Subject: MX28: DMA: Prolong the DMA timeout
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=1375f044d96f31987b0f4d3feb1fb01205939f3b;p=u-boot.git

MX28: DMA: Prolong the DMA timeout

Load from SPI flash can create a long DMA chain, which can take long
time to transfer. Change the DMA timeout to roughly 10s to prevent
such long chains misreporting errors.
