[PATCH v4 15/27] lmb: init: initialise the lmb data structures during board init

Mon Aug 26 13:59:28 CEST 2024


The memory map maintained by the LMB module is now persistent and
global. This memory map is being maintained through the alloced list
structure which can be extended at runtime -- there is one list for
the available memory, and one for the used memory. Allocate and
initialise these lists during the board init.
