[U-Boot] [PATCH] Fix MCF5235 SDRAM base address macro
by Steve deRosier 22 Jan '13

22 Jan '13

SDRAMC_DARCn_BA() macro worked fine when the BA is 0x00000000 even though the macro is incorrect. It causes the BA to be set incorrctly for other base addresses. This patch fixes the macro so that base addresses other than zero can be used with the MCF5235.

[U-Boot] [PATCH 0/7] Add support for NVIDIA Tegra114 SoC
by Tom Warren 22 Jan '13

22 Jan '13

This patch series adds basic (boot to cmd prompt) support for Tegra114. This is based on the Tegra30 SPL, which inits the AVP (ARM7TDMI boot proc) first, then control is passed to the CPU (A15 quad cluster). It is based on current u-boot-tegra/next. Future patches will add support/drivers for I2C, SPI, MMC, USB, etc. The Dalmore (E1611) T114 board is supported initially. Tom Warren (7): Tegra114: Add arch-tegra114 include files Tegra114: Add AVP (arm720t) files Tegra114: Add CPU (armv7) files Tegra114: Add common CPU (shared) files Tegra114: Dalmore: Add DT files Tegra114: Add generic Tegra114 build support Tegra114: Add/enable Dalmore build (T114 reference board) arch/arm/cpu/arm720t/tegra-common/cpu.c | 23 +- arch/arm/cpu/arm720t/tegra-common/cpu.h | 13 +- arch/arm/cpu/arm720t/tegra114/Makefile | 42 + arch/arm/cpu/arm720t/tegra114/config.mk | 19 + arch/arm/cpu/arm720t/tegra114/cpu.c | 328 ++++++ arch/arm/cpu/armv7/tegra114/Makefile | 40 + arch/arm/cpu/armv7/tegra114/config.mk | 19 + arch/arm/cpu/tegra-common/ap.c | 8 +- arch/arm/cpu/tegra-common/board.c | 23 +- arch/arm/cpu/tegra114-common/Makefile | 41 + arch/arm/cpu/tegra114-common/clock.c | 1150 ++++++++++++++++++++ arch/arm/cpu/tegra114-common/funcmux.c | 63 ++ arch/arm/cpu/tegra114-common/pinmux.c | 506 +++++++++ arch/arm/dts/tegra114.dtsi | 5 + arch/arm/include/asm/arch-tegra/clk_rst.h | 61 +- arch/arm/include/asm/arch-tegra/gp_padctrl.h | 1 + arch/arm/include/asm/arch-tegra/pmc.h | 12 + arch/arm/include/asm/arch-tegra/tegra.h | 3 +- arch/arm/include/asm/arch-tegra114/clock-tables.h | 402 +++++++ arch/arm/include/asm/arch-tegra114/clock.h | 24 + arch/arm/include/asm/arch-tegra114/flow.h | 35 + arch/arm/include/asm/arch-tegra114/funcmux.h | 31 + arch/arm/include/asm/arch-tegra114/gp_padctrl.h | 59 + arch/arm/include/asm/arch-tegra114/gpio.h | 304 ++++++ arch/arm/include/asm/arch-tegra114/hardware.h | 22 + arch/arm/include/asm/arch-tegra114/pinmux.h | 618 +++++++++++ arch/arm/include/asm/arch-tegra114/pmu.h | 23 + arch/arm/include/asm/arch-tegra114/spl.h | 22 + arch/arm/include/asm/arch-tegra114/tegra.h | 26 + board/nvidia/common/board.c | 2 +- board/nvidia/dalmore/Makefile | 44 + board/nvidia/dalmore/dalmore.c | 39 + board/nvidia/dalmore/pinmux-config-dalmore.h | 249 +++++ board/nvidia/dts/tegra114-dalmore.dts | 13 + boards.cfg | 1 + include/configs/dalmore.h | 50 + include/configs/tegra114-common.h | 89 ++ 37 files changed, 4360 insertions(+), 39 deletions(-) create mode 100644 arch/arm/cpu/arm720t/tegra114/Makefile create mode 100644 arch/arm/cpu/arm720t/tegra114/config.mk create mode 100644 arch/arm/cpu/arm720t/tegra114/cpu.c create mode 100644 arch/arm/cpu/armv7/tegra114/Makefile create mode 100644 arch/arm/cpu/armv7/tegra114/config.mk create mode 100644 arch/arm/cpu/tegra114-common/Makefile create mode 100644 arch/arm/cpu/tegra114-common/clock.c create mode 100644 arch/arm/cpu/tegra114-common/funcmux.c create mode 100644 arch/arm/cpu/tegra114-common/pinmux.c create mode 100644 arch/arm/dts/tegra114.dtsi create mode 100644 arch/arm/include/asm/arch-tegra114/clock-tables.h create mode 100644 arch/arm/include/asm/arch-tegra114/clock.h create mode 100644 arch/arm/include/asm/arch-tegra114/flow.h create mode 100644 arch/arm/include/asm/arch-tegra114/funcmux.h create mode 100644 arch/arm/include/asm/arch-tegra114/gp_padctrl.h create mode 100644 arch/arm/include/asm/arch-tegra114/gpio.h create mode 100644 arch/arm/include/asm/arch-tegra114/hardware.h create mode 100644 arch/arm/include/asm/arch-tegra114/pinmux.h create mode 100644 arch/arm/include/asm/arch-tegra114/pmu.h create mode 100644 arch/arm/include/asm/arch-tegra114/spl.h create mode 100644 arch/arm/include/asm/arch-tegra114/tegra.h create mode 100644 board/nvidia/dalmore/Makefile create mode 100644 board/nvidia/dalmore/dalmore.c create mode 100644 board/nvidia/dalmore/pinmux-config-dalmore.h create mode 100644 board/nvidia/dts/tegra114-dalmore.dts create mode 100644 include/configs/dalmore.h create mode 100644 include/configs/tegra114-common.h

