Hello Bruce!
Please review and merge this series of patches in Axxia branches from
linux-yocto-4.1.
Changes included in this series (axxia tags: 1.61-1.63):
Linux 1.61 Changes
- Rebase from 4.1.39 to 4.1.42.
- Fix warnings introduced by the rebased mentioned above.
- Add tracing of NCR, PEI, and PCI accesses. Tracing can be enabled
using the bootargs or after booting using /sys.
- For NCR, use trace for all accesses, and trace_value_read
to display the value read after a read.
- For PEI and PCI, use trace.
- PCI Updates.
- Add a work around for a hardware problem. If the link is
not established at the requested number of lanes, reduce
and try again. If there is no link at x1, fail.
- Update the LOS work around to work the the lane reduction
work around mentioned above.
- Add a new configuration for 5600, unsupported on the Axxia
development board, configuration 5.
- In configuration 2, 5600, set sw_port_1 to 0x2 instead of 0x4.
- Always set the number of phys to 4 for 5600 and 1 for 6700.
- Always set the link width speed change register to x1 and use
the link control register to set the desired width.
- USB Updates and USB support for 5600 B* parts.
- Use HCRST for soft resets in the driver and don't reset the
PHY seperately sinc HCRST resets the PHY.
- Move all changes to constant values to the early init code
(SPL) instead of the driver.
Linux 1.62 Changes
- Fix a boot problem on 5500. In the new Axxia fault code, exceptions
need to be masked on 5500 by default.
- The final change to the PCI work around (If the link is not established
at the requested number of lanes...) was not included. As the hardware
does not have the correct default class code, software needs to set it.
With the width change work around, the class code needs to be set to the
correct value each time the width is changed.
- Update the default configurations to get rid of some warnings when using
systemd instead of sysv init.
Linux 1.63 Changes
- Update USB to use the original reset sequence instead of asserting HCRST.
The HCRST reset breaks USB2 and USB3 in some cases.
- Fixes for PEI configuration 5.
If all the patches are ok, please pull them from

Pull
standard/axxia/base-1.63 -> standard/axxia/base
standard/preempt-rt/axxia/base-1.63 -> standard/preempt-rt/axxia/base
If you add more patches to standard/(preempt-rt)/axxia/base beforehand
please notify me. I will rebase our changes so you can do a clean,
fast-forward pull.
Thank you,
