Freescale ARM-based Layerscape LS102xA contain a SATA controller
which comply with the serial ATA 3.0 specification and the
AHCI 1.3 specification.
This patch adds SATA feature on ls1021aqds and ls1021atwr boards.

Sorry for top posting, replying from my phone.
Please use macros instead of numbers. It's still better than putting magic
numbers in the code. And please move it out of board files.

What are these numbers?
I don't like magic number either, but I don't have a choice.
These numbers are used to overwrite the default value which are not working for
sata. They are gotten from validation team.
Their meanings are documented in RM. Is it necessary to re-explain bit by bit
again?
Same reasons for ls2085.

Re: [U-Boot] [PATCH v2] arm/ls1021a: Add sata support on qds and twr board
I don't understand. This workaround is our board specific and actually ls1021
specific. I thought about merging all the LS SATA initialization into one file,
but that didn't reduce many code. So I add this one by one board.

Re: [U-Boot] [PATCH v2] arm/ls1021a: Add sata support on qds and twr board
No, the old patch still use board files. Even it is a common board file, it is not common for other than freescale boards. ls2085 didn't have an soc file to start with. When you have a situation like this, you create one. I will be out in next few days, please work with Prabhakar.

Yuantian,
In your patch, you are using CONFIG_SYS_FSL_ERRATUM_A008407. Are you saying
this is a board erratum, not an SoC erratum?

I don't understand. This workaround is our board specific and actually ls1021
specific. I thought about merging all the LS SATA initialization into one file,
but that didn't reduce many code. So I add this one by one board.

The soc workarounds belongs to soc file, not board file, so you don't have to
copy the code to every board. Our boards are not the only boards with this SoC.

Sorry for top posting, replying from my phone.
Please use macros instead of numbers. It's still better than putting magic
numbers in the code. And please move it out of board files.
Yuantian:
Please move what out of board files, these magic numbers or sata init function?

I don't like magic number either, but I don't have a choice.
These numbers are used to overwrite the default value which are not working for

Re: [U-Boot] [PATCH v2] arm/ls1021a: Add sata support on qds and twr board
On ls2085 we had a soc file which can put all the soc specific function in it.
But on ls1021, there is no such file unless I create one for SATA.
Please see the patch I first submit. Do you prefer this way?

Yes, this is a ls1021 specific errata.
