Dear All,
I am trying to minimize the u-boot and started to remove some features I don't need.
I tried to remove whole video & LCD support, but run into issue that stm32mp1.c has a large patch, that applies LCD automatic recognition and extern reference to panel drivers. I am using Kirkstone, but it is also in the patch for Scarthgap.
Patch: 0002-ARM-v2021.10-stm32mp-r1-BOARD.patch
stm32mp1.c:
extern U_BOOT_DRIVER(rm68200_panel);
extern U_BOOT_DRIVER(hx8394_panel);
(...)
Here are feature I'd like to disable, but removing i.e. VIDEO_LCD_xxx features gives me a compile error for missing extern reference to rm68200_panel.
CONFIG_CMD_ADC=y
CONFIG_STM32_ADC=y
CONFIG_FDT_SIMPLEFB=y
CONFIG_DM_VIDEO=y
CONFIG_BACKLIGHT_GPIO=y
CONFIG_VIDEO_LCD_ORISETECH_OTM8009A=y
CONFIG_VIDEO_LCD_RAYDIUM_RM68200=y
CONFIG_VIDEO_LCD_ROCKTECH_HX8394=y
CONFIG_VIDEO_STM32=y
CONFIG_VIDEO_STM32_DSI=y
I tried different things to remove, but neither works. Removing and/or modifing the whole patch is rather not worth the result, but maybe there is a better approach to this?
Thanks
Oskar
