Hey all, As seen by a number of patches fixing memory leaks, U-Boot has a problem with developer expectations around devm_kmalloc and friends. Namely, whereas in Linux these memory allocations will be freed automatically in most cases, in U-Boot this is only true if DEVRES is enabled. Now, intentionally, in xPL phases, we do not (and do not offer as an option) enabling DEVRES. However in full U-Boot this is left either to the user, or some drivers have select'd DEVRES on their own. This inconsistency is a problem. This series goes and deals with two small issues that were shown by having all drivers that use devm_.alloc to allocate memory also select DEVRES and then we make DEVRES no longer be a prompted option and instead select'd as needed. We do not make this unconditional as it would result in growing the resulting binary on the many platforms which have no users of the devm_.alloc family of functions.
Changes in v2: - Patch 1/3 has been merged for other reasons - Patch 2/3 has Bin's tag now - Patch 3/3 has a reworded commit message to try and be clearer about the problem, fixed a typo spotted by Michael and adds his tag. -- Tom
