[PATCH v3 0/6] Add SE HMBSC board support

SE HMIBSC board is based on Qcom APQ8016 SoC. One of the major difference from db410c is serial port where HMIBSC board uses UART1 as the debug console with an RS232 port, patch #2 - #5 adds corresponding driver support.
Patch #6 adds main HMIBSC board specific bits, features: - Qualcomm Snapdragon 410C SoC - APQ8016 (4xCortex A53, Adreno 306) - 2GiB RAM - 64GiB eMMC, SD slot - WiFi and Bluetooth - 2x Host, 1x Device USB port - HDMI - Discrete TPM2 chip over SPI
Features enabled in U-Boot: - RAUC updates (refer [2] for more details) - Environment protection - USB based ethernet adaptors
Feedback is very much welcome.
Changes in v3: - Rebased on top of qcom-next [1]. - Collected some review tags. - Incorporated misc. comments from Caleb and Stephen. - Split patch#4 as requested. - Linux HMIBSC board DTS has already been reviewed here [3], I have incorporated that for U-Boot too.
Changes in v2: - Rebased on top on qcom-next [1]. - Added patch#1 as a fix for generic qcom board support. - Added patch#4 to enable driving GPIO pins based on pinctrl configuration. This replaces the custom GPIO configuration. - Added proper DTS file for HMIBSC board based on Linux DT pattern. - Merged board support patches into a single patch#5.

Enabling LINUX_KERNEL_IMAGE_HEADER by default doesn't allow ENABLE_ARM_SOC_BOOT0_HOOK to work properly on db410c when U-Boot is loaded as a first stage bootloader. It leads to secondary CPUs bringup failure and later causing the Linux kernel to freeze.
So fix it via selectively enabling LINUX_KERNEL_IMAGE_HEADER where it's actually required.

I don't think this is a big deal but this patch would be a bit easier to skim over if you move the (unmodified?) import of the Linux apq8016-schneider-hmibsc.dts to a separate patch with a clear note in the commit message
- where it comes from (link to Linux patch), and - that it can be removed again with a future update of the upstream DTs in U-Boot (once it is applied upstream at least).
You kind of have that information in the cover letter but I think it would be good to have it in the commit message.

The "text-based environment" [1] is preferred nowadays, i.e. defining these inside board/schneider/hmibsc/hmibsc.env instead (similar to how DB410c has its environment defined in board/qualcomm/dragonboard410c/dragonboard410c.env). This should also avoid all the crazy escaping to encode it as C string. :D
However, I suspect that right now it would attempt to load this file from board/qualcomm/hmibsc/hmibsc.env since you do not seem to have CONFIG_SYS_VENDOR set correctly. It looks like Caleb removed the option to customize CONFIG_SYS_VENDOR in commit 059d526af312 ("mach-snapdragon: generalise board support"). It might be easiest to add a prompt in arch/arm/mach-snapdragon/Kconfig to allow changing it (similar to CONFIG_SYS_BOARD).
Thanks, Stephan

- USB based ethernet adaptors
Signed-off-by: Sumit Garg sumit.garg@linaro.org
I don't think this is a big deal but this patch would be a bit easier to skim over if you move the (unmodified?) import of the Linux apq8016-schneider-hmibsc.dts to a separate patch with a clear note in the commit message
- where it comes from (link to Linux patch), and
- that it can be removed again with a future update of the upstream DTs in U-Boot (once it is applied upstream at least).
You kind of have that information in the cover letter but I think it would be good to have it in the commit message.
Although the general practice in U-Boot is to have the board DTS file submitted along with board code, if it makes review easier via separating the unmodified import of the board DTS file then I can do that.

The "text-based environment" [1] is preferred nowadays, i.e. defining these inside board/schneider/hmibsc/hmibsc.env instead (similar to how DB410c has its environment defined in board/qualcomm/dragonboard410c/dragonboard410c.env). This should also avoid all the crazy escaping to encode it as C string. :D
That makes sense, I will convert to that.
However, I suspect that right now it would attempt to load this file from board/qualcomm/hmibsc/hmibsc.env since you do not seem to have CONFIG_SYS_VENDOR set correctly. It looks like Caleb removed the option to customize CONFIG_SYS_VENDOR in commit 059d526af312 ("mach-snapdragon: generalise board support"). It might be easiest to add a prompt in arch/arm/mach-snapdragon/Kconfig to allow changing it (similar to CONFIG_SYS_BOARD).
Although the restriction for Qualcomm being the only vendor for boards based on snapdragon SoCs shouldn't be added in the first place but since that patch did a lot of things in one go made its review harder. However, we can always fix it which I will do for the next version.

Given that in a few cycles we intend to drop the DTS you're adding here, having a commit we can just revert will make that much simpler.

CONFIG_DEFAULT_ENV_FILE can be set relative to the source tree root, so you can put your .env file anywhere you like and specify the full path.
I'm fine with allowing CONFIG_SYS_VENDOR to be overriden in the same way CONFIG_SYS_BOARD can be.
