E.g. the kernel. I am new to dealing with the i.MX53. I have done alot of work with various PowerPC's, as well as OMAP ARM's. I contributed to getting Xilinx support into the kernel.org source. I have been playing around with a variety of vendor and consultant trees including the Linaro ones. I am familiar with u-boot, device tree. I was not familiar with the state of device trees and ARM in current kernels. Once I know what I am starting from I can deal with whatever state the current kernel is in. I would prefer to work there, I would hope that in six months or so this should be sorted out. Maybe I can help. thank You
