[PATCH v3 2/2] ARM i.MX53: Make MX53 EVK bootable
yong.shen at freescale.com
yong.shen at freescale.com
Tue Jan 4 01:22:56 EST 2011
From: Yong Shen <yong.shen at linaro.org>
1. Add entries to Kconfig
2. Add machine definition
3. Add Uart platform data, pad setting and base address
4. Adjust GPIO irq number
Signed-off-by: Yong Shen <yong.shen at linaro.org>
