[PATCH v3 0/3] Enable DT support for AT91SAM9263EK
This is version 3 of a patchset to enable device tree support for AT91SAM9263EK. The patchset is made on top of previous patches posted that move reset code to the board files for at91 boards. (Which are already part of -next) On the quest towards getting so far several drivers was converted to support DT. These patches went in around august. There was also issues with mach-at91 calling code in the board directory (dependency in the wrong direction). This was fixed in "at91: move reset .." which is pending (already posted). I have failed to get the bootstrap mode to work. It stops somewhere - and I have not invested enough time to figure out where and why things goes wrong. bootstrap mode was also broken before these patches. No JTAG debugger available to help me. And then I have at91bootstrap that works so motivation was not too high. I do not think the NAND support works either. The device tree introduces some nand-controller stuff that is not supported by barebox (at least I assume so). And this part I did not look further into. Next step is to get a proprietary board up and running (which uses NOR flash). But I wanted this patchset out in the open first. Thanks for feedback so far - especially from Andrey. Sam v2 => v3 - Squashed commit introducing support for multi image with the commit to add DT support - Fixed init of smc v1 => v2 Based on feedback from Andrey (thanks!) Patches reworked and combined as a result of this - Included two patches that makes some general improvements to mach-at91. (Updated since the RFC versions sent yesterday) - Move irq_fixup, thus allowing us to call this from board code. This makes it possible to have less dependencies between board code and the processor specific files in mach-at91. - Simplified soc setup. With this change setup.c no longer requires that at least one of the processor specific files are built. - Create a minimal dts file, based on top of the dts file supplied from the kernel. - Utilise gpio-hog - to setup gpio for PHY. - Simpler Makefile logic in board Makefile It is now obvious that init.c is only used for bootstrap - Processor specific files in mach-at91 no longer used when DT is enabled - Use IS_ENABLED() when it makes code simpler Sam Ravnborg (3): arm: at91: move irq_fixup to header file arm: at91: simplify soc setup at91sam9263ek: enable DT support arch/arm/boards/at91sam9263ek/Makefile| 4 +- arch/arm/boards/at91sam9263ek/lowlevel_init.c | 17 +++-- arch/arm/boards/at91sam9263ek/of_init.c | 93 +++ arch/arm/configs/at91sam9263ek_defconfig | 10 ++- arch/arm/dts/Makefile | 2 +- arch/arm/dts/at91sam9263ek.dts| 48 ++ arch/arm/mach-at91/Kconfig| 30 ++--- arch/arm/mach-at91/Makefile | 6 +- arch/arm/mach-at91/at91rm9200.c | 10 +-- arch/arm/mach-at91/at91sam9260.c | 10 +-- arch/arm/mach-at91/at91sam9260_devices.c | 1 + arch/arm/mach-at91/at91sam9261.c | 10 +-- arch/arm/mach-at91/at91sam9261_devices.c | 1 + arch/arm/mach-at91/at91sam9263.c | 10 +-- arch/arm/mach-at91/at91sam9263_devices.c | 1 + arch/arm/mach-at91/at91sam9g45.c | 10 +-- arch/arm/mach-at91/at91sam9g45_devices.c | 1 + arch/arm/mach-at91/at91sam9n12.c | 10 +-- arch/arm/mach-at91/generic.h | 11 +++- arch/arm/mach-at91/include/mach/at91_rtt.h| 16 + arch/arm/mach-at91/irq_fixup.c| 22 --- arch/arm/mach-at91/sama5d3.c | 10 +-- arch/arm/mach-at91/sama5d4.c | 10 +-- arch/arm/mach-at91/setup.c| 26 ++-- arch/arm/mach-at91/soc.h | 76 -- images/Makefile.at91 | 4 ++ 26 files changed, 277 insertions(+), 172 deletions(-) ___ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
