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. [port from linux kernel 3.4 commit 570469f3bde7f71cc1ece07a18d54a05b6a8775d] Signed-off-by: Mike Dunn <mikedunn@newsguy.com> |