[U-Boot] [PATCH] MIPS: start{, 64}.S: fill branch delay slots with NOP instructions
by Gabor Juhos 22 Jan '13

22 Jan '13

The romReserved and romExcHandle handlers are accessed by a branch instruction however the delay slots of those instructions are not filled. Because the start.S uses the 'noreorder' directive, the assembler will not fill the delay slots either, and leads to the following assembly code: 0000056c <romReserved>: 56c: 1000ffff b 56c <romReserved> 00000570 <romExcHandle>: 570: 1000ffff b 570 <romExcHandle> In the resulting code, the second branch instruction is placed into the delay slot of the first branch instruction, which is not allowed on the MIPS architecture.

[U-Boot] Custodians, Maintainers and old platforms
by Tom Rini 22 Jan '13

22 Jan '13

Hey all, (I had attempted to bcc this to all listed maintainer, but that upset Google greatly. I'll send this out manually instead later). I'd like to put this out here for custodians and maintainers to consider, especially in light of the device model work that's not just coming but has already started being posted. One of the keys to the success of U-Boot has been the number of platforms that are supported. But part of supporting platforms is needing people to volunteer to maintain them long term and help with testing changes and so forth. So first of all, I've just tagged v2012.10-rc1. Please give this at least a basic test on whatever platforms you're able to. Second, with this, my next branch is now open and I'd like to start it by asking that platforms that people wish to abandon be removed. With the device model, lots of code will need adjusting and while it's mechanical in ways, it still needs to be run-time tested. And it's changes that someone must do. I know others have suggested adding or better publicizing our to-remove file. But one of the advantages of git is that it's easy to bring platforms back, should someone later wish to bring it back. But this also requires the removal to be done cleanly. All of that said, I would like to stress that if you maintain a platform and you wish to help with the testing and perhaps even the conversion effort, no matter the age of the platform it would be welcome and appreciated. And finally, if everyone really wants to go another direction with old platforms, I'm open to discussion of course. I just want to miminize work done on platforms that aren't active and we don't know if they will come back. -- Tom
