I.e all proper flags like -mbig-endian and -Wl,--be8 will be set. Agreed, and I assume you cannot instead switch to LE mode when entering assembly assuming LE? The reason I ask this is - most of our development is NOT in BE mode. we will continue to manipulate and add assembly - AM335x, DRA7/OMAP5 etc.. and obviously not every code change will indulge in ensuring right markers will be in place. by ensuring readl_relaxed handles the variations, you have ensured that I dont need to care about drivers other than to ensure they use _relaxed variants. in the case of assembly, this does not seem long term manageable. > >> is the idea of BE build meant to deal with having a single BE kernel >> build work for all platforms (including LE ones)? > > Sort of.

I still dont get the usecase - other than "hey, we do this coz we can do it!".. I mean, yep, it sounds great and all.. but 4 years down the line, is this still going to work? is this going to be interesting careabout? or we are just maintaining additional code for a passing fancy or proof-of-concept?
