The XEA board now has several HW revisions for SoM boards. This patch provides support for reading this revision ID values in early u-boot proper as production devices boot via falcon boot with correct DTB flashed at production (so there is no need to alter SPL). Additionally, the maximal SPL size (~55KiB) constraint is not allowing having even simplified FIT support in it. As a result it was necessary to handle reading GPIOs values solely in u-boot proper as one configuration (i.e. 'single binary' - imx28_xea_sb_defconfig) is not using SPL framework. Moreover, the 'board_som_rev' environment variable will be used to point correct configuration from the Linux FIT file. Additionally, as now XEA has its second HW revision - this information is printed when u-boot proper starts. Signed-off-by: Lukasz Majewski <lukma@denx.de> |
