I'm start with a port for a new customer board with NOR-flash only. Our customer don't like use AT91Bootstrap.

I look at the source, but don't found any initialization code for AT91SAM926x.

My question:

Are there any plans or patches which support to use u-boot without AT91Bootstrap? or Should I do this by myself?

I have tested a solution based on U-Boot-1.1.5 as modified by Atmel. The adaptation to booting via NOR flash itself was written by Alessandro Rubini:

Although it is based on old code, the documentation of the problem of booting from NOR flash on the AT91SAM9263 is worth reading.
