[PATCH 11/40] lmb: make LMB memory map persistent and global

Sughosh Ganu sughosh.ganu at linaro.org
Wed Jul 24 08:01:55 CEST 2024


The current LMB API's for allocating and reserving memory use a
per-caller based memory view. Memory allocated by a caller can then be
overwritten by another caller. Make these allocations and reservations
persistent using the alloced list data structure.

Two alloced lists are declared -- one for the available(free) memory,
and one for the used memory. Once full, the list can then be extended
at runtime.

Changes since rfc:
* Squash patches 9 - 11, 13  from the rfc v2 series into a single
  patch to make it bisectable.
