PATCH v4 1/9 configs: imx6: Don't define USDHC2_BASE_ADDR

From: Jagan Teki <[email protected]>

USDHC base address will assigned by SPL using fsl_esdhc_initialize and u-boot with devicetree, hence no remove base address assignment in config files.

I have seen that a lot of files slipped into mainline, and I have myself not paid enough attention befeore (see your imx6ul-geam-kit.dts for example).

But we moved some years ago to SPDX-License-Identifier. Other DTS files are using this as well without copying the whole license. Could you do this here, too ? It would be also nice if you plan to fix this for all Engicam's boards, thanks !

I have seen that a lot of files slipped into mainline, and I have myself not paid enough attention befeore (see your imx6ul-geam-kit.dts for example).

Quoted 4 lines

But we moved some years ago to SPDX-License-Identifier. Other DTS files are using this as well without copying the whole license. Could you do this here, too ? It would be also nice if you plan to fix this for all Engicam's boards, thanks !

Yes for boards, I will prepare patch.

For devicetress, since the base dtsi files copied from Linux, we keep the license as it is. I am not sure all other dts(i) files use the SPDX-License-Identifier. example imx6sll-evk, imx6ull-14x14-evk and all sunxi .

Should you not add the DTS files ?

Good idea, I will add.

+How to use U-Boot on Engicam Is.IoT MX6UL Starter Kit:
+-----------------------------------------------------
+
+- Configure U-Boot for Engicam Is.IoT MX6UL
+
+$ make mrproper
+$ make imx6ul_isiot_mmc_defconfig
+$ make
+
+This will generate the SPL image called SPL and the u-boot-dtb.img.
+
+- Flash the SPL image into the micro SD card:
+
+sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
+
+- Flash the u-boot-dtb.img image into the micro SD card:
+
+sudo dd if=u-boot-dtb.img of=/dev/mmcblk0 bs=1k seek=69; sync
+
+- Jumper settings:
+
+MMC Boot: JM3 Closed
+
+- Connect the Serial cable between the Starter Kit and the PC for the console.
+(J28 is the Linux Serial console connector)
+
+- Insert the micro SD card in the board, power it up and U-Boot messages should
+come up.

Just a mention here: why do you activate all clocks instead of just what you really need ?

May be yes, but it's better to have full clock initialization so-that nothing broke during SPL runtime.

thanks!

But we moved some years ago to SPDX-License-Identifier. Other DTS files are using this as well without copying the whole license. Could you do this here, too ? It would be also nice if you plan to fix this for all Engicam's boards, thanks !

Quoted 6 lines

Yes for boards, I will prepare patch.

For devicetress, since the base dtsi files copied from Linux, we keep the license as it is. I am not sure all other dts(i) files use the SPDX-License-Identifier. example imx6sll-evk, imx6ull-14x14-evk and all sunxi .

It is true that some files slipped into mainline copying again all license stuff - and several files ported from Linux was adjusting for SPDX.

Tom, what do you think ?

Should you not add the DTS files ?

Good idea, I will add.

+How to use U-Boot on Engicam Is.IoT MX6UL Starter Kit:
+-----------------------------------------------------
+
+- Configure U-Boot for Engicam Is.IoT MX6UL
+
+$ make mrproper
+$ make imx6ul_isiot_mmc_defconfig
+$ make
+
+This will generate the SPL image called SPL and the u-boot-dtb.img.
+
+- Flash the SPL image into the micro SD card:
+
+sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
+
+- Flash the u-boot-dtb.img image into the micro SD card:
+
+sudo dd if=u-boot-dtb.img of=/dev/mmcblk0 bs=1k seek=69; sync
+
+- Jumper settings:
+
+MMC Boot: JM3 Closed
+
+- Connect the Serial cable between the Starter Kit and the PC for the console.
+(J28 is the Linux Serial console connector)
+
+- Insert the micro SD card in the board, power it up and U-Boot messages should
+come up.

Just a mention here: why do you activate all clocks instead of just what you really need ?

Quoted 2 lines

May be yes, but it's better to have full clock initialization so-that nothing broke during SPL runtime.

