According to some discussion in previous threads and hopefully I do not misinterprete Wolfgang's will about the direction that U-Boot will have in future, the nand_spl code is obsolete and it remains for the already supported boards. However, new boards must implement SPL using the SPL framework. New boards using nand_spl will not be integrated in mainline. > +######################################################################### > diff --git a/board/eukrea/cpuimx25/config.mk b/board/eukrea/cpuimx25/config.mk > new file mode 100644 > index 0000000..18b2883 > --- /dev/null > +++ b/board/eukrea/cpuimx25/config.mk > @@ -0,0 +1,5 @@ > +ifdef CONFIG_NAND_SPL > +CONFIG_SYS_TEXT_BASE = 0x810c0000 > +else > +CONFIG_SYS_TEXT_BASE = 0x81200000 > +endif config.mk is obsolete in board's directory.

this board is based on an i.MX25 from Freescale. It consists of a SOM containing : - NAND flash (internal or external boot supported and tested) - mDDR (64MB tested) - ethernet PHY connected in RMII mode (tested) and a baseboard containing : - a serial transceiver on UART1 (tested) - a SDCard connector on eSDHC1 (tested but disabled until Benoît's fix gets applied) bootlog : U-Boot 2012.10-rc1-00003-gdd12be5 (Sep 23 2012 - 13:53:21) CPU: Freescale i.MX25 rev1.2 at 399 MHz Reset cause: POR DRAM: 64 MiB NAND: 256 MiB MMC: In: serial Out: serial Err: serial Net: FEC Hit any key to stop autoboot: 0 Signed-off-by: Eric Bénard <eric@eukrea.com> --- v2: rebased against 2012.10-rc1, disabled eSDHC until proper fix from Benoît gets applied, updated bootlog.
