* overlays: add overlays for pi 400 and cm4Aaron Shaw2021-02-071-0/+2
| | | | | | | add overlays for pi 400 and cm4 Change-type: patch Signed-off-by: Aaron Shaw <aaron@balena.io>
* raspberrypi4-64: No need to force arm_64bit=1Paul Barker2021-01-211-2/+0
| | | | | | This workaround is no longer needed with recent firmware. Signed-off-by: Paul Barker <pbarker@konsulko.com>
* conf: Use unified u-boot config for 64-bit targetsPaul Barker2021-01-211-1/+1
| | | | | | | | The rpi_arm64 configuration supports both Raspberry Pi 3 & 4 in 64-bit mode. Switching to this config is a small step towards supporting a unified build for these targets. Signed-off-by: Paul Barker <pbarker@konsulko.com>
* linux-raspberrypi: Enable use of 'RPI_EXTRA_CONFIG += ...' in local.confMatt Spencer2021-01-191-1/+1
| | | | | | | | | | | Before this patch, use of RPI_EXTRA_CONFIG += in a local.conf would overwrite the needed 'arm_64bit=1' defined in the core recipes. The net result would be a system that did not boot. This patch fixes the assignment of 'arm_64bit=1' even if RPI_EXTRA_CONFIG has been set elsewhere. Signed-off-by: matthew@thespencers.me.uk
* conf/machine: add pci to MACHINE_FEATURES for Pi4Allen Wild2020-01-071-0/+1
| | | | | | | This pulls in the pciutils package (including `lspci`) via packagegroup-base. Signed-off-by: Allen Wild <allenwild93@gmail.com>
* raspberrypi*.conf: Remove vc4 configuration as we already default to itAndrei Gherzan2019-09-161-1/+0
| | | | | | | | | As of late[1], we defaulted to enabling vc4graphics in MACHINE_FEATURES. Let's cleanup the machine configurations as per this change. [1] https://github.com/agherzan/meta-raspberrypi/pull/417 Signed-off-by: Andrei Gherzan <andrei@gherzan.ro>
* raspberrypi4-64: Remove the 3G RAM limitationAndrei Gherzan2019-08-151-1/+1
| | | | | | | | | The PCIe bounce buffers were ported[1] in the kernel so we can remove this limitation now. [1] https://github.com/raspberrypi/linux/pull/3144 Signed-off-by: Andrei Gherzan <andrei@gherzan.ro>
* raspberrypi4-64.conf: Limit RAM to 3GAndrei Gherzan2019-07-251-1/+1
| | | | | | | | | | | | | | | The PCI controller on the Raspberry Pi 4 acts as a DMA controller and can only address the first 3Gb[1] of the memory space. On 32bit this was addressed by implementing bouncing buffers[2] but this currently has no support for arm64. In order to have working USB, as a workaround, we limit the ram to 3G. Fixes #446 [1] https://github.com/raspberrypi/linux/issues/3093 [2] https://github.com/raspberrypi/linux/blob/rpi-4.19.y/drivers/pci/controller/pcie-brcmstb-bounce.c Signed-off-by: Andrei Gherzan <andrei@gherzan.ro>
* raspberrypi*: Define ARMSTUB for all machinesAndrei Gherzan2019-07-191-0/+2

* raspberrypi4-64.conf: Remove memory limitationAndrei Gherzan2019-07-181-1/+1
| | | | | | | | We can do this because the kernel now includes a workaround for the DMA issue. https://github.com/raspberrypi/linux/pull/3080 Signed-off-by: Andrei Gherzan <andrei@gherzan.ro>
* raspberrypi4-64.conf: Uboot configuration and drop armstubAndrei Gherzan2019-07-161-2/+8
| | | | | | We drop armstub configuration because the new firmware includes them. Signed-off-by: Andrei Gherzan <andrei@gherzan.ro>
