2017-10-04treewide: replace with error() with pr_err()Masahiro Yamada
U-Boot widely uses error() as a bit noisier variant of printf(). This macro causes name conflict with the following line in include/linux/compiler-gcc.h: # define __compiletime_error(message) __attribute__((error(message))) This prevents us from using __compiletime_error(), and makes it difficult to fully sync BUILD_BUG macros with Linux. (Notice Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().) Let's convert error() into now treewide-available pr_err(). Done with the help of Coccinelle, excluing tools/ directory. The semantic patch I used is as follows: // <smpl> @@@@ -error +pr_err (...) // </smpl> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Simon Glass <sjg@chromium.org> [trini: Re-run Coccinelle] Signed-off-by: Tom Rini <trini@konsulko.com>
2016-07-21ARM: tegra: add IVC protocol implementationStephen Warren
IVC (Inter-VM Communication) protocol is a Tegra-specific IPC (Inter Processor Communication) framework. Within the context of U-Boot, it is typically used for communication between the main CPU and various auxiliary processors. In particular, it will be used to communicate with the BPMP (Boot and Power Management Processor) on Tegra186 in order to manipulate clocks and reset signals.
