2008-03-25Add Flex-OneNAND booting supportKyungmin Park
Flex-OneNAND is a monolithic integrated circuit with a NAND Flash array using a NOR Flash interface. This on-chip integration enables system designers to reduce external system logic and use high-density NAND Flash in applications that would otherwise have to use more NOR components. Flex-OneNAND enables users to configure to partition it into SLC and MLC areas in more flexible way. While MLC area of Flex-OneNAND can be used to store data that require low reliability and high density, SLC area of Flex-OneNAND to store data that need high reliability and high performance. Flex-OneNAND can let users take advantage of storing these two different types of data into one chip, which is making Flex-OneNAND more cost- and space-effective.

2008-02-14OneNAND Initial Program Loader (IPL) supportKyungmin Park
This patch enables the OneNAND boot within U-Boot. Before this work, we used another OneNAND IPL called X-Loader based on open source. With this work, we can build the oneboot.bin image without other program. The build sequence is simple. First, it compiles the u-boot.bin Second, it compiles OneNAND IPL Finally, it becomes the oneboot.bin from OneNAND IPL and u-boot.bin The mechanism is similar with NAND boot except it boots from itself. Another thing is that you can only use the OneNAND IPL only to work other bootloader such as RedBoot and so on. Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>
