[U-Boot] [PATCH v3 4/7] drivers/i2c/omap24xx_i2c.c: move all local variables to SRAM

2012-01-04 Thread Andreas Müller
At old overo boards TWL4030 RTC irq is connected to gpio112. Unfortunately this pin is also used for revision detection. Therefore we need to send shut-up to TWL4030 to avoid reading wrong revision. In SPL this must be done before SDRAM is set up because the type of SDRAM is revision dependent. By
