2013-08-21powerpc: Convert some mftb/mftbu into mfsprScott Wood2-5/+8
Some CPUs (such as e500v1/v2) don't implement mftb and will take a trap. mfspr should work on everything that has a timebase, and is the preferred instruction according to ISA v2.06. Currently we get away with mftb on 85xx because the assembler converts it to mfspr due to -Wa,-me500. However, that flag has other effects that are undesireable for certain targets (e.g. lwsync is converted to sync), and is hostile to multiplatform kernels. Thus we would like to stop setting it for all e500-family builds. mftb/mftbu instances which are in 85xx code or common code are converted. Instances which will never run on 85xx are left alone.

2013-06-25powerpc: Add T4 LAC device tree binding & defsJoe Liccese2-0/+201
The Interlaken is a narrow, high speed channelized chip-to-chip interface. To facilitate interoperability between a data path device and a look-aside co-processor, the Interlaken Look-Aside protocol is defined for short transaction-related transfers. Although based on the Interlaken protocol, Interlaken Look-Aside is not directly compatible with Interlaken and can be considered a different operation mode. The Interlaken LA controller connects internal platform to Interlaken serial interface. It accepts LA command through software portals, which are system memory mapped 4KB spaces. The LA commands are then translated into the Interlaken control words and data words, which are sent on TX side to TCAM through SerDes lanes.

Add SDHC DMA channel description to the mpc512x device tree to enable slave channel requesting in the mxcmmc driver. mpc512x DMA engine doesn't support endianness conversion when reading/writing data from peripheral's FIFO, so we have to swap data buffers before each DMA write and after each DMA read transfer manually.

2013-02-13powerpc/85xx: fix various PCI node compatible stringsTimur Tabi3-8/+8
Fix and/or improve the compatible strings of the PCI device tree nodes for some Freescale SOCs. This fixes some issues and improves consistency among the SOCs. Specifically: 1) The P1022 has a v1 PCIe controller, so the compatible property should just say "fsl,mpc8548-pcie". U-Boot does not look for "fsl,p1022-pcie", so it wasn't fixing up the node. 2) The P4080 has a v2.1 PCIe controller, so add that version-specific string to the device tree. Update the kernel to also look for that string. Currently, the kernel looks for "fsl,p4080-pcie" specifically, but eventually that check should be deleted. 3) The P1010 device tree claims compatibility with v2.2 and v2.3, but that's redundant. No other device tree does this. Remove the v2.2 string. 4) The kernel looks for both "fsl,p1023-pcie" and "fsl,qoriq-pcie-v2.2", even though the P1023 device trees has always included both strings. Remove the search for "fsl,p1023-pcie". Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2013-02-13powerpc/85xx: describe the PAMU topology in the device treeTimur Tabi5-48/+378
The PAMU caches use the LIODNs to determine which cache lines hold the entries for the corresponding LIODs. The LIODNs must therefore be carefully assigned to avoid cache thrashing -- two active LIODs with LIODNs that put them in the same cache line. Currently, LIODNs are statically assigned by U-Boot, but this has limitations. LIODNs are assigned even for devices that may be disabled or unused by the kernel. Static assignments also do not allow for device drivers which may know which LIODs can be used simultaneously. In other words, we really should assign LIODNs dynamically in Linux. To do that, we need to describe the PAMU device and cache topologies in the device trees.

2013-02-13powerpc/85xx: add alternate dts file for sbc8548 boot via SODIMMPaul Gortmaker1-0/+115
By moving the two JP12 jumpers 90 degrees, and switching the setting of SW2.8, the sbc8548 can be configured to boot off the alternate 64MB SODIMM, which when populated with u-boot can be a handy recovery option, in case the u-boot in the 8MB soldered on flash gets corrupted. Here we add an alternate dts file to match that configuration. To better highlight the differences, the output from the u-boot "fli" command is shown for the normal configuration and then the alternate configuration.

2013-02-13powerpc/85xx: update sbc8548 flash information to match recent u-bootPaul Gortmaker1-19/+15
The original memory map for the sbc8548 had the 64MB SODIMM flash device misaligned by 8MB to allow a window of address space for the soldered on 8MB device -- i.e. start end CS<n> width Desc. ---------------------------------------------------------- fb80_0000 ff7f_ffff CS6 32 SODIMM flash (64MB) ff80_0000 ffff_ffff CS0 8 Boot flash (8MB) However, if we want to change the configuration so that it boots off the 64MB flash, it is in turn then aligned with a 64MB boundary, starting at fc00_0000 (and the 8MB @ fb80_0000 -> fbff_ffff). This makes for complicated updates, since what is the beginning of the physical device is 8MB into its address space in the default configuration shown above. This issue was fixed as of u-boot commit 3fd673cf363bc86ed42eff713d4 ("sbc8548: relocate 64MB user flash to sane boundary") -- in which the SODIMM was mapped to ec00_0000 (natively aligned under efff_ffff) and so when JP12/SW2.8 are switched, it will be a a simple 0xec --> 0xfc mapping between the two instances. Here we make the associated changes in the localbus flash memory map in the dts file: indicating the 64MB device starts at ec00_0000 and that the tail end of the 64MB device (last 2 sectors) can contain a bootloader image. The partitions for both flash devices get a clean-up; there were non-meaningful assignments in there that probably originated from the MPC8548CDS on which the file was based on. Now there is just the categorization of free space and bootloader images. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2013-02-13powerpc/85xx: split sbc8548 dts file into pre and post chunksPaul Gortmaker3-318/+351
Updates to u-boot allow this board to boot off of either the 8MB soldered on flash, or the 64MB SODIMM flash. This is achieved by changing JP12 and SW2.8 which in turn swaps which flash device appears on /CS0 and /CS6 respectively. Since the flash devices are not the same size, this also changes the MTD memory map layout on the local bus. Here we split the common chunks out into a pre and post include, so they can be reused by an upcoming "alternative boot" dts file; leaving only the local bus chunk behind. No content changes are made at this point - it is just purely the move to using include files.

2013-02-12powerpc/5200: Use the gpt* labels to simplify mpc5200 dts filesGrant Likely11-235/+70
The DTC labels feature allows a dts file to reference a node without having to reproduce the entire node hierarchy above it. We can use this to simplify the MPC5200 board dts files by referencing the gpt nodes by label.

2013-02-12powerpc/5200: Add Lite5200 on-board LEDs as devicesGrant Likely2-12/+36
The Lite5200 evaluation board has a number of debug LEDs that Linux doesn't know about yet. This change adds a gpio-leds stanza to the lite5200 device tree so that the correct driver can get hooked up. Also, make use of the dtc labels feature to reduce the number of source lines required to add the gpio-controller property to the general purpose timer nodes. In addition, the required #gpio-cells properties are added to the common mpc5200b dtsi include file so that each board doesn't need to add them explicitly. This still doesn't enable gpio mode, 'gpio-controller' is required for that, but it means less work needs to be done by board ports.
