Subject: [U-Boot] [PATCH 0/4] dma-mapping: Add cache flush/invalidation to dma_{un}map_single
Date: Fri, 15 Nov 2019 17:25:01 +0530 [thread overview]
Message-ID: <20191115115505.893-1-vigneshr@ti.com> (raw)
Drivers (especially frameworks ported from Linux such as USB) expect
dma_{un}map_single() APIs to take care of cache maintenance. But this is
not the case in U-Boot and few drivers take care of flushing caches
locally. Instead add flush/invalidate calls to DMA APIs in arch specific
dma-mapping.h file so that per driver implementation of these APIs can
be avoided.
I don't have all the affected hardwares. Would greatly appreciate if
these patches work fine on the affected platforms.

asm: dma-mapping.h: Fix dma mapping functions
mmc: tmio-common: Drop custom dma mapping functions
mtd: denali: Drop custom dma mapping functions
net: macb: Drop local cache flush
