The woodburn board is based on the MX35 SOC. Support for both external (NOR) and internal (SD Card) boot mode are added. It uses the generic SPL framework to implement the internal boot mode. The following peripherals are supported: - Ethernet (FEC) - SD Card - NAND (512 MB) - NOR Flash In the internal boot mode, a simple imximage header is generated to set the address in internal RAM where the SOC must copy the SPL code. The initial setup is then demanded to the SPL itself. Signed-off-by: Stefano Babic <sbabic@denx.de> --- Changes in v2: - fix MX35 boot mode (Eric Benard) - uses SPL as binary instead of MLO (Thomas Petazzoni, Tom Rini) - NAND: the harware manufacturer decided for a different chip. Patches / issues related to NAND are dropped. - use board_init_f in SPL for setting SDRAM controller MAINTAINERS | 1 + arch/arm/cpu/arm1136/mx35/Makefile | 1 + arch/arm/cpu/arm1136/mx35/mx35_sdram.c | 137 ++++++++++++ arch/arm/include/asm/arch-mx35/sys_proto.h | 2 + board/woodburn/Makefile | 43 ++++ board/woodburn/imximage.cfg | 4 + board/woodburn/lowlevel_init.S | 38 ++++ board/woodburn/woodburn.c | 261 +++++++++++++++++++++++ boards.cfg | 2 + include/configs/woodburn.h | 34 +++ include/configs/woodburn_common.h | 313 ++++++++++++++++++++++++++++ include/configs/woodburn_sd.h | 60 ++++++ 12 files changed, 896 insertions(+) create mode 100644 arch/arm/cpu/arm1136/mx35/mx35_sdram.c create mode 100644 board/woodburn/Makefile create mode 100644 board/woodburn/imximage.cfg create mode 100644 board/woodburn/lowlevel_init.S create mode 100644 board/woodburn/woodburn.c create mode 100644 include/configs/woodburn.h create mode 100644 include/configs/woodburn_common.h create mode 100644 include/configs/woodburn_sd.h
