Benjamin Herrenschmidt	63f10450a6	litedram: Fix DRAM init mem using too many address bits Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>	6 years ago
Benjamin Herrenschmidt	eaf6883e57	litedram: Update to latest LiteX/LiteDRAM version Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>	6 years ago
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>	6 years ago
Benjamin Herrenschmidt	6fe077910b	litedram: Add simulation support This adds a simulated litedram model along with the necessary Makefile gunk to verilate it and wrap it for use by ghdl. The core_dram_tb test bench is a variant of core_tb with LiteDRAM simulated. It's not built by default, an explicit make core_dram_tb is necessary as to not require verilator to be installed for the normal build process (also it's slow'ish).
