Hi Simon, I applied the V5 patches on the latest u-boot-samsung tree and need seem to compile fine. Yes I will need to rebase them once the MMC patches get in, but will wait for comments from Minkyu Kang as well so that I can incorporate them and rebase the patch set once the MMC patches get in. Regards, Rajeshwari Shinde.
