It also > corrects a UARTD bit error in clk_rst.h, and adds rudimentary GPIO > support so that the UART on Seaboard can be used by U-Boot (UARTD& > SPIFLASH are muxed, and the default POR setting is for SPI access, so > GPIO_PI3 has to be driven low to enable serial console I/O over UARTD). > Harmony has no SPIFLASH, so the issue doesn't exist there. > > With these changes, I can write U-Boot to SPI on Seaboard and boot with > it to the U-Boot cmd prompt. This should also apply to loading from NAND > on Seaboard and Harmony - testing to follow. > > Changes in V2: > - Change 2nd patch's description to 'Add basic GPIO definitions' > - Add more descriptive comment for CPCON use in init_pllx > > Tom Warren (3): > arm: Tegra2: Add missing PLLX init > arm: Tegra2: GPIO: Add basic GPIO definitions > arm: Tegra2: Move clk/mux init to board_early_init_f, add GPIO init > > arch/arm/cpu/armv7/tegra2/ap20.c | 29 ++++++++++++++ > arch/arm/include/asm/arch-tegra2/clk_rst.h | 6 ++- > arch/arm/include/asm/arch-tegra2/gpio.h | 59 ++++++++++++++++++++++++++++ > arch/arm/include/asm/arch-tegra2/tegra2.h | 1 + > board/nvidia/common/board.c | 32 ++++++++++----- > board/nvidia/common/board.h | 4 ++ > board/nvidia/harmony/Makefile | 1 + > board/nvidia/harmony/harmony.c | 34 ++++++++++++++++ > board/nvidia/seaboard/Makefile | 1 + > board/nvidia/seaboard/seaboard.c | 52 ++++++++++++++++++++++++ > 10 files changed, 206 insertions(+), 13 deletions(-) > create mode 100644 arch/arm/include/asm/arch-tegra2/gpio.h > create mode 100644 board/nvidia/harmony/harmony.c > create mode 100644 board/nvidia/seaboard/seaboard.c Applied to u-boot-arm, thanks.
