Subject: aspeed/i2c: Fix DMA address mask
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=7492515909f043c4d82909ecdebb8643ed944c68;p=qmiga%2Fqemu.git

aspeed/i2c: Fix DMA address mask

The RAM memory region is now used for DMAs accesses instead of the
memory address space region. Mask off the top bits of the DMA address
to reflect this change.
