The MINI2416 board is based on a Samsung's S3C2416 SoC and has 64MB DDR2 SDRAM, 256MB NAND Flash, a LAN9220 Ethernet Controller and a WM8731 Audio CODEC. This U-Boot port was implemented and tested on a unit bought to Boardcon (http://www.armdesigner.com/) but there are some other chinese providers that can supply it with a selectable NAND chip from 128MB to 1GB.
Signed-off-by: José Miguel Gonçalves jose.goncalves@inov.pt --- Changes for v2: - Coding style cleanup - Use of Use of clrbits_le32(), setbits_le32() and clrsetbits_le32() - Use of register bit macros instead of magic numbers - Use of serial and rtc drivers implemented for s3c24x0
Changes for v3: - Changed target name from u-boot-ubl.bin to u-boot-pad.bin - Removed magic numbers - Changes to support new SPL framework --- MAINTAINERS | 4 + board/boardcon/mini2416/Makefile | 47 ++++++++ board/boardcon/mini2416/config.mk | 4 + board/boardcon/mini2416/mini2416.c | 104 ++++++++++++++++ board/boardcon/mini2416/mini2416_spl.c | 202 ++++++++++++++++++++++++++++++++ board/boardcon/mini2416/u-boot-spl.lds | 63 ++++++++++ boards.cfg | 1 + include/configs/mini2416.h | 202 +++++++++++++++++++++++++++++++ 8 files changed, 627 insertions(+) create mode 100644 board/boardcon/mini2416/Makefile create mode 100644 board/boardcon/mini2416/config.mk create mode 100644 board/boardcon/mini2416/mini2416.c create mode 100644 board/boardcon/mini2416/mini2416_spl.c create mode 100644 board/boardcon/mini2416/u-boot-spl.lds create mode 100644 include/configs/mini2416.h
