From: Masahiro Yamada Date: Thu, 19 Mar 2015 10:42:56 +0000 (+0900) Subject: ARM: bcm283x: merge BCM2835/BCM2836 directories into mach-bcm283x X-Git-Tag: v2015.04-rc5~43 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=ddf6bd4876a1838bdf3202b34f5a36f165c279b1;p=oweals%2Fu-boot.git ARM: bcm283x: merge BCM2835/BCM2836 directories into mach-bcm283x BCM2835 (used on Raspberry Pi) and BCM2836 (used on Raspberry Pi 2) are similar enough. One of the biggest differences is the ARM processor. It is reasonable to collect the source files into a single place, arch/arm/mach-bcm283x/.
