Subject: powerpc: t1024: Fix SRDS_MAX_LANES value
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=fbe44dd1aae749255bcd7e458d4a91cac4181994;p=u-boot.git

powerpc: t1024: Fix SRDS_MAX_LANES value

T1023 and T1024 have 4 SerDes lanes. Fix macro SRDS_MAX_LANES
and use this macro instead of hard-coded value in t1024_serdes.c.
