[U-Boot] [PATCH] fsl-ddr: Fix the turnaround timing for TIMING_CFG_4

2010-02-01 Thread Dave Liu
Read-to-read/Write-to-write turnaround for same chip select of DDR3 memory, BL/2+2 cycles is enough for these turnarounds. Cutting down the turnaround from BL/2+4 to BL/2+2 will improve the memory performance. Signed-off-by: Dave Liu --- cpu/mpc8xxx/ddr/ctrl_regs.c |6 +++--- 1 files changed
