feat(plat/st): use FIP to load images BL2 still uses the STM32 header binary format to be loaded from ROM code. BL32 and BL33 and their respective device tree files are now put together in a FIP file. One DTB is created for each BL. To reduce their sizes, 2 new dtsi file are in charge of removing useless nodes for a given BL. This is done because BL2 and BL32 share the same device tree files base. The previous way of booting is still available, the compilation flag STM32MP_USE_STM32IMAGE has to be set to 1 in the make command. Some files are duplicated and their names modified with _stm32_ to avoid too much switches in the code.

feat(stm32mp1-fdts): use /omit-if-no-ref/ for pins nodes With the /omit-if-no-ref/ keyword in DT, the non-referenced nodes are just removed. This allows reducing the size of device tree blobs. Setting it before pins node allows a size reduction of more than 2kB. The corresponding nodes can also be removed from BL2 and BL32 DT overlays.

fix(stm32mp1-fdts): move /omit-if-no-ref/ to overlay files To keep (as much as possible) alignment with Linux DT, move the /omit-if-no-ref/ keywords to DT overlay files (fdts/stm32mp1*-bl*.dtsi). This also ease checks for ST tools. Signed-off-by: Yann Gautier <yann.gautier@foss.st.com> Change-Id: Ib467a6b65f05a84c9678799ad32e1820249b4ed1

fix(stm32mp15-fdts): use /omit-if-no-ref/ for spi and i2c Use /omit-if-no-ref/ keyword in DT to remove extra device nodes only when they are not used / not referenced. If the board device tree only defines subnodes, dtc does not consider it as usage, you have to specifically mention device's phandle, e.g.: \ { i2c6-phandle = <&i2c6>; }; or in aliases section aliases { i2c6 = &i2c6; }; Signed-off-by: Vyacheslav Yurkov <uvv.mail@gmail.com> Change-Id: I431ecd93576f97fd021d82d23b93c659fc8f26b8
