* linux/xilinx-kmeta: Collapse xilinx-* kmeta directories into oneNathan Rossi2017-10-1811-178/+0
| | | | | | | | | | | Collapse the existing xilinx-* kmeta directories into a single kmeta directory. At the same time remove all linux-xlnx specific kmeta, it is no longer required as linux-xlnx is using defconfigs as baseline kernel configuration.

* linux/config: Rework kmeta based on kernel-cache mergeNathan Rossi2017-10-1821-364/+11
| | | | | | | | | | | | | | | | A large portion of the kmeta in xilinx-common and xilinx-machine was upstreamed into the linux-yocto kernel-cache and is no longer needed in the meta-xilinx layer. This change removes any fragments that are in the yocto-kernel-cache, and reworks remaining configs for use with linux-yocto. Compatibly with linux-xlnx is dropped due to favouring defconfigs. This includes Zynq and MicroBlaze machine configs (excluding kc705 and Zybo Linux-BD BSP), board common bsp/ fragments and a number of feature fragments that are already available in the yocto kernel cache.

* linux/config: Add "CONFIG_USB_ULPI" for zynq7Nathan Rossi2017-02-011-0/+1
| | | | | | | Some boards use USB PHYs that need to be communicated with via ULPI. Enable CONFIG_USB_ULPI. Signed-off-by: Nathan Rossi <nathan@nathanrossi.com>
* linux-yocto_4.8: Resolve CONFIG_DEBUG_RODATA for ZynqNathan Rossi2016-12-211-3/+0
| | | | | | | | | | | | | | | This patch resolves a previous commit (ea4ca65aaf) which only mitigated the issue caused due to CONFIG_DEBUG_RODATA for Zynq. This issue has been properly fixed in the next version of the kernel (v4.10) and this change backports the patch to the v4.8 kernel for linux-yocto(-tiny). Additionally this change removes the forced disabling of CONFIG_DEBUG_RODATA allowing for Zynq platforms to use the feature without issue. Signed-off-by: Nathan Rossi <nathan@nathanrossi.com>
* linux/config: Update and improve config fragmentsNathan Rossi2016-11-1910-7/+66
| | | | | | | | | | | | Update and add new config fragments to enable newer features that are now in the newer kernels (e.g. Zynq and ZynqMP drivers/features). This update also attempts to cover ZynqMP configuration that is normally provided by the ZynqMP defconfig in linux-xlnx, this allows for better consistency between the Zynq/ZynqMP/MicroBlaze configuration for linux-xlnx as well as enabling better configuration setup for the linux-yocto* kernels.

* linux/config: For Zynq hard disable CONFIG_DEBUG_RODATANathan Rossi2016-11-111-0/+3
| | | | | | | | | | | | CONFIG_DEBUG_RODATA was switched to default yes in v4.6+ kernels. Whilst the feature works correctly it causes changes with how the kernel .head.text and .text sections are padded which allows for memory below 0x80000 (512KB) to be non-reserved and used as memory for DMA allocations which do not work on Zynq due to devices not being allowed to access DDR below 0x80000. Disabling CONFIG_DEBUG_RODATA prevents the padding between .head.text/.text. Signed-off-by: Nathan Rossi <nathan@nathanrossi.com>
* linux-yocto-tiny: Add support for building linux-yocto-tiny 4.8Nathan Rossi2016-10-293-0/+33
| | | | | | | This adds support for building linux-yocto-tiny 4.8 kernel for the 3 main meta-xilinx architectures. Signed-off-by: Nathan Rossi <nathan@nathanrossi.com>
* linux/config: Add specific dependencies that are defaulted to yesNathan Rossi2016-10-298-1/+23
| | | | | | | | Add specific config options that are normally defaulted to yes when the kernel is configured with defaulting to yes. This allows for kernels that default no to be correctly configured. Signed-off-by: Nathan Rossi <nathan@nathanrossi.com>
* linux/config: Clean up soc/microblaze.cfgNathan Rossi2016-09-281-4/+1
| | | | | | | | | * CONFIG_SERIAL_OF_PLATFORM is already configured with serial drivers in soc/drivers/xilinx.cfg * Use the syntax "# CONFIG_FTRACE is not set" so that it when the kernel config check is run it matches the value set in the .config Signed-off-by: Nathan Rossi <nathan@nathanrossi.com>

* board-common.cfg: Disable 4K sectors on QSPI NOR flashMike Looijmans2016-07-311-0/+1
| | | | | | | | | | | | The 4K sector support makes erasing much slower and prevents using wear-levelling filesystems like UBI, which needs erase sectors to be at least 16k in size. Until this situation has been properly resolved in the kernel, disable the setting. For a discussion on the topic, and the reason the config exists, see: https://patchwork.ozlabs.org/patch/380565/ Signed-off-by: Mike Looijmans <mike.looijmans@topic.nl> Signed-off-by: Nathan Rossi <nathan@nathanrossi.com>

* linux/configs: Enable SERIAL_OF_PLATFORM to fix up dt parsingNathan Rossi2016-01-201-0/+1
| | | | | | | | SERIAL_OF_PLATFORM needs to be set in order for the serial 8250 driver to parse and probe device tree configuration for 8250 nodes. This is needed so that the uart 16550 instances are probed correctly. Signed-off-by: Nathan Rossi <nathan@nathanrossi.com>

* linux/configs: Split PCIe drivers off from zynq7 config fragmentNathan Rossi2015-12-213-3/+12
| | | | | | | | | | | | | | | The PCIe drivers for the Xilinx AXI PCIe bridge are only available on Zynq targets when have the soft core loaded, for all other targets this driver is not required. To optimized the kernel for general use make the PCIe driver a seperate fragment which can be enabled by adding 'bsp/xilinx/soc/drivers/xilinx-pcie.scc' to KERNEL_FEATURES. Also add to the config fragment the required kernel options to enable PCI. Signed-off-by: Nathan Rossi <nathan@nathanrossi.com>
