Why is this happening? I am fine in reverting this but we need to fix
the detection. Is it due memory callibration problems?
The problem here is that warp uses the DDR initialization from mx6sl-evk.
From configs/mx6slevk_defconfig:
CONFIG_SYS_EXTRA_OPTIONS="IMX_CONFIG=board/freescale/mx6slevk/imximage.cfg,MX6SL"
The usage of imx_ddr_size() revealed that the DDR size is not being
programmed correctly for the warp board.
That means that reverting just hides the problem.
...
The proper way to fix this is to create a board/warp/imximage.cfg file
with the DDR configuration done specifically for this board.
Then imx_ddr_size() should work without issues for warp.
Until this is done, better go with the revert patch for now:

Let's say: if there won't be any fix before the release, it is ok to
revert this.

Stefano
