[Yuan Yao]

arm: ls1021a: merge SoC specific code in a separate file
arm: ls102xa: enable all the snoop signal for masters.
ls102xa: Enable snoop and DVM message requests.
armv7/fsl-ls102xa: Workaround for DDR erratum A008514
Changed in v2:
        Update the write value to 63b2_0042h;

move erratum a008336 and a008514 to soc specific file
Changed in v3:
       	Fix a typo issue.
        In function "erratum_a008514"
	"#ifdef CONFIG_SYS_FSL_DCSR_DDR2_ADDR" should be
	"#ifdef CONFIG_SYS_FSL_DCSR_DDR3_ADDR"
Changed in v2:
	Update the patch commit message.

[U-Boot] [PATCH 1/5] arm: ls1021a: merge SoC specific code in a separate file

[Yuan Yao]

[U-Boot] [PATCH 2/5] arm: ls102xa: enable all the snoop signal for masters.

[Yuan Yao]

Enable the IP feature's snoop signal to support
hardware snoop for cache coherence.

SNPCNFGCR contains the bits to drive snoop signal
for various masters.

Yuan,

I'm not sure both snoop request and DVM are supported on every port. Do you need
to check them before setting?

[U-Boot] [PATCH 3/5] ls102xa: Enable snoop and DVM message requests.

[Yao Yuan]

Hi York,

I'm sorry I'm late replies.

Thanks for reminding me.
We have some investigates and then depend on the document we think both snoop request and DVM are supported on those port.
So we think the setting should be ok in here.

Best Regards,
Yuan Yao

I think your conclusion is correct but not your reasoning. I did some digging
myself. These registers (snoop control) have top two bits indicating if a slave
interface supports snoop and/or DVM messages. If the feature is disabled,
writing the enabling bit is ignored.

No more action for you.

[U-Boot] [PATCH v2 4/5] armv7/fsl-ls102xa: Workaround for DDR erratum A008514

[Yuan Yao]

This is a workaround for hardware erratum.
Write the value of 63b2_0042h to EDDRTQCFG will optimal the
memory controller performance.

The value: 63b2_0042h comes from the hardware team.

Changed in v2:
	Update the write value to 63b2_0042h;

[U-Boot] [PATCH v3 5/5] move erratum a008336 and a008514 to soc specific file

[Yuan Yao]

As the errata A008336 and A008514 do not apply to all LS series SoCs
(such as LS1021A, LS1043A) we move them to an soc specific file

Signed-off-by: Yuan Yao <yao.yuan@freescale.com>

Changed in v3:
	Fix a typo issue.
	In function "erratum_a008514"
	"#ifdef CONFIG_SYS_FSL_DCSR_DDR2_ADDR" should be
	"#ifdef CONFIG_SYS_FSL_DCSR_DDR3_ADDR"
Changed in v2:
	Update the patch commit message.
