Each of these contains four bits, one for -each lane in the bank. SerDes Erratum SERDES8 requires that SRDS_LPD_B2 and -SRDS_LPD_B3 be set to 0b1111. This forces banks two and three to be powered -down at reset. - -To re-enable these banks in U-Boot, two hwconfig are available: -"fsl_srds_lpd_b2" and "fsl_srds_lpd_b3". The value passed via fsl_srds_lpd_b2 -is written into SRDS_LPD_B2, and the value passed via fsl_srds_lpd_b3 is into -SRDS_LPD_B3. Each bit represents one of each bank, and a value of '1' -indicates that the lane should be powered down. - -For example, to indicate that both SerDes banks 2 and 3 are powered down, add -the following to hwconfig: - - serdes:fsl_srds_lpd_b2=0xf,fsl_srds_lpd_b3=0xf - -The "0xf" is a mask that corresponds to the 4 lanes A-D. The most significant -bit corresponds to lane A. To indicate that just lane A of bank 3 is to be -powered down, use: - - serdes:fsl_srds_lpd_b3=8 - -These options should be specified only if U-Boot does not automatically power -on the correct lanes. |
