[U-Boot] [PATCH v2 0/9] arm: ls102xa: Add Freescale LS102xA SoC and LS1021AQDS/TWR board support

[Alison Wang]

This series contain the support for Freescale LS102xA SoC and LS1021AQDS/TWR board.

[U-Boot] [PATCH v2 01/10] arm: ls102xa: Add Freescale LS102xA SoC support

[Alison Wang]

The QorIQ LS1 family is built on Layerscape architecture,
the industry's first software-aware, core-agnostic networking
architecture to offer unprecedented efficiency and scale.

Freescale LS102xA is a set of SoCs combines two ARM
Cortex-A7 cores that have been optimized for high
reliability and pack the highest level of integration
available for sub-3 W embedded communications processors
with Layerscape architecture and with a comprehensive
enablement model focused on ease of programmability.

Albert,

As you can see, Freescale starts to make ARM core SoCs on QorIQ product line.
As previously discussed, I will maintain fsl-qoriq repository to host these
patches. Beside ARMv8, I am new to ARM cores. To start, I would like to solicit
your comments/ack for this series.

It will be helpful if you can share how ARM maintainers do the daily jobs like
sending notice, pull requests, etc.

[U-Boot] [PATCH v2 03/10] net: Merge asm/fsl_enet.h into fsl_mdio.h

[Alison Wang]

From: Claudiu Manoil <claudiu.manoil@freescale.com>

fsl_enet.h defines the mapping of the usual MII management
registers, which are included in the MDIO register block
common to Freescale ethernet controllers. So it shouldn't
depend on the CPU architecture but it should be actually
part of the arch independent fsl_mdio.h.

To remove the arch dependency, merge the content of
asm/fsl_enet.h into fsl_mdio.h.
Some files (like fm_eth.h) were simply including fsl_enet.h
only for phy.h. These were updated to include phy.h instead.

Don't reinvent the wheel. You can use mb() where you use tsec_mdio_sync();

[U-Boot] [PATCH v2 06/10] driver/ddr/freescale: Add support of accumulate ECC

[Alison Wang]

From: York Sun <yorksun@freescale.com>

If less than 8 ECC pins are used for DDR data bus width smaller than 64
bits, the 8-bit ECC code will be transmitted/received across several beats,
and it will be used to check 64-bits of data once 8-bits of ECC are
accumulated.

[U-Boot] [PATCH v2 08/10] driver/ddr/fsl: Add support of overriding chip select write leveling

[Alison Wang]

From: York Sun <yorksun@freescale.com>

JEDEC spec allows DRAM vendors to use prime DQ for write leveling. This
is not an issue unless some DQ pins are not connected. If a platform uses
regular DIMMs but with reduced DDR ECC pins, the prime DQ may end up on
those floating pins for the second rank. The workaround is to use a known
good chip select for this purpose.

[Alison Wang] Yes, I will prepare a separate patch for it and add the commit
message. Thanks.

+Overview
+--------
+The LS1021ATWR is a Freescale reference board that hosts the LS1021A SoC.
+
+LS1021A SoC Overview
+------------------
+The QorIQ LS1 family, which includes the LS1021A communications processor,
+is built on Layerscape architecture, the industry's first software-aware,
+core-agnostic networking architecture to offer unprecedented efficiency
+and scale.
+
+A member of the value-performance tier, the QorIQ LS1021A processor provides
+extensive integration and power efficiency for fanless, small form factor
+enterprise networking applications. Incorporating dual ARM Cortex-A7 cores
+running up to 1.0 GHz, the LS1021A processor delivers pre-silicon CoreMark
+performance of over 6,000, as well as virtualization support, advanced

The numbering in the cover letter (0/9) does not match that in the
individual patches (n/10). Is this normal?

Sorry, it's my mistake. It should be 0/10 in the cover letter, not 0/9.

Alison,

Please respin your patches. It has been a while since you submitted them. For
your convenience, I have rebased your patches to v2014.10-rc1 and converted to
the latest Kconfig. They can be compiled but I didn't verify on boards. Please
verify and address the review comments.

http://git.denx.de/?p=u-boot/u-boot-fsl-qoriq.git;a=shortlog;h=refs/heads/test

Please submit your new patches based on u-boot-fsl-qoriq/master.
