[U-Boot] [PATCH] arm: rmobile: kzm9g: Adjust hardware setting in lowlevel_init.S

[Tetsuyuki Kobayashi]

This patch depends on
 Nobuhiro Iwamatsu's arm: rmobile: Add supoprt for KMC KZM-A9-GT board
 Tetsuyuki Kobayashi's arm: rmobile: kzm9g: Modify sdram area


Adjust hardware setting in lowlevel_init.S.
After this patch U-boot can boot Linux kernel (without DTB) on KZM-A9-GT board successfully.

Seems like a series to me -- you should post it as such, with patches
numbered 1/N, 2/N etc. Should be easy as you probably already have them
as a series of commits above master; git format-patch should generate
the mails alright.

OK. I am studying git format-patch and git send-email.

[U-Boot] [PATCH 0/3] arm: rmobile: kzm9g: enable booting Linux kernel

[Tetsuyuki Kobayashi]

Hello, Iwamatu-san

I rebased u-boot-sh.git arm/rmobile branch and reworked my patches.
After this patch set, LTSI kernel can boot on KZM-A9-GT board.

But I found it is not stable. It needs more work.

Applied to my rmobile repository. Thanks.
BTW, do you become a maintainer of kzm9g board?
If it becomes a maintainer, please send the patch to MAINTAINERS file.

Best regards,

OK.

Iwamatsu-san,
Now I have another patch for kzm9g.
So I will make updated patch series including 5 patches.

[U-Boot] [PATCH v3 0/6] arm: rmobile: kzm9g: enable booting Linux kernel

[Tetsuyuki Kobayshi]

From: Tetsuyuki Kobayashi <koba@kmckk.co.jp>

Hi, Iwamatsu-san

This is v3 patch set for kzm9g.
I add a patch for modifying bus controller setting for CS4.

After this patch set, LTSI kernel can boot on KZM-A9-GT board.
It seems stable as before.

[U-Boot] [PATCH v3 6/6] arm: rmobile: kzm9g: Modify bus controller setting for CS4

[Tetsuyuki Kobayshi]

From: Tetsuyuki Kobayashi <koba@kmckk.co.jp>

Problem:
Linux kernel hangs up when it write a file to NFS mounted directory.
Solution:
Modify bus controller setting for CS4, which connected smsc9221 ethernet
controller.

Detail:
Modify CS4BCR bit[29:28] (IWW[1:0]) from 00 to 11.
It inserts 4 idle cycles between Write-Read/Write-Write cycles.
Modify CS4WCR bit[18:16] (WW[2:0]) from 101 to 111
It specifies the number of cycles necessary for write access.
