relevant for modules and the linked kernel
o Dropped LDFLAGS_BLOB - it is no longer used
o Refactored assignmnets to libs-y and core-y
o Use MMU for the MMU specific extension. "MMUEXT" was hurting my eyes
  and I did not wanted it spread to m68k

For example reiserfs use this relocation type.

microblaze: Get module loading working

2009-07-27T07:03:17+00:00

New reloc type R_MICROBLAZE_32_PCREL_LO requires a null handler (no work to do).

Remove legacy hack for broken linker pre gcc-4.1.1, that required us to extract
an offset from the code, add it to the addend, then rewrite the instruction.

Fixup the invalid reloc type error output.

Boot tested with the xilinx_emaclite ethernet driver.

microblaze: remove sys_ipc

2009-07-27T07:03:16+00:00

The ipc system call is now unused in microblaze,
as the system call table points directly to the
indidual system calls for IPC.

microblaze: Support unaligned address for put/get_user macros

2009-07-27T07:03:15+00:00

This patch add support for cases where load/store instruction
in put/get_user macro gets unaligned pointer to data and this
address is not valid. I prevent all cases which can failed.
I had to disable first stage of unaligned handler which is used
only for noMMU kernel and the whole work is done when interrupt
is enabled.
You have enable HW support for detect unaligned access in Microblaze.

This patch fixed three LTP tests:
getpeername01, getsockname01, socketpair01
