If the user tries to change BUILD_BASE to put the build products outside the build tree the compile will fail due to hard coded assumptions that $BUILD_BASE is a relative path. Fix by using $(abspath $(BUILD_BASE)) to rationalize to an absolute path every time and remove the relative path assumptions. This patch also adds documentation that BUILD_BASE can be specified by the user.

"""
|
|
This script is invoked by Make system and generates secure partition makefile.
|
|
It expects platform provided secure partition layout file which contains list
|
|
of Secure Partition Images and Partition manifests(PM).
|
|
Layout file can exist outside of TF-A tree and the paths of Image and PM files
|
|
must be relative to it.
|
|
|
|
This script parses the layout file and generates a make file which updates
|
|
FDT_SOURCES, FIP_ARGS, CRT_ARGS and SPTOOL_ARGS which are used in later build
|
|
steps.
|
|
This script also gets SP "uuid" from parsing its PM and converting it to a
|
|
standard format.
|
|
|
|
param1: Generated mk file "sp_gen.mk"
|
|
param2: "SP_LAYOUT_FILE", json file containing platform provided information
|
|
param3: plat out directory
|
|
|
|
Generated "sp_gen.mk" file contains triplet of following information for each
|
|
Secure Partition entry
|
|
FDT_SOURCES += sp1.dts
|
|
SPTOOL_ARGS += -i sp1.bin:sp1.dtb -o sp1.pkg
|
|
FIP_ARGS += --blob uuid=XXXXX-XXX...,file=sp1.pkg
|
|
CRT_ARGS += --sp-pkg1 sp1.pkg
|
|
|
|
A typical SP_LAYOUT_FILE file will look like
|
|
{
|
|
"SP1" : {
|
|
"image": "sp1.bin",
|
|
"pm": "test/sp1.dts"
|
|
},
|
|

"SP2" : {
|

"image": "sp2.bin",
|

"pm": "test/sp2.dts"
