Up to now the PCIe link status on Freescale PCIe controllers was only checked once at boot time. So hotplug did not work. With this patch the link status is checked on every config read. PCIe devices not present at boot time are found after doing 'echo 1 >/sys/bus/pci/rescan'. Signed-off-by:

Move to keeping the SoC registers that control and config the PCI controllers on FSL SoCs in the pci_controller struct. This allows us to not need to ioremap() the registers in multiple different places that use them. Signed-off-by: -

Config FSL_SOC does not depend on PPC_CLOCK anymore since the following commit got merged: 93abe8e4 (clk: add non CONFIG_HAVE_CLK routines) Config CPM does not use PPC_CLOCK either currently. So remove them. PPC_CLOCK also keeps Freescale PowerPC archtecture from supporting COMMON_CLK. Signed-off-by:

The e6500 core used on T4240 and B4860 SoCs from FSL implements MMUv2 of the Power Book-E Architecture. However there are some minor differences between it and other Book-E implementations. Add support to parse SPRN_TLB1PS for the variable page sizes supported. In the future this should be expanded for more page sizes supported on e6500 as well as other MMU features. This patch is based on code from Scott Wood. Signed-off-by: -

The T4240 utilizes a new PCIe controller block that has some minor programming model differences from previous versions. The major one that impacts initialization is how we determine the link state. On the 3.x controllers we have a memory mapped SoC register instead of a PCI config register that reports the link state. Signed-off-by:

We support DSCR (Data Stream Control Register) so we should make sure we set it in the FSCR (Facility Status & Control Register) incase some firmwares don't set it. If we don't set this, we'll take a facility unavailable exception when using the DSCR. Signed-off-by:

Currently we only set the FSCR (Facility Status and Control Register) when HV=1 but this feature is available when HV=0 also. This patch sets FSCR when HV=0. Also, we currently only set the FSCR on the master CPU. This patch also sets the FSCR on secondary CPUs. Signed-off-by:

Currently we use the link register to branch up high in the early MMU on syscall entry path. Unfortunately, this trashes the link stack as the address we are going to is not associated with the earlier mflr. This patch simply converts us to used the count register (volatile over syscalls anyway) instead. This is much better at predicting in this scenario and doesn't trash link stack causing a bunch of additional branch mispredicts later. Benchmarking this on POWER8 saves a bunch of cycles on Anton's null syscall benchmark here: http://ozlabs.org/~anton/junkcode/null_syscall.cSigned-off-by:
