Subject: 'of_compatible' and 'model' imd records are unusable
Date: Fri, 1 Oct 2021 14:46:19 +0300
Message-ID: <20211001144619.6db15b8269c912722bf0f2d0@gmail.com> (raw)

Hi all!

I have cloned barebox c67ada0024da (v2021.08.0) and found that
'of_compatible' and 'model' imd records are unusable.

E.g.

barebox$ make ARCH=arm CROSS_COMPILE=aarch64-linux-gnu- imx_v8_defconfig
barebox$ make ARCH=arm CROSS_COMPILE=aarch64-linux-gnu-
...
images built:
barebox-nxp-imx8mm-evk.img
barebox-prt-prt8mm.img
barebox-nxp-imx8mp-evk.img
barebox-nxp-imx8mq-evk.img
barebox-zii-imx8mq-dev.img
barebox-phytec-phycore-imx8mq.img

barebox$ ./scripts/bareboximd images/barebox-nxp-imx8mm-evk.img
build: #1 Fri Oct 1 10:16:30 UTC 2021
buildsystem version: 
crc32: 0x00000000
release: 2021.08.0
barebox$ 

There is no 'of_compatible' and 'model' imd records in bareboximd output.

So there is no chance to imd_find_type(..., IMD_TYPE_OF_COMPATIBLE)
(see common/bbu.c) in a barebox image file.

scripts/gen-dtb-s puts IMD_TYPE_OF_COMPATIBLE and IMD_TYPE_MODEL
records into barebox_imd_0 section.

BAREBOX_IMD macro (include/asm-generic/barebox.lds.h)
does not KEEP barebox_imd_0 section":

#define BAREBOX_IMD                             \
        STRUCT_ALIGN();                         \
        KEEP(*(.barebox_imd_start))             \
        KEEP(*(.barebox_imd_1*))                \
        *(.barebox_imd_0*)                      \
        KEEP(*(.barebox_imd_end))

KEEPing barebox_imd_0 leads to several 'of_compatible' and 'model' records
in one barebox image file, e.g.:

barebox$ ./scripts/bareboximd images/barebox-prt-prt8mm.img
