9 Most devices use Broadcom standard partitions which allows them to be
10 described with the "brcm,bcm947xx-cfe-partitions". Exceptions are:
11 1) TP-LINK devices which use "os-image" partition with TRX containing
12    kernel only + separated rootfs partition.
13 2) Asus RT-AC87U with custom "asus" partition.
14
15 This commit also removes undocumented and unsupported linux,part-probe
16 binding which got accidentally upstreamed while describing SPI
17 controller.
