Subject: ARM: bcm283x: don't always define CONFIG_BCM2835
X-Git-Tag: v2016.05-rc1~154
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=ed7481c7d18fe2c632b6fbe5646b32cefd2dc791;p=oweals%2Fu-boot.git

ARM: bcm283x: don't always define CONFIG_BCM2835

Currently, CONFIG_BCM2835 is defined for all BCM283x builds and _BCM2836
is defined when building for that SoC. That means there isn't a single
define that means "exactly BCM2835". This will complicate future patches
where BCM2835-vs-anything-else needs to be determined simply.

Modify the code to define one or the other of CONFIG_BCM2835/BCM2836 so
future patches are simpler.
