This enables LP0 to support suspend / resume on PAZ00.
Ooh. Did you test this out with the AC100 kernel, and have it work? That'd be pretty cool...
diff --git a/board/compal/paz00/Makefile b/board/compal/paz00/Makefile
-COBJS := $(BOARD).o -COBJS += ../../nvidia/common/board.o +COBJS-y := $(BOARD).o +COBJS-y += ../../nvidia/common/board.o +COBJS-$(CONFIG_TEGRA_CLOCK_SCALING) += ../../nvidia/common/emc.o
Hmmm. That's odd. I'd expect that to be part of the core Tegra code, rather than something boards have to pull in manually.
Stephen's right - this is already done in ../cpu/tegra20-common/Makefile when CONFIG_TEGRA_CLOCK_SCALING is defined. So no need to change the PAZ00 Makefile.
diff --git a/include/configs/paz00.h b/include/configs/paz00.h
+/* LP0 suspend / resume */ +#define CONFIG_TEGRA20_LP0
That's been renamed CONFIG_TEGRA_LP0 in u-boot-tegra/next.
As part of the pre-work for Tegra30 changes, I've changed generic Tegra defines, labels, etc. to be more non-specific, unless it does really refer to a Tegra20 feature, file, etc. As Stephen says, see u-boot-tegra/next's top commit.
