| * gpio: allocate gpio_desc table dynamicallySascha Hauer2013-03-141-1/+10
| | | | | | | | | | | | | | | | | | Some systems are runnignfrom a very limited SRAM, but have a huge malloc space in SDRAM. The bss normally is in SRAM, so we should avoid having big structures there. The gpio_desc table is 3072 bytes big, so allocate it dynamically instead.
