Subject: [PATCH] arm64: zynqmp: accept an absolute path for PMUFW_INIT_FILE
|
||
|
|
|
||
|
|
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
