* at91: Merge SAMA5 subtargetsHauke Mehrtens2019-05-301-2/+3
| | | | | | | | | Instead of maintaining 3 very similar subtargets merge them into one. This does not use the Arm NEON extension any more, because the SAMA5D3 does not support NEON.

* at91: Clean up kernel configurationHauke Mehrtens2019-05-301-17/+1
| | | | | | | | This removes some settings which are normally set by the generic configuration and should not be changed. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Tested-by: Sandeep Sheriker <sandeepsheriker.mallikarjun@microchip.com>
* at91: Refresh kernel configurationHauke Mehrtens2019-05-301-50/+47
| | | | | | | | | | | The configuration of the sama5d4 subtarget was used as the default configuration and then the subtarget configurations were adapted. The resulting kernel configuration without any extra modules selected is still the same.

* kernel: Activate CONFIG_SYN_COOKIES for all targetsHauke Mehrtens2019-05-111-1/+0
| | | | | | | | | | Some targets deactivated CONFIG_SYN_COOKIES, for unknown reasons, use the default setting from the generic configuration which activates CONFIG_SYN_COOKIES. This should prevent SYN flooding. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* kernel: Deactivate CONFIG_COMPAT_BRKHauke Mehrtens2018-12-261-1/+0
| | | | | | | | | CONFIG_COMPAT_BRK disables the heap randomization which is only needed for very old and ancient user space applications, I am not aware that we run any of these, just deactivate this option for these targets to allow heap randomization.

* kernel: enable memory compactionFelix Fietkau2018-10-091-1/+0
| | | | | | | | | | | Compaction is the only memory management component to form high order (larger physically contiguous) memory blocks reliably. The page allocator relies on compaction heavily and the lack of the feature can lead to unexpected OOM killer invocations for high order memory requests. You shouldn't disable this option unless there really is a strong reason for it. Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Michal Hrusecky <michal.hrusecky@nic.cz>
* kernel: only optimized for size if small_flashMathias Kresin2018-07-121-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | Add a new config option to allow to select the default compile optimization level for the kernel. Select the optimization for size by default if the small_flash feature is set. Otherwise "Optimize for performance" is set. Add the small_flash feature flag to all (sub)targets which had the optimization for size in their default kernel config. Remove CC_OPTIMIZE_FOR_* symbols from all kernel configs to apply the new setting. Exceptions to the above are: - lantiq, where the optimization for size is only required for the xway_legacy subtarget but was set for the whole target - mediatek, ramips/mt7620 & ramips/mt76x8 where boards should have plenty of space and an optimization for size doesn't make much sense - rb532, which has 128MByte flash Signed-off-by: Mathias Kresin <dev@kresin.me>
* kernel: remove DEVMEM and DEVKMEM from target's configLuis Araneda2018-07-071-2/+0
| | | | | | | | | These options are handled by generic configuration Targets that need these options should select KERNEL_DEVMEM and/or KERNEL_DEVKMEM options on OpenWRT's config Signed-off-by: Luis Araneda <luaraneda@gmail.com>
* at91: cleanup kernel configurationsJo-Philipp Wich2018-05-111-53/+4
| | | | | | | | | | The subtarget configurations contained a lot of reduntant symbols, arbitrary overrides and symbols set to =m. Remove most of these redundant settings to shrink the subtarget configurations to a manageable size. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
