Paul Mackerras	ca4eb46aea	Make wishbone addresses be in units of doublewords or words This makes the 64-bit wishbone buses have the address expressed in units of doublewords (64 bits), and similarly for the 32-bit buses the address is in units of words (32 bits). This is to comply with the wishbone spec. Previously the addresses on the wishbone buses were in units of bytes regardless of the bus data width, which is not correct and caused problems with interfacing with externally-generated logic.

Benjamin Herrenschmidt	bf1b98b958	litedram: Add support for booting without BRAM This adds an option to disable the main BRAM and instead copy a payload stashed along with the init code in the secondary BRAM into DRAM and boot from there Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>	4 years ago
