From 031acdbae89515371f794d01df819b490ff7ca9c Mon Sep 17 00:00:00 2001 From: Hou Zhiqiang Date: Fri, 9 Dec 2016 16:09:00 +0800 Subject: armv8/fsl_lsch2: Add chip power supply voltage setup Set up chip power supply voltage according to voltage ID. The fuse status register provides the values from on-chip voltage ID fuses programmed at the factory. These values define the voltage requirements for the chip. Main operations: 1. Set up the core voltage 2. Set up the SERDES voltage and reset SERDES lanes 3. Enable/disable DDR controller support 0.9V if needed Signed-off-by: Hou Zhiqiang Reviewed-by: York Sun --- include/fsl_ddr_sdram.h | 1 + 1 file changed, 1 insertion(+) (limited to 'include') diff --git a/include/fsl_ddr_sdram.h b/include/fsl_ddr_sdram.h index 1404c57..b8de46b 100644 --- a/include/fsl_ddr_sdram.h +++ b/include/fsl_ddr_sdram.h @@ -173,6 +173,7 @@ typedef struct ddr4_spd_eeprom_s generic_spd_eeprom_t; /* DDR_CDR1 */ #define DDR_CDR1_DHC_EN 0x80000000 +#define DDR_CDR1_V0PT9_EN 0x40000000 #define DDR_CDR1_ODT_SHIFT 17 #define DDR_CDR1_ODT_MASK 0x6 #define DDR_CDR2_ODT_MASK 0x1 -- cgit v1.1
