This adds a cache between the wishbone and litedram with the following features (at this point, it's still evolving) - 128 bytes line width in order to have a reasonable amount of litedram pipelining on the 128-bit wide data port. - Configurable geometry otherwise - Stores are acked immediately on wishbone whether hit or miss (minus a 2 cycles delay if there's a previous load response in the way) and sent to LiteDRAM via 8 entries (configurable) store queue Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
