* Training search & read result routine
* This function implements the search algorithm
* first it calls the function ddr3_tip_ip_training_wrapper_int which triggers the search from l2h and h2l
* this function handles rx and tx search cases
* in case of rx it only triggers the search (l2h and h2l)
* in case of tx there are 3 optional algorithm phases:
* phase 1:
* it first triggers the search and handles the results as following (phase 1):
* each bit, which defined by the search two edges (e1 or VW_L and e2 or VW_H), match on of cases:
* 1. BIT_LOW_UI 0 =< VW =< 31 in case of jitter use: VW_L <= 31, VW_H <= 31
* 2. BIT_HIGH_UI 32 =< VW =< 63 in case of jitter use: VW_L >= 32, VW_H >= 32
* 3. BIT_SPLIT_IN VW_L <= 31 & VW_H >= 32
* 4. BIT_SPLIT_OUT* VW_H < 32 & VW_L > 32
* note: the VW units is adll taps
* phase 2:
* only bit case BIT_SPLIT_OUT requires another search (phase 2) from the middle range in two directions h2l and l2h
* because only this case is not locked by the search engine in the first search trigger (phase 1).
* phase 3:
* each subphy is categorized according to its bits definition.
* the sub-phy cases are as follows:
* 1.BYTE_NOT_DEFINED the byte has not yet been categorized
* 2.BYTE_HOMOGENEOUS_LOW 0 =< VW =< 31
* 3.BYTE_HOMOGENEOUS_HIGH 32 =< VW =< 63
* 4.BYTE_HOMOGENEOUS_SPLIT_IN VW_L <= 31 & VW_H >= 32
* or the center of all bits in the byte =< 31
* 5.BYTE_HOMOGENEOUS_SPLIT_OUT VW_H < 32 & VW_L > 32
* 6.BYTE_SPLIT_OUT_MIX at least one bits is in split out state and one bit is in other
* or the center of all bits in the byte => 32
* after the two phases above a center valid window for each subphy is calculated accordingly:
* center valid window = maximum center of all bits in the subphy - minimum center of all bits in the subphy.
* now decisions are made in each subphy as following:
* all subphys which are homogeneous remains as is
* all subphys which are homogeneous low | homogeneous high and the subphy center valid window is less than 32
* mark this subphy as homogeneous split in.
* now the bits in the bytes which are BYTE_SPLIT_OUT_MIX needed to be reorganized and handles as following
* all bits which are BIT_LOW_UI will be added with 64 adll,
* this will hopefully ensures that all the bits in the sub phy can be sampled by the dqs
