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

OK. I am studying git format-patch and git send-email.
Hi,
I modified my rmobile git tree. Please rebase your local repository and resend this patch. Best regards, Nobuhiro

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.

OK.
Iwamatsu-san, Now I have another patch for kzm9g. So I will make updated patch series including 5 patches. (previous 3 patches + MAINTAINERS + new patch)
Hi, Iwamatsu-san
I made v2 patch set for kzm9g. Please revert my previous 3 patches and apply this patch set.
After this patch set, LTSI kernel can boot on KZM-A9-GT board. It seems stable as before.

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.

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 01. Modify CS4BCR bit[20:19] (IWRRD[1:0]) from 00 to 01. Modify CS4BCR bit[17:16] (IWRRS[1:0]) from 00 to 01. Modify CS4WCR bit[27:26] (WSW[1:0]) from 10 to 11 Modify CS4WCR bit[25:24] (WHW[1:0]) from 01 to 10 Modify CS4WCR bit[18:16] (WW[2:0]) from 101 to 111 Modify CS4WCR bit[13:11] (SW[2:0]) from 010 to 011 Modify CS4WCR bit[10:7] (WR[3:0]) from 1000 to 1011