You are the board maintainer, and it is your decision. Anyway, clocks are not disable in u-boot, and they can remain on in Linux, because they are set just if needed. Some kernels had disabled in the past for some platform (I know OMAP3) all not required clocks, but this was in the era before DT. Kernel just supposes that nothing is set.

I have seen that a lot of files slipped into mainline, and I have myself not paid enough attention befeore (see your imx6ul-geam-kit.dts for example).

Quoted 4 lines

But we moved some years ago to SPDX-License-Identifier. Other DTS files are using this as well without copying the whole license. Could you do this here, too ? It would be also nice if you plan to fix this for all Engicam's boards, thanks !

Quoted 6 lines

Yes for boards, I will prepare patch.

For devicetress, since the base dtsi files copied from Linux, we keep the license as it is. I am not sure all other dts(i) files use the SPDX-License-Identifier. example imx6sll-evk, imx6ull-14x14-evk and all sunxi .

It is true that some files slipped into mainline copying again all license stuff - and several files ported from Linux was adjusting for SPDX.

Tom, what do you think ?

Just a mention here: why do you activate all clocks instead of just what you really need ?

Quoted 2 lines

May be yes, but it's better to have full clock initialization so-that nothing broke during SPL runtime.

You are the board maintainer, and it is your decision. Anyway, clocks are not disable in u-boot, and they can remain on in Linux, because they are set just if needed. Some kernels had disabled in the past for some platform (I know OMAP3) all not required clocks, but this was in the era before DT. Kernel just supposes that nothing is set.

I agree with Stefano. Clocks part should clean up. We have done in the past for OMAP architecture

I have seen that a lot of files slipped into mainline, and I have myself not paid enough attention befeore (see your imx6ul-geam-kit.dts for example).

Quoted 4 lines

But we moved some years ago to SPDX-License-Identifier. Other DTS files are using this as well without copying the whole license. Could you do this here, too ? It would be also nice if you plan to fix this for all Engicam's boards, thanks !

Quoted 6 lines

Yes for boards, I will prepare patch.

For devicetress, since the base dtsi files copied from Linux, we keep the license as it is. I am not sure all other dts(i) files use the SPDX-License-Identifier. example imx6sll-evk, imx6ull-14x14-evk and all sunxi .

It is true that some files slipped into mainline copying again all license stuff - and several files ported from Linux was adjusting for SPDX.

Tom, what do you think ?

Just a mention here: why do you activate all clocks instead of just what you really need ?

Quoted 2 lines

May be yes, but it's better to have full clock initialization so-that nothing broke during SPL runtime.

You are the board maintainer, and it is your decision. Anyway, clocks are not disable in u-boot, and they can remain on in Linux, because they are set just if needed. Some kernels had disabled in the past for some platform (I know OMAP3) all not required clocks, but this was in the era before DT. Kernel just supposes that nothing is set.

Quoted 2 lines

I agree with Stefano. Clocks part should clean up. We have done in the past for OMAP architecture

I would like to go-ahead with these now, since many of i.MX(even other engicam) boards does the same. I will need to look into it and prepare patches for all.

thanks!

Just because I (or someone else) did not note this isuse in the past, it does not mean that this is a good reason to go on doing wrongly.

Fix this, and you will have time later to send patches for the other boards.

Best regards,
Stefano

But we moved some years ago to SPDX-License-Identifier. Other DTS files are using this as well without copying the whole license. Could you do this here, too ? It would be also nice if you plan to fix this for all Engicam's boards, thanks !

Yes for boards, I will prepare patch.

For devicetress, since the base dtsi files copied from Linux, we keep the license as it is. I am not sure all other dts(i) files use the SPDX-License-Identifier. example imx6sll-evk, imx6ull-14x14-evk and all sunxi .

Quoted 4 lines

It is true that some files slipped into mainline copying again all license stuff - and several files ported from Linux was adjusting for SPDX.

Tom, what do you think ?

The DT files we copy from the kernel are the exception to the rule, they should just keep the usual full license header they come in with. This is even "easier" to do now, given that we can append any U-Boot centric bits into a -uboot.dtsi file and keep the upstream DT files unmodified entirely.
