[PATCH v2] powerpc: dts: Build devicetrees of enabled platforms
Posted by J. Neuschäfer via B4 Relay 1 month ago 
From: "J. Neuschäfer" <j.ne@posteo.net>

Follow the same approach as other architectures such as Arm or RISC-V,
and build devicetrees based on platforms selected in Kconfig. This makes
it unnecessary to use CONFIG_OF_ALL_DTBS on PowerPC in order to build
DTB files.

This makes it easier to use other build and test infrastructure such as
`make dtbs_check`, and is a first step towards generating FIT images
that include all the relevant DTBs with `make image.fit`.

Signed-off-by: J. Neuschäfer <j.ne@posteo.net>

Changes in v2:
- Use "dtb-$(FOO) += foo.dtb" format on every line, avoid backslashes
  (suggested by Geert Uytterhoeven)
- Link to v1: https://lore.kernel.org/r/20260119-mpc83xx-dtb-v1-1-522f841290bf@posteo.net

Why so many lines ? You should be able to fit approximaly four per line,

dtb-$(CONFIG_PPC44x_SIMPLE) += arches.dtb bamboo.dtb bluestone.dtb 
glacier.dtb
dtb-$(CONFIG_PPC44x_SIMPLE) += eiger.dtb katmai.dtb rainier.dtb redwood.dtb

  yosemite.dtb icon.dtb

Same here, one line is possible.
