[U-Boot] [PATCH v3] sunxi: Add Linksprite_pcDuino3_Nano board / defconfig

[U-Boot] [PATCH v3] sunxi: Add Linksprite_pcDuino3_Nano board / defconfig

[Adam Sampson]

This is a low-cost Allwinner A20 board with Arduino-style GPIO headers;
it features 1G RAM, 4G NAND flash, 1 micro-SD, 2 USB sockets, 1 micro
USB socket for OTG and another for power in, HDMI, SATA, 5V power for
SATA devices, gigabit Ethernet, an IR receiver, 3.5mm audio out and a
MIPI camera connector.

Like the BananaPi, this board needs GMAC_TX_DELAY set to 3 in order for
GMAC to work reliably at gigabit speeds.

For more details, see: http://linux-sunxi.org/LinkSprite_pcDuino3_Nano

Changed in v3:
- add CONFIG_GMAC_TX_DELAY=3, which corresponds to a patch in LinkSprite's
  A20 kernel; testing shows the performance is now much better at 1000M

Thanks for the patch, I've replaced the version in u-boot-sunxi/next
with this one (resulting in a forced push).

I'll likely send out a pull-req soon, so if you've any more fixes please
do them as a follow-up patch.

Regards,

Hans
