* | gpio: Drop asm-generic/gpio.hSascha Hauer2015-08-203-3/+2
|/ | | | | | | | | | Since we no longer have custom gpio function prototypes we can drop the prototypes from asm-generic/gpio.h can add them to include/gpio.h instead. While at it add static inline dummy wrappers for !CONFIG_GENERIC_GPIO so that code using gpios can compile without gpio support. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | Above the 0x800 offset the manufacturer provides the board type, a serial number and the MAC as three simple strings. Extract these strings, provide their value as global variables and set the MAC into the ethernet unit.

| * | PPC/PCM030: fix reference clockJuergen Borleis2015-08-032-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to enable and use USB/OHCI on the MPC5200 the USB PLL register must be set. It's not easy to find a correct value for this register, it seems it depends on the used external reference frequency and some other 'magic' things. There are some values out in the wild for the 33,333333 MHz and 33,333000 MHz reference frequency case, but they are not consistent over the boards. The value used here in this change for the USB PLL register is from the first days of support for this platform and works at least on the reference baseboard.

|/ | | | | | | | | | | | | | | | | | Currently Barebox fails to boot a kernel/devicetree pair on PowerPC. With of_find_node_by_path() the framework uses a global variable to find the root node and fails. With of_find_node_by_path_from() and forwarding the 'root' parameter it works again as expected.

|/ | | | | | | | | | | | | | | Currently, MIPS is the only architecture that needs include/generated/asm-offsets.h, but we have got ./Kbuild file now. It is a good reason to move asm-offsets.h rule from arch/mips/Makefile to ./Kbuild and add dummy asm-offsets.c for the other architectures. asm-offsets.h would be useful for all the architectures.

This patch introduces two new configuration symbols that Kconfig files can depend on. That way, code that is only working where a cache or DMA implementation exists can be opted out.
