Partially updated without addition of choice for the time being. I will see for the choice / endchoice section, which will probably will make the PR bigger in order to also update existing Kconfig.default / conf files. |
|
This idea of this PR would be to avoid having to prepare linker scripts such as boards/st/stm32h747i_disco/dc_ram.ld, boards/st/stm32h757i_eval/dc_ram.ld, boards/st/stm32h7b3i_dk/dc_ram.ld for all boards, which also do not give flexibility on which section to use. |

Update following @JarmouniA proposal for config name and added depend !... to avoid possibility to have both mode enabled at the same time. I only put it on one side (ZEPHYR_REGION depends on !CUSTOM_SECTION) to avoid dependency loop. |
|
@erwango should I also remove the existing stm32 lvgl_buf related linker scripts and update the related conf to make usage of this new option instead ? |
+1 from me, since this should ensure it is built during CI and shows users looking for refrence usage how to do it. |
Yeah, go ahead. Let's clean this up right away. |

Thanks @JarmouniA, updates applied. First push before rebase to be able to see updates. |
Allow selection of a custom section for memory-poll and / or VDB based on zephyr memory-regions. This takes advantages that zephyr,memory-region automatically have sections being created, hence allowing to easily indicate into which memory-region to store data.

Following introduction of LV_Z_MEMORY_POOL_ZEPHYR_REGION and LV_Z_VDB_ZEPHYR_REGION, remove the usage of the option LV_Z_VDB_CUSTOM_SECTION and the related linker scripts for STM32 boards & shields. Signed-off-by: Alain Volmat <[email protected]>
