From: Fabio Estevam fabio.estevam@nxp.com
Since commit a13d3757f7df ("warp: Use imx_ddr_size() for calculating the DDR size") warp board no longer boots.
The reason for the breakage is that the warp board is using the DDR configuration from mx6slevk. A fundamental difference between warp and mx6slevk is that warp only uses one DDR chip select while mx6slevk uses two.
The imx_ddr() function calculates the RAM size in runtime by reading the values of registers MDCTL and MDMISC.
So in order to fix this warp boot issue, create a imximage DDR file specific to warp, where the MDCTL register is configured to only activates a single chip select.
