This affects 32-bit PCI target devices that blindly assert STOP on memory-write transactions, without detecting that the data beat being transferred is the last data beat of the transaction. It can cause a hang. PCI-X operation is not affected by this erratum. Workaround: Setting the bit MDS in the PCI Bus Function Register will disable the combining of crossing cacheline boundary requests into one burst transaction. Therefore, it can prevent the errata scenario from occurring. This errata exists in MPC8543, MPC8543E, MPC8545, MPC8545E, MPC8547, MPC8547E, MPC8548 and MPC8548E. Refer to PCI 5 in MPC8548 errata document.

Even though eLBC isn't found on ARM SoCs (the newer IFC is used instead), I don't want to expand the use of FSL_SOC for things other than functions exported by fsl_soc.c. In particular, it would be odd to add it to MTD_NAND_FSL_ELBC and then remove it from MTD_NAND_FSL_IFC. Removing artificial dependencies also helps get compile-test exposure via randconfig, allyesconfig, etc. Reported-by: Brian Norris Cc: Brian Norris Signed-off-by: Scott Wood diff --git a/arch/powerpc/Kconfig b/arch/powerpc/Kconfig index a630ac2..7268d32 100644 --- a/arch/powerpc/Kconfig +++ b/arch/powerpc/Kconfig @@ -797,7 +797,6 @@ config 4xx_SOC config FSL_LBC bool "Freescale Local Bus support" - depends on FSL_SOC help Enables reporting of errors from the Freescale local bus controller.
