Subject: kernel: b53: look for NVRAM's "robo_reset" entry on every platform
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=0de2213eeade7173e49cd36ef95ada750a4cc173;p=librecmc%2Flibrecmc.git

kernel: b53: look for NVRAM's "robo_reset" entry on every platform

Since kernel 4.1 bcm47xx_nvram_gpio_pin() is now defined in a global
header and can be safely called even on non-Broadcom platforms.

This change makes b53 look for "robo_reset" on ARCH_BCM_5301X and
slightly simplifies the code.
