2013-04-09ARC: remove #ifdef-ed out include of dead headerPaul Bolle
There's no (Kconfig) macro CONFIG_BLOCK_DEV_RAM. (CONFIG_BLK_DEV_RAM does exist though.) But linux/blk.h got killed in 2005 anyway (in a patch titled "kill blk.h"), so these three lines can be removed. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>

* mem size now runtime configured (prev CONFIG_ARC_PLAT_SDRAM_SIZE) * core cpu clk runtime configured (prev CONFIG_ARC_PLAT_CLK) Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Cc: Arnd Bergmann <arnd@arndb.de> Cc: Grant Likely <grant.likely@secretlab.ca>
2013-02-15ARC: [DeviceTree] Basic supportVineet Gupta
This is minimal infrastructure needed for devicetree work. It uses an a sample "skeleton" devicetree - embedded in kernel image - to print the board, manufacturer by parsing the top-level "compatible" string. As of now we don't need any additional "board" specific "machine_desc".
