Subject: sunxi: emac: Rename DMA_CPU_TRRESHOLD to EMAC_RX_BUFSIZE
X-Git-Tag: v2015.07-rc1~6^2~14
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=d88c2f114970ab5153f39901324b9983d227f618;p=u-boot

sunxi: emac: Rename DMA_CPU_TRRESHOLD to EMAC_RX_BUFSIZE

Besides being spelled wrong, the DMA_CPU_TRRESHOLD define actually has
nothing to do with DMA as we only use mmio fifo access. Rename it to
EMAC_RX_BUFSIZE to properly reflect what it does.
