* powerpc/8xxx: Refactor SRIO initialization into common codeKumar Gala2011-01-14-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Moved the SRIO init out of corenet_ds and into common code for 8xxx/QorIQ processors that have SRIO. We mimic what we do with PCIe controllers for SRIO. We utilize the fact that SRIO is over serdes to determine if its configured or not and thus can setup the LAWs needed for it dynamically. We additionally update the device tree (to remove the SRIO nodes) if the board doesn't have SRIO enabled. Introduced the following standard defines for board config.h: CONFIG_SYS_SRIO - Chip has SRIO or not CONFIG_SRIO1 - Board has SRIO 1 port available CONFIG_SRIO2 - Board has SRIO 2 port available (where 'n' is the port #) CONFIG_SYS_SRIOn_MEM_VIRT - virtual address in u-boot CONFIG_SYS_SRIOn_MEM_PHYS - physical address (for law setup) CONFIG_SYS_SRIOn_MEM_SIZE - size of window (for law setup) [ These mimic what we have for PCI and PCIe controllers ] Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Wolfgang Denk <wd@denx.de>
* 85xx: Add support for not releasing secondary cores via 'mp_holdoff'Aaron Sierra2010-10-20-3/+19
| | | | | | | | | | | | | Some OSes require that secondary cores not be initialized when they are booted (eg VxWorks). By default when U-Boot is compiled with the CONFIG_MP option all secondary cores are brought out of reset and held in spinloops. Setting the "mp_holdoff" environment variable to 'yes' or '1' will cause U-Boot to leave secondary cores in their default state.

* mpx85xx/fdt: Add cpu-release-addr for all coresMatthew McClintock2010-08-19-7/+8
| | | | | | | | We currently do not add a cpu-release-addr for core 0, this is needed when we want to reset core 0 and later restart it from Linux Signed-off-by: Matthew McClintock <msm@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* powerpc/85xx: Add support to initialize LIODN registers and portalsKumar Gala2010-07-26-0/+15
| | | | | | | | | | | On the new QorIQ/CoreNet based platforms we need to initialize the "portals" as access into the Data Path subystem as well as Logical IO Device Numbers (LIODN) that are used for the IOMMU (PAMU).

* powerpc/p4080: Add support for CPC(Corenet platform cache) on CoreNet platformsKumar Gala2010-07-26-0/+24
| | | | | | | | | | | | | The CoreNet style platforms can have a L3 cache that fronts the memory controllers. Enable that cache as well as add information into the device tree about it.

* powerpc/p4080: Add setting of clock-frequency for clockgen nodeKumar Gala2010-07-20-0/+5
| | | | | | | | On QorIQ CoreNet based devices we have a global clocking block. We want to keep track of SYSCLK frequency as it is what is used to derive all other frequencies in the SoC Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* powerpc/85xx: Use fdt_node_offset_by_compat_reg for clock-frequency updatesKumar Gala2010-07-20-8/+11
| | | | | | | Move to using fdt_node_offset_by_compat_reg to find the node offsets we want to update instead of using aliases. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* powerpc/8xxx: Add is_core_disabled to remove disabled cores from dtbKumar Gala2010-07-16-2/+2

* Move arch/ppc to arch/powerpcStefan Roese2010-04-21-0/+417
As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure. But "ppc" is kept as an alias for now, to not break compatibility with scripts using this name.
