* imx6: Remove kernel 4.14 supportHauke Mehrtens2020-03-121-525/+0
| | | | | | | | | This target was switched to kernel 4.19 more than 6 months ago in commit f342ffd300da ("treewide: kernel: bump some targets to 4.19") and now with kernel 5.4 support being added it gets harder to support kernel 4.14 in addition to kernel 4.19 and 5.4.

* kernel: disable CONFIG_USB_IMX21_HCD in default for kernel 4.14Yangbo Lu2019-02-171-1/+0
| | | | | | | | | | | CONFIG_USB_IMX21_HCD should be handled in generic config and module package. So moved it into generic config. This also fixed build issue (kernel config question) of layerscape armv8_32b since it also used ARCH_MXC. Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com> [Deactivate CONFIG_USB_IMX21_HCD also for kernel 4.19] Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* imx6: fix DMA transaction errorsKoen Vandeputte2018-11-061-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Following errors were seen in the past on imx6 when using serial: [ 22.617622] imx-uart 2020000.serial: DMA transaction error. [ 22.623228] imx-uart 2020000.serial: DMA transaction error. [ 22.628826] imx-uart 2020000.serial: DMA transaction error. [ 22.648951] imx-uart 2020000.serial: DMA transaction error. [ 22.654558] imx-uart 2020000.serial: DMA transaction error. [ 22.660156] imx-uart 2020000.serial: DMA transaction error. Which is the reason why DMA for the serial ports got disabled in commits: efb362cd93b0 ("imx6: disable dma on uart") 3b4241071dd4 ("imx6: disable UART dma") As indicated on mailinglist discussion, the cause seems to be the usage of very old SDMA firmware which is present in the soc: [ 0.624302] imx-sdma 20ec000.sdma: Direct firmware load for imx/sdma/sdma-imx6q.bin failed with error -2 [ 0.624318] imx-sdma 20ec000.sdma: Falling back to user helper [ 64.531607] imx-sdma 20ec000.sdma: external firmware not found, using ROM firmware This patch adds the new firmware binary. (2196 bytes) It is required to embed the binary into the kernel image, as it gets loaded very early in the boot process where the rootfs is not available yet: [ 0.622966] imx-sdma 20ec000.sdma: loaded firmware 3.3 Extended testing shows that the DMA errors are not seen anymore when using this newer firmware version.

* kernel: enable THIN_ARCHIVES by defaultSergey Ryazanov2018-05-221-1/+0
| | | | | | | | THIN_ARCHIVES option is enabled by default in the kernel configuration and no one target config disables it. So enable it by default and remove this symbol from target specific configs to keep them light. Signed-off-by: Sergey Ryazanov <ryazanov.s.a@gmail.com>
* kernel: enable FUTEX_PI by defaultSergey Ryazanov2018-05-221-1/+0
| | | | | | | | | New FUTEX_PI configuration symbol enabled if FUTEX and RT_MUTEX symbols are enabled. Both of these symbols are enabled by default in the generic config, so enable FUTEX_PI by default too to keep platform specific configs minimal.

* kernel: enable EXPORTFS by defaultSergey Ryazanov2018-05-221-1/+0
| | | | | | | | OVERLAY_FS config symbol selects EXPORTFS since 4.12 kernel, we have OVERLAY_FS enabled by default, so enable EXPORTFS in the generic config of 4.14 and remove this option from platform specific configs. Signed-off-by: Sergey Ryazanov <ryazanov.s.a@gmail.com>
* kernel: disable DRM_LIB_RANDOM by defaultSergey Ryazanov2018-05-221-1/+0
| | | | | | | DRM_LIB_RANDOM config symbol selected only by DRM_DEBUG_MM_SELFTEST which is disable by default, so disable DRM_LIB_RANDOM by default too. Signed-off-by: Sergey Ryazanov <ryazanov.s.a@gmail.com>
* kernel: disable DMA_{NOOP|VIRT}_OPS by defaultSergey Ryazanov2018-05-221-2/+0
| | | | | | | These options do not used by any supported arch, so disable them by default to make arch configs a bit more clean. Signed-off-by: Sergey Ryazanov <ryazanov.s.a@gmail.com>
* kernel: disable ARCH_WANTS_THP_SWAP by defaultSergey Ryazanov2018-05-221-1/+0
| | | | | | | | Only one arch (x86_64) enables this option. So disable ARCH_WANTS_THP_SWAP by default and remove referencies to it from all configs (except x86_64) to make them clean. Signed-off-by: Sergey Ryazanov <ryazanov.s.a@gmail.com>
