I skip the deep-probe explanation here and instead refer to the detailed commit message of patch 5. Thanks a lot to Sascha and Ahmad for the review feedback :) Each patch has a own changelog so I dropped it from the cover letter. Patch 1: - Another fixes patch. In V1 this was part of patch 5. I seperate this patch to make it more clear and clean. Patche 2-4 - Deep probe preparation patche Patch 5: - The interesting part of this series. This patch implements the deep-probe mechanism and adds helpers to make your board deep-probe aware. Patch 6-7: - Adds STM32MP1 and i.MX architecture specific deep-probe code. For those architectures this means that we need to populate the memory-controller. Patch 8: - Convert the sabrelite board to use the deep_probe mechanism. This can be used as example for others :) Comments and testers are welcome, as always :) Regards, Marco Lucas Stach (1): of: base: move memory init from DT to initcall Marco Felsch (7): of: platform: Keep track of populated platform devices of: base: move clock init from of_probe() to barebox_register_of() initcall: add of_populate_initcall common: add initial barebox deep-probe support ARM: i.MX: esdctl: add deep-probe support ARM: stm32mp: ddrctrl: add deep-probe support ARM: boards: mx6-sabrelite: add deep-probe support .../boards/freescale-mx6-sabrelite/board.c | 24 +- arch/arm/mach-imx/esdctl.c | 13 +- arch/arm/mach-stm32mp/ddrctrl.c | 13 +- common/Makefile | 1 + common/deep-probe.c | 36 +++ drivers/base/driver.c | 11 +- drivers/clk/clk.c | 5 + drivers/i2c/i2c.c | 8 + drivers/of/base.c | 28 ++- drivers/of/platform.c | 216 +++++++++++++++--- drivers/regulator/core.c | 6 + drivers/reset/core.c | 4 + drivers/spi/spi.c | 2 + include/asm-generic/barebox.lds.h | 11 +- include/deep-probe.h | 26 +++ include/init.h | 10 +- include/of.h | 33 ++- 17 files changed, 392 insertions(+), 55 deletions(-) create mode 100644 common/deep-probe.c create mode 100644 include/deep-probe.h -- 2.20.1 _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
