[U-Boot] [PATCH v3 0/4] uboot sata support for sunxi platform

[U-Boot] [PATCH v3 0/4] uboot sata support for sunxi platform

[Ian Campbell]

This is the third version of my series to add support for AHCI to the
sunxi platform. This uses the existing ahci platform support already
present in u-boot. Most of the sunxi specific code comes from the Linux
platform patches.

Since last time I've cut out all the unused register #defines and made
the Calxeda midway platform use the scsi_init hook (new patch).

I've tested this only on cubietruck, but it is enabled for Olinino
Micro, cubieboard and cubieboard2 based on inspection of the Linux DTS
files. I have also now tested on Calxeda midway.

Once again as requested I am also cross posting to the main uboot
mailing list since the first two patches are generic and don't rely on
sunxi stuff and so could go into mainline now.

Ian.

[U-Boot] [PATCH v3 1/4] ahci-plat: Provide a weak scsi_init hook

[Ian Campbell]

This allow the platform to register the platform ahci device.

In theory this could perhaps be used by highbank. I have access to a
Midway system (close enough for testing purposes, I think) but since
Calxeda has folded I'm not sure it is worth it, and I am not entirely
keen on reflashing firmware on the system I have access too (no safety
net)...

[U-Boot] [PATCH v3 3/4] ahci: wait longer for link.

[Ian Campbell]

I have observed timeouts on a cubietruck.

The increase to 40ms is completely arbitrary and Works For Me(tm). I
couldn't find a good reference for how long you are supposed to wait,
although googling around it seems like tens of ms rather than single
digits is more common. I don't think there is any harm in waiting a bit
longer.

[U-Boot] [PATCH v3 4/4] ahci: provide sunxi SATA driver using AHCI platform framework

[Ian Campbell]

This enables the necessary clocks, in AHB0 and in PLL6_CFG. This is done
for sun7i only since I don't have access to any other sunxi platforms
with sata included.

The bulk of the code is taken from the Linux ahci sunxi platform driver
patches, adjusted for u-boot.

This adds the "PORT_DMA" tweaks to the core driver, under a suitable
ifdef.

This option is enabled for Cubieboard, Cubieboard2, Cubietruck and
Olinuxino Micro based on contents of Linux DTS files, including SATA
power pin config taken from the DTS. All build tested, but runtime
tested on cubietruck (FEL) only.

v3:

    Drop unused register definitions

v2:

    make AHCI configurable per board, enabled for cubieboard,
    cubieboard2, cubietruck and Olinuxino Micro.

Oops:                          ^three

That is:
        ahci-plat: Provide a weak scsi_init hook
        highbank: use scsi_init hook
        ahci: wait longer for link.

are all suitable for main line.

[U-Boot] [linux-sunxi] [PATCH v3 0/4] uboot sata support for sunxi platform

[Ezaul Zillmer]

Hi Ian .. 

You would have a repository with these updates where I could play with git, 
compile and test my cubieboard2 using kernel 3.14.rc5 

I'm waiting! to test your boot! 
thank you

What is not wrong that the boot SCSI wheel 
Where am I going wrong with leaving boot.cmd? 
use today as well 

boot.cmd 
setenv bootargs console = tty0 console = ttyS0, 115200 = hdmi.audio EDID: 0

bootm 0x46000000 - 0x49000000 

MMC for swap SCSI? 

It should be assimo Boot.cmd? 

setenv bootargs console = tty0 console = ttyS0, 115200 = hdmi.audio EDID: 0 
= disp.screen0_output_mode EDID: 1280x800p60 root = / dev/sda1 rootfstype =

The first two and the last one are using a totally different syntax,
only one of them can be correct, I suggest you check the uboot help/docs
and experiment by hand on the uboot console before trying to construct a
boot.scr.

WTF?

I've noticed 'ext4load' twice today, once in the mail above and once in the 'fedora on panda' blog post. What's stopping people from using the generic 'fsload' commands?
