The value of PMUFW_INIT_FILE is prefixed with "$(srctree)/", thus forcing it to be a relative path inside the U-Boot source tree. Since the PMUFW is a binary file generated outside of U-Boot, the PMUFW binary must be copied inside the U-Boot source tree before the build. This generates a few problems: * if the source tree is shared among different out-of-tree builds, they will pollute (and potentially corrupt) each other * the source tree cannot be read-only * any buildsystem must add a command to copy the PMUFW binary * putting an externally-generated binary in the source tree is ugly as hell Avoid these problems by accepting an absolute path for PMUFW_INIT_FILE. This would be as simple as removing the "$(srctree)/" prefix, but in order to keep backward compatibility we rather use the shell and readlink to get the absolute path even when starting from a relative path. Since 'readlink -f' produces an empty string if the file does not exist, we also add a check to ensure the file configured in PMUFW_INIT_FILE exists. Otherwise the build would exit successfully, but produce a boot.bin without PMUFW as if PMUFW_INIT_FILE were empty. Tested in the 12 possible combinations of: - PMUFW_INIT_FILE empty, relative, absolute, non-existing - building in-tree, in subdir, in other directory Signed-off-by: Luca Ceresoli <luca@lucaceresoli.net> Cc: Michal Simek <michal.simek@xilinx.com> Cc: Simon Glass <sjg@chromium.org> Cc: Emmanuel Vadot <manu@bidouilliste.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com> |
