[Qemu-devel] [PATCH v3 15/20] arm: add Faraday FTMAC110 10/100Mbps ethernet support |
|
Date: |
Wed, 6 Feb 2013 17:45:19 +0800 |
From: Kuo-Jung Su <address@hidden>
The FTMAC110 is an Ethernet controller that provides AHB master capability
and is in full compliance with the IEEE 802.3 10/100 Mbps specifications.
Its DMA controller handles all data transfers between system memory
and on-chip memories.
It supports half-word data transfer for Linux. However it has a weird DMA
alignment issue:
(1) Tx DMA Buffer Address:
1 bytes aligned: Invalid
2 bytes aligned: O.K
4 bytes aligned: O.K
(2) Rx DMA Buffer Address:
1 bytes aligned: Invalid
2 bytes aligned: O.K
4 bytes aligned: Invalid (It means 0x0, 0x4, 0x8, 0xC are invalid)
