[U-Boot] [PATCH] imx51:Add support basic boot code of freescale imx51 bbg board

This patch just supports boot into u-boot from mmc or spi-nor flash. It just implements console, iomux and clock. There are no ethernet, nor-flash, mmc or other peripheral drivers.

This patch just supports boot into u-boot from mmc or spi-nor flash. It just implements console, iomux and clock. There are no ethernet, nor-flash, mmc or other peripheral drivers.

Hmm... the comment in the code for mxc_request_iomux() reads:
* Request ownership for an IO pin. This function has to be the first one * being called before that pin is used. The caller has to check the * return value to make sure it returns 0.
I do not see any such checks in your code?
Either they are missing here, or the whole mxc_request_iomux() is not needed at all.

Does this board really need a specific linker script? Can we not use a generic one for all (or most of the) i.MX51 boards?

Is there any special reason for the "__" pat in all these names? You are aware that this has a special meaning in standard conforming C code, aren't you?
Please also add comments what all these functions are doing.
Hey, and add comments what the code is doing. It's not exactly obvious to me.

- reg = __raw_readl(MXC_CCM_CBCDR);
- if (reg & MXC_CCM_CBCDR_PERIPH_CLK_SEL) {
reg = __raw_readl(MXC_CCM_CBCMR);
switch ((reg & MXC_CCM_CBCMR_PERIPH_CLK_SEL_MASK) >>

case 0:
return __decode_pll(PLL1_CLK, CONFIG_MX51_HCLK_FREQ);

default:
return 0;
}
- }
- return __decode_pll(PLL2_CLK, CONFIG_MX51_HCLK_FREQ);
In such cases it's better to turn around the logig, i. e. write:
if ((reg & MXC_CCM_CBCDR_PERIPH_CLK_SEL) == 0) return __decode_pll(PLL2_CLK, CONFIG_MX51_HCLK_FREQ); reg = __raw_readl(MXC_CCM_CBCMR); switch ((reg & MXC_CCM_CBCMR_PERIPH_CLK_SEL_MASK) >> MXC_CCM_CBCMR_PERIPH_CLK_SEL_OFFSET) { case 0: return __decode_pll(PLL1_CLK, CONFIG_MX51_HCLK_FREQ); case 1: return __decode_pll(PLL3_CLK, CONFIG_MX51_HCLK_FREQ); default: return 0; } /* NOTREACHED */
You see? Less indentation = easier to read.

Dear wolfgang, I almost fixed all of your comments. By some of them I can not fix them now. 1) Copyright block. It defined freescale other team. I can not change them directly. 2) iomux module can not use C structure to access registers. Because register has encoded in to pin definition. When I tested the new code on target board, I will send out to review again. Best Regards Fred

Dear Fred Fan,

This patch just supports boot into u-boot from mmc or spi-nor flash. It just implements console, iomux and clock. There are no ethernet, nor-flash, mmc or other peripheral drivers.

I read: "The ROM code will ... load ... initial hardware" ? [Fred] MX family soc has internal boot mode. At this mode, the rom code in soc will
read the setting array to initial hardware.
Something seems to be missing, or do you mean s/initial/initialize/ ?

It seems this is a iMX51 specific thing, right? Then please make this clear in the name oif the file and the macro names. "FLASH_HEADER" or "flash_head" is way too generic. [Fred] It is coming from freescale spec. It is the header of boot image for freescale internal boot mode.

How much of this is really board specific code, or how much of it should be moved to the CPU directory instead? [Fred] Although freescale's boards use same configuration about M4IF, AIPS or others.

Hmm... the comment in the code for mxc_request_iomux() reads:
- Request ownership for an IO pin. This function has to be the first one
- being called before that pin is used. The caller has to check the
- return value to make sure it returns 0.
I do not see any such checks in your code?
Either they are missing here, or the whole mxc_request_iomux() is not needed at all. [Fred] OK. I changed these functions to non return function.
Because boot load is not dynamic active or modules, there are no modules with muxed pins.

Dear Fred Fan,
In message 2f495dc80912010844h6b4aa1e4i4588f808384b6272@mail.gmail.com you wrote:
I almost fixed all of your comments.
By some of them I can not fix them now.
- Copyright block. It defined freescale other team. I can not change them
directly.
I see. We will have to wait for this change, then.
- iomux module can not use C structure to access registers. Because
register has encoded in to pin definition.
I don't understand this statement. Why do you think this cannot be done with C structs and I/O accessors?
When I tested the new code on target board, I will send out to review again.
I'm looking forward to get this mainlined, but please fix all issues first. Thanks.
Best regards,
Wolfgang Denk

Hi Fred,
I have already tested your patch on the babbage2 board and I would ask you about the status. The boot loader does not start (I have tried flashing the SPI NOR, and this seems ok. The code seems loaded from the flash) but the board hangs. With the debugger seems that it hangs in the init_clock assemby routine in lowlevel_init.S.
Have you seen the same behavior or do you think it depens on my environment ?
Regards, Stefano

HI Stefano Babic, Sorry, I just see your and wolfgang's mail. In this days, I am prepare new soc's kernel MSL code. When I just finished my coding, I have same issue too. But during I identify this issue, the issue is disappeared. I does not change lowlevel_init.s. Maybe I removed some definitions of clock register. I will check it ASAP. Best Regard Fred

Hi Fred,
do not worry, I could find where the problem is located. I started from the IMX51 BSP, changing code to adapt for the u-boot top of tree, and then I applied all changes you sent in your patchset. So I could check step by step where I had to look.
I do not find any issue in the cpu/mx51/clock.c and in the clock definitions, that you rearranged after the first review, so in this file everything seems ok ;)
Definitely I checked with the debugger that the problem arises in the first initialization of the clock registers in lowlevel_init.S (after the init_clock label). I replaced the file with the one I found in the BSP and the board runs now flawlessly.
I have already removed the flashHeader.S, adding a new image format to support the i.MX51 processor and its DCD table.
I have opened another issue, too. I have seen that the name "babbage" is quite disappeared and on the Freescale's website this board is named now "mx51evk". I know you have already changed the name of the board, but I think the name "babbage" can confuse. Better should be to rename the board with the name we find in the official documentation. I know you already did this job, I can only volunteer myself to do that...
What do you think if I take over the job and I will resend all patches to the ML ? In this way I can easier integrate my changes, if you agree. Should be ok for you ?
Best regards, Stefano Babic

This patch just supports boot into u-boot from mmc or spi-nor flash. It just implements console, iomux and clock. There are no ethernet, nor-flash, mmc or other peripheral drivers.
