Subject: [Qemu devel PATCH v5 0/3] Add SmartFusion2 EMAC block
Date: Tue, 14 Apr 2020 20:32:28 +0530 [thread overview]
Message-ID: <1586876551-3695-1-git-send-email-sundeep.lkml@gmail.com> (raw)
From: Subbaraya Sundeep <sundeep.lkml@gmail.com>
This patch set emulates Ethernet MAC block
present in Microsemi SmartFusion2 SoC.
v5:
As per Philippe comments:
Returned size in receive function
Added link property to pass DMA memory
Used FIELD() APIs
Added mac_addr in emac state
Used FIELD_EX32 and FIELD_DP32 APIs
Simplified if else logics in emac_write/read
v4:
Added loop back as per Jason's comment
v3:
Added SmartFusion2 ethernet test to tests/acceptance
v2:
No changes. Fixed Signed-off mail id in patch 2/2
Testing:
1. Download u-boot.bin, uImage and msf2-devkit.dtb from
https://github.com/Subbaraya-Sundeep/qemu-test-binaries.git
2. Copy uImage and msf2-devkit.dtb to suitable Qemu tftp directory
3. Launch Qemu by
./arm-softmmu/qemu-system-arm -M emcraft-sf2 -serial mon:stdio -kernel \
u-boot.bin -display none -nic user,tftp=<qemu tftp directory>
Example:
./arm-softmmu/qemu-system-arm -M emcraft-sf2 -serial mon:stdio -kernel u-boot -display none -nic user,tftp=/home/hyd1358/qemu_tftp
