| * ppc: minimal Freescale P1010RDB board supportRenaud Barbier2014-07-2810-0/+487
| | | | | | | | | | | | | | | | | | | | | | This is a limited board support for the Freescale P1010RDB. The board boots from NOR and output the prompt to the serial port at 115200 bauds. All 3 Ethernet ports are supported by the gianfar driver. I2C devices are accessible on both bus and the memory is initialised by the 85xx DDR driver.

* | sandbox: allow "make ARCH=sandbox allyesconfig"Holger Schurig2014-07-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Compiling the tree with allyesconfig is helpful because different compilers (gcc, clang) or static checkers (e.g. clang's scan-build) can then process and check more code. 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.

Driver support is limited to: - I2C - Ethernet - Serial - NOR flash - PIXIS FPGA System clock configuration is read from the FPGA but has only been tested using a 133MHz system clock and 100MHz DDR clock. Boot arguments are defined in the environment to boot over NFS with a console configured at 115200 bauds.
