PATCH v2 1/1 configs/stm32f4xx: use kernel version 4.11

Hello,

Quoted 7 lines · Christophe PRIOUZEAU

Linux kernel support the two stm32f4 discovery board since kernel 4.5 (stm32f429i-disco and stm32f469i-disco).

Use last kernel supported on buildroot for stm32f429 and stm32f469 board.

Could you please read entirely the review I did on your first version? It seems like you fixed only the issue that was mentioned at the top of my review, and didn't scroll through the entire e-mail.

Best regards,

Sorry, for the second revision which are not complete, I push a new one.

A little question about the kernel strategy on buildroot.

Do you prefer to use a specific kernel version or we can point on latest kernel (supported by buildroot if you don't apply patch on it) ?

Regards

Christophe

PATCH v2 1/1 configs/stm32f4xx: use kernel version 4.11

Hello,

I don't know how you have configured your Thunderbird, but the plain text version of the e-mails is bogus, as Thunderbird does not quote the text you're replying to. Could you try to fix your Thunderbird configuration? This will make your e-mail replies "acceptable" for open-source related mailing lists.

Great, thanks.

Our policy is to use a specific/fixed kernel and bootloader version in our defconfig, that we know has been tested by the contributor adding/updating the defconfig. That's exactly why I asked you to point to 4.11 specifically rather than just use the "latest kernel" option.

Thanks!

+There is no reason to override the kernel's default init= value, as

+used. Since stm32 is often used with a minimal bootloader
+(afboot-stm32) that doesn't provide any mechanism to override the DTB,

+Subject: [PATCH] ARM: stm32f249-disco: don't force init= in /chosen/bootargs
+
+There is no reason to override the kernel's default init= value, as
+this breaks userspace that assumes the kernel default of /init is
+used. Since stm32 is often used with a minimal bootloader
+(afboot-stm32) that doesn't provide any mechanism to override the DTB,
+we need to adjust the kernel command line in the Device Tree source.

-Rather than duplicate a defconfig for each difference

-Subject: [PATCH] ARM: configs: Add new config fragment to change RAM start
- point
-
-Rather than duplicate a defconfig for each difference
-between platforms, we can choose to pick a basic defconfig and -manipulate it at run-time using config fragments. Here we're -adding a new fragment to over-ride the RAM start point to 0x0.

Changes v1 -> v2:
- change the commit header (suggested by Thomas)
Changes v2 -> v3
- use LINUX_KERNEL_CUSTOM_VERSION_VALUE instead ofLINUX_KERNEL_LATEST_VERSION (suggested by Thomas)
Changes v3 -> v4
- use linux header of kernel 4.11 (suggested by Thomas)

Applied to master, thanks a lot!

Thomas
