AVR32: Get rid of board_early_init (e9a43850) · Commits · 戴 / test

board_early_init() is left over from some early prototyping work where we had to initialize the SDRAM controller ourselves. This depends on the kernel being loaded into static RAM, which just isn't possible on any commercially available products today. In order to run without a boot loader, we need to create a zImage stub or have the debugger initialize the SDRAM for us (for really low-level debugging) Signed-off-by:
