as Tom Rini suggested, I tried to update the mtd,ubi and ubifs subsystem with linux v3.15:
commit 1860e379875dfe7271c649058aeddffe5afd9d0d Author: Linus Torvalds torvalds@linux-foundation.org Date: Sun Jun 8 11:19:54 2014 -0700
Linux 3.15
First patch in this patchserie is a patch, which contains some small changes based on the linux v3.14 patchserie [1]
Second patch is the real sync with linux v3.15 patch, based on [1], created in the following way:
1) checkout linux v3.14 in the linux tree 2) copy all files [2] from the linux tree to the u-boot tree 3) "git diff" shows a patch, which contains all u-boot specific changes -> save it for later use 4) checkout linux v3.15 in the linux tree 5) copy all files [2] from the linux tree to the u-boot tree 6) "git diff" shows all linux specific changes between v3.14 and v3.15 7) apply u-boot specific changes patch from step 3 8) fix warnings, errors 9) compile (MAKEALL compiles clean for arm, powerpc and mips) 10) test, test, test (done on the imx6 based aristainetos board) 11) commit it, make patch and send to ML
