Hi, I'm using a Device Tree with more then 32 reserved memory regions and I'm seeing the following error while booting the Kernel: [ 0.000000] OF: reserved mem: not enough space all defined regions. My understanding is that this is due to the hard-coded value of MAX_RESERVED_REGIONS in drivers/of/of_reserved_mem.c Googling around, I found this old discussion [1] in which Miles suggests to add a CONFIG_MAX_OF_RESERVED_REGIONS kconfig option to configure MAX_RESERVED_REGIONS. Rob replied to Miles' email saying that he would prefer MAX_RESERVED_REGIONS to be dynamic. However, later in the thread, it looks like making MAX_RESERVED_REGIONS dynamic poses some implementation issues [2]. At that point the discussion seemed to have stopped. Is there any chance for the patch proposed by Miles to be reconsidered? Regards, Daniele [1] https://lkml.org/lkml/2018/11/21/423 [2] https://lkml.org/lkml/2018/11/28/275
