[U-Boot] memory block device?

[Stijn Souffriau -X (ssouffri - Sioux Embedded System at Cisco)]

Hi all,

I want to read files from an ext2 filesystem stored in a flash that is mapped to a physical address range. To be able to use the ext2 commands I think what I need is a block device (block_dev_desc_t) that treats an address range as a block device.

Does something like this already exist in u-boot or do I have to write one from scratch.

Thanks,

Stijn
