Fix Version: 6.0.0.7
Severity: Standard
Applicable for: Wind River Linux 6
Component/s: BSP
The "/include/ "fsl/p2041si-pre.dtsi" has /dts-v1/;
Hence we could not define /memreserve/ inside p2041rdb.dts as it does contains "/include/ "fsl/p2041si-pre.dtsi" which takes precedence on p2041rdb.dts:
The rule is that the custom setting should be between /dts-v1/; and other includes .
They way the p2041rdb.dts file is organized for freescale is wrong
The p2041rdb.dts has
/include/ "fsl/p2041si-pre.dtsi"
/ {
model = "fsl,P2041RDB";
compatible = "fsl,P2041RDB";
#address-cells = <2>;
#size-cells = <2>;
interrupt-parent = <&mpic>;
--> The ability to specify the memreserve should be at board level
- Add memreserve in p2041si-pre.dtsi.
1. configure project for p2041 target:
- configure --with-ccache-size=10G --with-ccache-dir=/opt/tmp/ccache --enable-parallel-pkgbuilds=4 --enable-jobs=4 --enable-ccache=yes --with-sstate-dir=/opt/tmp/sstate --enable-board=fsl-e500mc --enable-kernel=standard --enable-rootfs=glibc_std --enable-reconfig --enable-rm-oldimgs=yes --with-template=feature/initramfs --with-rcpl-version=0005
2. modify
./bitbake_build/tmp/work/fsl_e500mc-wrs-linux/linux-windriver/3.10-r0/linux/arch/powerpc/boot/dts/p2041rdb.dts
to reserve RAM memory by adding at the top of p2041rdb.dts :
/memreserve/ 0x40000000 0x04000000; /* for fxbcm driver */
3. The compilation for fsl-e500mc kernel should fail with syntax error.
