[Qemu-devel] [PATCH 08/10] aspeed/smc: Calculate checksum on normal DMA

[Cédric Le Goater]

From: Christian Svensson <address@hidden>

This patch adds the missing checksum calculation on normal DMA transfer.
According to the datasheet this is how the SMC should behave.

Verified on AST1250 that the hardware matches the behaviour.
