* ARM: remove remaining occurences of CONFIG_MMU_EARLYSascha Hauer2023-10-231-2/+0
| | | | | | | CONFIG_MMU_EARLY has been removed. Remove the remaining occurences of this option. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: rpi: add Raspberry Pi 4 supportAhmad Fatoum2022-06-171-0/+5
| | | | | | | | | | | | | | | With basic driver support added in previous commits, add the boilerplate to have barebox-raspberry-pi.img usable as bootloader for the Raspberry Pi 4 in 64-Bit mode. Tested peripherals: - SD-Card - pinctrl - clocksource - mini-UART Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Link: https://lore.barebox.org/20220609055922.667016-19-a.fatoum@pengutronix.de Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: rpi: rpi3: disallow MMU_EARLY && 64BITAhmad Fatoum2022-06-171-0/+2
| | | | | | | | | | | | Early MMU setup in 64-bit Raspberry Pi 3 barebox hangs, while normal setup concludes normally. Until this is figured out, disallow build of 64-Bit Raspberry Pi 3 support while CONFIG_MMU_EARLY=y. This issue doesn't affect the Raspberry Pi 4.

* ARM: rpi: add Raspberry Pi 3 64-bit build supportAhmad Fatoum2022-06-171-4/+17
| | | | | | | | | | | Have the subarch select the needed symbols to display a 32-bit/64-bit menu and hide the boards that aren't capable of 64-bit when CONFIG_64BIT=y. Building for 64-bit throws some warning about mismatched type sizes, so fix those as well.

* ARM: rpi: switch to ARM_USE_COMPRESSED_DTBAhmad Fatoum2022-06-171-0/+1
| | | | | | | | | | We'll add a generic image containing multiple DTs in a follow-up commit, which would benefit from compressing the DTs. For uniformity, compress the existing DTs as well to save some kilobytes there.

* ARM: rpi: move debug UART Kconfig settingsSascha Hauer2019-03-061-20/+0
| | | | | | | | | | | | In contrast to other architectures, R.Pi debug UART config was placed under the "System Type" menu, not under the "Debugging -> low-level debugging port". This made this setting easy to miss when enabling low level debug mesages. While at it use the existing base address defines rather than defining them again in Kconfig.

* ARM: rpi: Add device tree for Compute Module 3.Tomaz Solc2019-02-191-0/+6

* ARM: rpi: switch to DT probe and multi-image buildLucas Stach2017-03-021-5/+4
| | | | | | | | This commit switches the RaspberryPi arch over to probe Barebox from the builtin DT and enables multi-image builds. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* arm: bcm283x: add rpi2 supportAlexander Aring2016-01-071-0/+9
| | | | | | | | This patch adds Raspberry Pi 2 support in barebox. The features should be the same like the current RPi status in barebox. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* bcm2835: introduce mach-bcm283xAlexander Aring2016-01-041-0/+16
This patch changes the most part of mach-bcm2835 to mach-bcm283x. This prepares to add RPi2 support which is a bcm2836. This patch changes the Kconfig entry namens to BCM283X for drivers only. These drivers should working the same in bcm2836. While updating defconfig I added LED support/trigger option.
