Dear Mike Dunn, > This patch adds a driver for the diskonchip G4 nand flash device. It is > based on the driver from the linux kernel. > > This also includes a separate SPL driver. A separate SPL driver is used > because the device operates in a different mode (reliable mode) when > loading a boot image, and also because the storage format of the boot > image is different from normal data (pages are stored redundantly). The > SPL driver basically mimics how a typical IPL reads data from the device. > The special operating mode and storage format are used to compensate for > the fact that the IPL does not contain the BCH ecc decoding algorithm (due > to size constraints). Although the u-boot SPL *could* use ecc, it > operates like an IPL for the sake of simplicity and uniformity, since the > IPL and SPL share the task of loading the u-boot image. As a side benefit, > the SPL driver is very small. > > Signed-off-by: Mike Dunn <miked...@newsguy.com>
Try #ifdef U_BOOT instead of #if 0, no? Best regards, Marek Vasut _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
