[U-Boot] [PATCH v6 0/2] mpc8313: ids8313 board updates

[Heiko Schocher]

- add CONFIG_SYS_GENERIC_BOARD to the ids8313 board,
  therefore fdtdec_get_int() is moved out of lib/fdtdec.c
  as lib/fdtdec.c is only compiled if CONFIG_OF_CONTROL
  is defined, but defining this for the ids8313 board
  leads in conjunction with CONFIG_SYS_GENERIC_BOARD
  in booting error:

No valid FDT found - please append one to U-Boot binary, use u-boot-dtb.bin or define CONFIG_OF_EMBED. For sandbox, use -d <file.dtb>

  So move the common used function fdtdec_get_int()
  out of lib/fdtdec.c into lib/fdtdec_common.c

[U-Boot] [PATCH v6 1/2] lib, fdt: move fdtdec_get_int() out of lib/fdtdec.c

[Heiko Schocher]

move fdtdec_get_int() out of lib/fdtdec.c into lib/fdtdec_common.c
as this function is also used, if CONFIG_OF_CONTROL is not
used. Poped up on the ids8313 board using signed FIT images,
and activating CONFIG_SYS_GENERIC_BOARD. Without this patch
it shows on boot:

No valid FDT found - please append one to U-Boot binary, use u-boot-dtb.bin or define CONFIG_OF_EMBED. For sandbox, use -d <file.dtb>

With this patch, it boots again with CONFIG_SYS_GENERIC_BOARD
enabled.

- changes for v2:
  - remove fdtdec_get_int() in lib/fdtdec.c
  - only one fdtdec_get_int() implementation
     Tested on the ids8313 board (on host and target side)
- changes for v3:
  use fdt_getprop() instead fdt_getprop_w() so we avoid a cast
  as Simon suggested.
- changes for v4:
  none
- changes for v5:
  - keep debug for non host side as Simon Glass suggested.
  - add Acked-by from Simon Glass
- changes for v6
  - rebased against commit d8a97f934c64a7ba6f11da5e4cc7f3be57fcb82d
  - compile fdtdec_common.c only if CONFIG_OF_CONTROL or CONFIG_FIT
    is enabled, to prevent link errors when using old compilers
    on sparc, blackfin and nds32 architectures, as Tom Rini suggested

OK, but why not:
obj-$(CONFIG_FIT) += fdtdec_common.o
obj-$(CONFIG_OF_CONTROL) += fdtdec_common.o

Since we filter out duplicates I would swear.

If so, I change this.
