OpenMV Feature: Memory map support

Description

This is a first step towards gcalloc'ing memory from specific RAMs. It will also help align OpenMV's fork with upstream even more, as we have custom fixes to DMA buffers and whatnot, that this will replace.

Description

We currently have about 40 commits, in all ports, on top of master, which is great compared to the past. We think many of those patches can be upstreamed.

Q Qwen · high

Both issues are from OpenMV regarding upstreaming their fork to MicroPython. Issue #18967 specifically requests 'memory map support' as a first step to replace custom DMA buffer fixes. Issue #18969 is a broader request to upstream approximately 40 commits from OpenMV's fork. While #18967 is a specific feature request that is mentioned as part of the upstreaming effort in #18969, the candidate issue (#18969) does not resolve the specific memory map feature request in the query. They are connected topics but address different scopes - one is a specific feature, the other is a general upstreaming effort.

Suggested action

Keep both issues open. Issue #18967 should be tracked as a specific feature request for memory map support. Issue #18969 can serve as a meta-issue tracking the broader upstreaming effort, potentially referencing #18967 and other specific feature requests.
