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
