The Vybrid devices are a family of Freescale's latest Dual Single Core offering with ARM Cortex A5 and CM4 based processors for Advanced Connected Radio, Entry Infotainment, and Cluster as well as high end industrial and general purpose applications.

This patch adds vybrid CPU support.

Hi Alison,

first: I agree with Fabio's comments - I try to no repeat his comments here.

[Alison Wang] Thanks.

I would like to understand there common code should be put. As you can see, for i.MX there is a imx_common directory that is valid across ARM-Core.

[Alison Wang] I'm trying to align the soc with i.mx platform and will use i.MX's imx_common directory in the next version. But there are still some issues for sharing the I.MX platform,

1. i.mx family uses GPT in timer.c. VF600 doesn't have GPT but a Periodic Interrupt Timer(PIT) which I think is totally different with GPT. Too much ifdef in the timer.c seems unacceptable. So I plan to modify the Makefile and add a pit.c file in imx_common directory for the timer on this Vybrid platform, How do you think about this idea? Thanks.

2. The SRC_SRSR register definition on VF600 is different with i.MX. To reuse the get_reset_cause() function in cpu.c, some platform related ifdef will be introduced. For example: #ifdef CONFIG_MVF600 case 0x00080: return "EXTERNAL RESET"; #endif

Does this kind of ifdef acceptable? Thanks.

3. If sharing the cpu.c with I.MX, The cpu information printed will be "CPU: Freescale i.MX%s". As the Vybrid is not really the I.MX serials soc, I think the description should be Vybrid. Any suggestion for how to separate this in the cpu.c? Thanks a lot.

4. There are also some differences with the I.MX for the IOMUX. On the I.MX, there are separate registers for mux_mode and pin_ctrl, but on Vybrid, this two registers are merged into one 32bit register. I'm discussing this with Liu Hui on another mailchain. Any good suggestions? Thanks a lot.

I think after the main issues above got fixed, the Vybrid platform can be aligned with I.MX smoothly.

I do not think we need a new rule only to have a new name. u-boot.imx had exactly the same rule here, but we decided in the past that some specific SOC rules should belong to the SOC (=CPU) directory without touching the main Makefile. The same rule you put here you can find into arch/arm/imx-common/Makefile. If the vybrid has nothing to do with imx_common, the rule to generate the image should go into the vybrid/ directory.

Mainly I disagree to add a new name if we do not get a new image. The list you see contains different images, not different names. As far as I can see, u-boot.vybrid has the same structure and is built in the same way as u-boot.imx.

I do not think it is a good idea to pad with dummy data only to output it later. I think it is better to use straightforward the same mechanism we have for all other SOC, that is:

• add defines for each cause (WDOG/POR...), better check if we can reuse

/ factorize common values.

• implement get_reset_cause() in the same way (check implementation for

MX35 / MX5 / MX6..). It is much more readable.

[Alison Wang] The name of the registers are the same, such as ccm_caccr, ccm_ccsr. But the definitions of the registers are different between vybrid and i.mx6 platforms.

Why cannot we do this in C code ? You introduce a lot of CONFIS_SYS_CLKCTL_ in the board configuration file. This can be done in board code, for example in board_early_init_f(), without constrain all boards to set all of this stuff, but only what is required.

[Alison Wang] Agree. I will move these configurations into board_early_init_f() in the next version patches.

You use inconsistently doxygen comments. As I remember, there is no decision to use it in the project, so please remove the meta chars.

[Alison Wang] Agree.

I prefer you use the same convention we have for other Freescale's SOC, that is PORT starts from 1 and not from zero. Check if you can use the macros already set for MX% / MX6.

[Alison Wang] Agree.

No, we drop this. Set instead CONFIG_MACH_TYPE in your board configuration file.

[Alison Wang] Agree. I will set in board configuration file in the next version patches.

Thanks a lot!

u-boot upstream recommend that we use the structure access not the base + offset, please consider to change to the u-boot upstream style.

What the code does here, disable-wdog, right? IMHO, - We can't disable the WDG if it already enabled. - The macro name, setup_wdog will confuse others, since the reader may guess Will setup(enable) the WDG.

But I guess this code is useless, you can remove it.

Vybrid is the SoC name and the board name is vf600, right?

Then you should add:

board/freescale/vf600

Also, please copy Stefano Babic in your future patches, as he is the U-boot imx maintainer.

This patch should be the last of the series.

You add the board support here, but ethernet, serial, esdhc support comes later in the patch series.

Please add an entry to MAINTAINERS file.

You introduced CONFIG_SYS_UBOOT_IN_GPURAM here and it would be nice to add an entry into README explaining what it means.

Can't you use the standard method?

CONFIG_QUAD_SPI does not exist in U-boot. Can't you re-use an existing SPI config option?

This function should basically return the card detect status, please setup the IOMUX in another place.

•   ret = 1;
  

•   return ret;
  

In this board you assume that the SD card is always present, right?

You could remove the 'ret' variable.

Do we really need two configs? Can't we have just one?
