The attached application note details the steps for setting up a 64-bit Ubuntu 11.10 Oneiric virtual machine and then installing the source bundle for the i.MX53 L2.6.35-11-09-01 which was released for the the i.MX53 START_R, (Freescale PMIC) but also works on the START (Dialog PMIC).
NOTE: In the attached application note document below there is a tgz file containing patches. When copying to your Linux host make sure that CR/LF were not added by Windows when extracting and that the md5 checksums are correct for the patch files. To verify yourself, you can in the extraction directory run:
$ md5sum -c *.md5
To regenerate md5sum if incorrect here is the command for lkc, do the same for sparse changing the name:
$ md5sum lkc-1.4-lib.patch > lkc-1.4-lib.patch.md5
