Subject: [PATCH v4 09/13] binman: Support packaging U-Boot for scenarios like OF_BOARD or OF_PRIOR_STAGE
Date: Mon, 10 May 2021 14:58:33 +0800 [thread overview]
Message-ID: <20210510065837.2008556-10-bmeng.cn@gmail.com> (raw)
In-Reply-To: <20210510065837.2008556-1-bmeng.cn@gmail.com>
For scenarios like OF_BOARD or OF_PRIOR_STAGE, no device tree blob is
provided in the U-Boot build phase hence the binman node information
is not available. In order to support such use case, a new Kconfig
option BINMAN_STANDALONE_FDT is introduced, to tell the build system
that a device tree blob containing binman node is explicitly required
when using binman to package U-Boot.

Changes in v4:
- update the makefile dependency on u-boot.img instead of u-boot.bin
Changes in v3:
- rename the Kconfig option name to BINMAN_STANDALONE_FDT
- make BINMAN_STANDALONE_FDT default y for OF_BOARD as well
- reword the Kconfig option help message a little bit
Changes in v2:
- new patch: "binman: Support packaging U-Boot for scenarios like OF_PRIOR_STAGE"
