Subject: configs: ls1021a: Reserve low memory for CMA
X-Git-Tag: v2020.04-rc2~16^2~6
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=feb8fa2ef0a5ff6627baac749a72dfaa15e37714;p=oweals%2Fu-boot.git

configs: ls1021a: Reserve low memory for CMA

The default reserved memory for CMA is high memory. If LPAE is enabled,
highmem pages are non-remapped and can not be used with
dma_alloc_coherent. This patch will reserve low memory for CMA and fix
the issue on LS1021A.
