From d1d075a5587bafaa118a53af64c0feaff067fc9b Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Wed, 15 Feb 2017 12:31:53 +0100 Subject: [PATCH] net: mvpp2: enable building on 64-bit platforms The mvpp2 is going to be extended to support the Marvell Armada 7K/8K platform, which is ARM64. As a preparation to this work, this commit enables building the mvpp2 driver on ARM64, by: - Adjusting the Kconfig dependency - Fixing the types used in the driver so that they are 32/64-bits compliant. We use dma_addr_t for DMA addresses, and unsigned long for virtual addresses. It is worth mentioning that after this commit, the driver is for now still only used on 32-bits platforms, and will only work on 32-bits platforms. Changed by Stefan for U-Boot: Removed the Kconfig change as it does not apply to U-Boot this way.
