[PATCH v2 0/5] PPC32/ioremap: Use memblock API to check for RAM
From: Jonathan NeuschÃfer
Date: Tue Mar 27 2018 - 20:25:59 EST
v1: https://www.spinics.net/lists/linux-mm/msg145939.html
This patchset makes it possible to allocate MMIO ranges that are between
the two RAM chunks on the Wii, MEM1 and MEM2, not only with ioremap
(which previously worked through a hack) but also with kernel/resource.c.
Changes in v2:
- I added back the p < virt_to_phys(high_memory) check in
__ioremap_caller because high memory should be allocatable through
ioremap
- I expanded the commit messages a bit
