Freescale P2020 CPU Freeze over PCIe abort signal

2010-10-17 Thread Eran Liberty
This should probably go to the Freescale support, as it feels like a hardware issue yet the end result is a very frozen Linux kernel so I post here first... I have a programmable FPGA PCIe device connected to a Freescale's P2020 PCIe port. As part of the bring-up tests, we are testing two faul

[PATCH] powerpc: sysdev: fix signedness bug

2010-10-17 Thread Vasiliy Kulikov
sram_params.sram_size and sram_params.sram_offset were unsigned. If get_cache_sram_size() or get_cache_sram_offset() returns error code then it is not seen to the caller. Made sram_size and sram_offset signed. Signed-off-by: Vasiliy Kulikov --- arch/powerpc/sysdev/fsl_85xx_l2ctlr.c |4 ++--
