Hello all,
In the last few weeks I've been working on a u-boot driver for Sandisk's (MSystems) mDoc H3 device - basically, it's a DiskOnChip device which exposes a simple ATA interface to the software and works differently from previous generation DoCs (see http://www.linuxdevices.com/articles/AT2185129745.html for more).
I implemented the following low-level features in u-boot which allow using the DoC H3 as a boot device (currently all I need it for) :
- Basic partitioning - allows statically allocating sectors for
numerous binary (raw) partitions. 2. Writing IPL boot block - basically, the very initial 2KB of code than run when the CPU boots. 3. Reading and Writing of binary partitions - I place u-boot binary in one partition to be loaded and run by the IPL and the linux kernel uImage in another.
Features are exposed to the user / bootscript as simple u-boot commands.
Does anyone see benefit from this to other u-boot users? If not, what can be added / changed to make it so?
Great! I for one would very much like to have support for this in u-boot.
