|

Memory type descriptors. These describe the capabilities of a type of memory in the SoC. Each type of memory
|
|
map consist of one or more regions in the address space.
|
|
|
|
Each type contains an array of prioritised capabilities; types with later entries are only taken if earlier
|
|
ones can't fulfill the memory request.
|
|
|
|
The prioritised capabilities work roughly like this:
|
|
- For a normal malloc (MALLOC_CAP_DEFAULT), give away the DRAM-only memory first, then pass off any dual-use IRAM regions,
|
|
finally eat into the application memory.
|
|
- For a malloc where 32-bit-aligned-only access is okay, first allocate IRAM, then DRAM, finally application IRAM.
|
|
- Application mallocs (PIDx) will allocate IRAM first, if possible, then DRAM.
|
|
- Most other malloc caps only fit in one region anyway.
