[U-Boot] [PATCH v2 0/19] powerpc: Introduce device tree control and driver model
This series does a small amount of tweaking to support device tree control (CONFIG_OF_CONTROL) on PowerPC platforms. It also adds support for driver model. In both cases the main effort is to set things up correctly before calling board_init_f(). A new generic function, board_init_f_mem() is introduced. This does the various memory calculations in C code, since they are messy in assembler and every architecture should in fact be the same. A later series will adjust ARM and x86 to use this function. As an example, the Canyonlands boards are converted over to use device tree control and driver model for their serial console. It should be fairly straightforward to convert over other boards. Changes in v2: - Reduce reserved stack space for board_init_f_mem() to 64 bytes - Add SYS_MALLOC_F to Kconfig Simon Glass (15): Introduce board_init_f_mem() to handle early memory layout powerpc: Permit device tree control of U-Boot (CONFIG_OF_CONTROL) powerpc: ppc4xx: canyonlands: config: Tidy up CONFIGs and config.mk powerpc: ppc4xx: Move CANYONLANDS/GLACIER/ARCHES to Kconfig powerpc: ppc4xx: Add ramboot config for glacier powerpc: ppc4xx: canyonlands: Move to generic board powerpc: ppc4xx: dts: Bring in canyonlands device tree files powerpc: ppc4xx: Call board_init_f_mem() for generic board powerpc: ppc4xx: Add a gpio.h header file powerpc: ppc4xx: Allow the end of u-boot.bin to be found powerpc: ppc4xx: Use CONFIG_OF_CONTROL for canyonlands boards ppc: amcc: Omit unneeded ns16550 CONFIG if using driver model powerpc: Add serial driver for driver model dm: powerpc: ppc4xx: Move glacier to use driver model for serial powerpc: Add linkage.h file Stefan Roese (4): WIP: powerpc: ppc4xx: Somehow BSS is not cleared in RAMBOOT case powerpc: ppc4xx: Change from OF_SEPARATE to OF_EMBED powerpc: ppc4xx: Add defaults for DT based booting to really work powerpc: ppc4xx: Enable CONFIG_DISPLAY_BOARDINFO arch/Kconfig| 1 + arch/powerpc/cpu/ppc4xx/44x_spd_ddr2.c | 8 + arch/powerpc/cpu/ppc4xx/config.mk | 5 +- arch/powerpc/cpu/ppc4xx/cpu_init.c | 2 + arch/powerpc/cpu/ppc4xx/start.S | 18 +- arch/powerpc/cpu/ppc4xx/u-boot.lds | 8 +- arch/powerpc/dts/Makefile | 11 + arch/powerpc/dts/arches.dts | 339 arch/powerpc/dts/canyonlands.dts| 561 +++ arch/powerpc/dts/glacier.dts| 582 arch/powerpc/include/asm/arch-ppc4xx/gpio.h | 7 + arch/powerpc/include/asm/linkage.h | 7 + arch/powerpc/include/asm/ppc460ex_gt.h | 2 + arch/powerpc/lib/board.c| 3 + board/amcc/canyonlands/Kconfig | 36 ++ board/amcc/canyonlands/MAINTAINERS | 1 + board/amcc/canyonlands/config.mk| 2 - board/amcc/canyonlands/u-boot-ram.lds | 85 common/board_f.c| 18 + common/board_r.c| 8 +- configs/arches_defconfig| 5 +- configs/canyonlands_defconfig | 5 +- configs/glacier_defconfig | 5 +- configs/glacier_ramboot_defconfig | 8 + drivers/serial/Makefile | 1 + drivers/serial/serial_ppc.c | 40 ++ include/configs/amcc-common.h | 2 + include/configs/canyonlands.h | 38 +- 28 files changed, 1778 insertions(+), 30 deletions(-) create mode 100644 arch/powerpc/dts/Makefile create mode 100644 arch/powerpc/dts/arches.dts create mode 100644 arch/powerpc/dts/canyonlands.dts create mode 100644 arch/powerpc/dts/glacier.dts create mode 100644 arch/powerpc/include/asm/arch-ppc4xx/gpio.h create mode 100644 arch/powerpc/include/asm/linkage.h create mode 100644 board/amcc/canyonlands/u-boot-ram.lds create mode 100644 configs/glacier_ramboot_defconfig create mode 100644 drivers/serial/serial_ppc.c -- 2.2.0.rc0.207.ga3a616c ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
