Subject: [PATCH] LF-789-1 Revert "scripts: Makefile: Enable creation of
|
|
_symbols_ DT node for overlays"
|
|
|
|
This reverts commit 432071b7a106060fa4e451e10249cef021af0b7c.
|
|
|
|
commit: 432071b7a106 scripts: Makefile: Enable creation of _symbols_ DT node for overlays
|
|
changes the common Makefile and force creation of __symbols__ node on all platforms.
|
|
|
|
This is not good and not acceptible under some cases due to this change will increase
|
|
the final DTB size a lot and bring big impact for others who does not need creation
|
|
of _symbols_ DT node for overlays.For example, on i.MX OP-TEE, the maxsize of DT is 1MB,
|
|
this patch will break some of the i.MX6/i.MX7 boards to boot with OP-TEE enabled.
|
|
|
|
BTW, community has the similar patch but rejected. The following post discuss about this:
|
|
https://lore.kernel.org/patchwork/patch/821645/
|
|
|
|
For specifc plaform/board which need the creation of _symbols_ DT node for overlays, user can
|
|
define DTC_FLAGS_target either trough dtc build command line(#1) or with board specific Makefile(#2)
|
|
|
|
For example:#1
|
|
|
|
make DTC_FLAGS_fsl-ls1028a-qds=-@ freescale/fsl-ls1028a-qds.dtb
|
|
|
|
For example:#2
