Subject: Compressed DTB - builtin DTB
Date: Thu, 13 Oct 2016 12:32:31 +0200 [thread overview]
Message-ID: <03214122-b05b-fc45-1e32-ad2832ca36d3@systec-electronic.com> (raw)
Hello,
I'm currently porting our board support to device tree. Currently, I
don't use multi-PBL, but include the device tree via CONFIG_BUILTIN_DTB.
This works, but the DTB seems to be included twice in the image: once as
plain DTB and once as compressed DTB. I think this isn't intended this way.
Extract from System.map:
87e82b80 R __dtb_imx35_systec_hmi_start
87e82b80 R __dtb_start
87e8501c R __dtb_imx35_systec_hmi_end
87e85020 R __dtb_z_imx35_systec_hmi_start
87e85ad0 R __dtb_z_imx35_systec_hmi_end
87e85b00 B __bss_start
87e85b00 R __dtb_end
Just using the compressed DTB would be really good. Because it makes the
image much smaller. However, how should that be done? The extract code
might be simple. But I don't have an idea how to let the linker select
the right version.
Thanks for any kind of support,
Daniel
