| Summary | 0005985: On fsimx8mm, add old device tree names for compatibility | ||||
| Description | Old BOARD-CFG variants used the name PicoCoreMX8MM for PicoCoreMX8MM-LPDDR4 and PicoCoreMX8MX for PicoCoreMX8MM-DDR3L. These names are used to determine the dtb device tree name for U-Boot. For updating from old NBoot/U-Boot combinations to new combinations, we need to update U-Boot first and then restart, because only a new U-Boot knows how to store a new NBoot image with all the new NBoot features. However if the new U-Boot only has dtb device tree files with the new names appended, then the old NBoot with the old dtb names in its BOARD-CFGs will not find the dtb in the new U-Boot and fails to start U-Boot. So for now, also add copies of the device trees under the old names. This increases the U-Boot size, but there is no other way. After a while we can drop the old names again. - Create symbolic links picocoremx8mm.dts and picocoremx8mx.dts that point to picocremx8mm-lpddr4.dts and picocoremx8mm-ddr3l.dts respectively. - Add the old filenames to arch/arm/dts/Makefile. - In fsimx8mm_defconfig, also include the old filenames in the list of added dtb files. | ||||
