[U-Boot] [PATCH v3] arm : Atmel : add at91sam9x5ek board support
Add at91sam9x5ek board support, this board support the following SoCs AT91SAM9G15, AT91SAM9G25, AT91SAM9G35, AT91SAM9X25, AT91SAM9X35
Using at91sam9x5ek_nandflash to configure for the board Now only supports NAND with software ECC boot up
Signed-off-by: Bo Shen voice.shen@atmel.com --- This patch is based on git://git.denx.de/u-boot-atmel.git
Changed since v1 and v2 Modify the code according to Andreas's suggestion --- MAINTAINERS | 3 + arch/arm/cpu/arm926ejs/at91/Makefile | 1 + arch/arm/cpu/arm926ejs/at91/at91sam9x5_devices.c | 232 +++++++++++++++ arch/arm/cpu/arm926ejs/at91/clock.c | 12 +- arch/arm/include/asm/arch-at91/at91sam9_matrix.h | 2 + arch/arm/include/asm/arch-at91/at91sam9x5.h | 170 +++++++++++ arch/arm/include/asm/arch-at91/at91sam9x5_matrix.h | 91 ++++++ arch/arm/include/asm/arch-at91/hardware.h | 2 + board/atmel/at91sam9x5ek/Makefile | 52 ++++ board/atmel/at91sam9x5ek/at91sam9x5ek.c | 299 ++++++++++++++++++++ board/atmel/at91sam9x5ek/config.mk | 1 + boards.cfg | 1 + drivers/net/macb.c | 4 +- include/configs/at91sam9x5ek.h | 184 ++++++++++++ 14 files changed, 1050 insertions(+), 4 deletions(-) create mode 100644 arch/arm/cpu/arm926ejs/at91/at91sam9x5_devices.c create mode 100644 arch/arm/include/asm/arch-at91/at91sam9x5.h create mode 100644 arch/arm/include/asm/arch-at91/at91sam9x5_matrix.h create mode 100644 board/atmel/at91sam9x5ek/Makefile create mode 100644 board/atmel/at91sam9x5ek/at91sam9x5ek.c create mode 100644 board/atmel/at91sam9x5ek/config.mk create mode 100644 include/configs/at91sam9x5ek.h

Dear Bo Shen,
sorry, a few objections left. Wolfgang requested for last pull for -rc1 these days and I don't know if Albert is willing to pull the 6 other at91 related patches in for -rc1 or even 2012.07. So I think we don't need to hurry here. This board will make its way to mainline at least for 2012.10.

Add at91sam9x5ek board support, this board support the following SoCs AT91SAM9G15, AT91SAM9G25, AT91SAM9G35, AT91SAM9X25, AT91SAM9X35
Using at91sam9x5ek_nandflash to configure for the board Now only supports NAND with software ECC boot up
