* Kbuild: introduce Makefile in arch/$ARCH/Daniel Schwierzeck2014-12-0815-0/+148
| | | | | | | | | | | | | | | Introduce a Makefile under arch/$ARCH/ and include it in the top Makefile (similar to Linux kernel). This allows further refactoringi like moving architecture-specific code out of global makefiles, deprecating config variables (CPU, CPUDIR, SOC) or deprecating arch/$ARCH/config.mk. In contrary to Linux kernel, U-Boot defines the ARCH variable by Kconfig, thus the arch Makefile can only included conditionally after the top config.mk.

* powerpc: mpc8xx: remove hermes board supportMasahiro Yamada2014-12-083-18/+1
| | | | | | | | | | | | | This board sprinkles #ifdef(CONFIG_HERMES) over various global files such as include/common.h, common/board_r.c, common/cmd_bdinfo.c. Let's zap such an ill-behaved board. It has not been converted to generic board yet and mpc8xx is old enough. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Cc: Wolfgang Denk <wd@denx.de> Acked-by: Wolfgang Denk <wd@denx.de>
* ARM: rpi: rename rpi_b to rpiStephen Warren2014-12-081-3/+3

* ARM: rpi_b: detect board revisionStephen Warren2014-12-081-0/+33
| | | | | | | | | | | | | | | | | | | | | | | | Detect the board revision early during boot, and print the decoded model name. Eventually, this information can be used for tasks such as: - Allowing/preventing USB device mode; some models have a USB device on- board so only host mode makes sense. Others connect the SoC directly to the USB connector, so device-mode might make sense. - The on-board USB hub/Ethernet requires different GPIOs to enable it, although luckily the default appears to be fine so far. - The compute module contains an on-board eMMC device, so we could store the environment there. Other models use an SD card and so don't support saving the environment (unless we store it in a file on the FAT boot partition...) Set $fdtfile based on this information. At present, the mainline Linux kernel doesn't contain a separate DTB for most models, but I hope that will change soon.

It includes <asm/gpio.h> and then <asm/gpio.h> includes <asm/arch/gpio.h>. Consequently, all the SoCs that enable CONFIG_OF_CONTROL must have <asm/arch/gpio.h> even if they do not support GPIO. In the first place, GPIO has nothing to do with OF_CONTROL. It is wrong that lib/fdtdec.c includes GPIO functions; it should be split into two files, FDT-common things and GPIO things. It is, however, a pretty big work to fix that correctly. This is a compromised commit to add a dummy <asm/arch/gpio.h> to support OF_CONTROL for UniPhier platform. This dummy header will be removed after FDT-GPIO stuff is fixed correctly. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Reviewed-by: Simon Glass <sjg@chromium.org>
