# SDRAM Memory Configuration Parameters
# sdram_config configures the SDRAM interface specifically for the actual memory part used
# It is VERY critical to set this parameter correctly or the board will not boot.
# For the BCM4707/8/9/81:
#
# Bits Definition
# ----- -----------------------------------------------------------------------------------------------------------
# 15:11 Reserved
# 10:8 Column Size: 000 = 2048 columns; 001 = 1024 columns; 010 = 512 columns
# 7 Reserved
# 6 0 = 4 banks; 1 = 8 banks
# NOTE: For 4 banks, columns can be 512, 1024, or 2048. For 8 banks, columns can only be 1024 or 2048.
# 5 Reserved
# 4:0 CAS latency: valid range is 3-14, all others reserved
#
# Set 128MB (1Gbit) of DDR3 (DDR3M64X16), x16, 8 banks, CL=11
sdram_config=0x014B
# Normally the 4708/9/81 do not use the sdram_refresh parameter, however for the 4708/9/81, the sdram_refresh parameter can
# be used to speed up the refresh interval of the DDR3. This is only needed for DDR3 and only if the junction temperature
# of the DDR3 part is expected to get hotter than 85 degC. If this adjustment is needed, set the sdram_refresh parameter
# according to the following equation:
# sdram_refresh = 6232 * DDR3 clock (in MHz) / 800 |
