lmb: replace lmb_reserve() and lmb_alloc_addr() API's

2025-06-25T15:50:37Z

There currently are multiple allocation API's in the LMB module. There are a couple of API's for allocating memory(lmb_alloc() and lmb_alloc_base()), and then there are two for requesting a reservation for a particular memory region (lmb_reserve() and lmb_alloc_addr()). Introduce a single API lmb_alloc_mem() which will cater to all types of allocation requests and replace lmb_reserve() and lmb_alloc_addr() with the new API. Moreover, the lmb_reserve() API is pretty similar to the lmb_alloc_addr() API, with the one difference being that the lmb_reserve() API allows for reserving any address passed to it -- the address need not be part of the LMB memory map. The lmb_alloc_addr() does check that the address being requested is actually part of the LMB memory map. There is no need to support reserving memory regions which are outside the LMB memory map. Remove the lmb_reserve() API functionality and use the functionality provided by lmb_alloc_addr() instead. The lmb_alloc_addr() will check if the requested address is part of the LMB memory map and return an error if not. Signed-off-by: Sughosh Ganu Acked-by: Ilias Apalodimas

lmb: Remove lmb_reserve_flags()

2024-12-30T19:21:55Z

lmb_reserve() is just calling lmb_reserve_flags() with LMB_NONE. There's not much we gain from this abstraction. So let's remove the latter, add the flags argument to lmb_reserve() and make the code a bit easier to follow.

lmb: make LMB memory map persistent and global

2024-09-03T20:08:50Z

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.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master.
